Trang 11There is no population in the world that has a higher
growth of interest in aesthetic surgery than the East Asian
population It is reported that one in five women in the
Republic of Korea have undergone aesthetic facial surgery
This dramatic increase is multifactorial and is in part
driven by local popular culture and media This trend has
been notable over recent years, with the advent of Korean
popular culture and the associated desire to look like the
famed K-pop stars The look is quite characteristic of Korean
aesthetics, with many patients showing their surgeon
photos of the same Asian media personalities This trend
has become so fashionable that it is no longer a stigma to
undergo cosmetic surgery in the Republic of Korea and
China In fact, it might now be considered a status symbol
and reflect upward mobility in the eyes of many This age
of the “selfie” and Facebook has made “looking good” even
more important to this growing population These social
changes have dramatically increased the demand for Asian
cosmetic surgery, stimulating a significant increase in the
number of surgeons performing the surgery
The aesthetics of the Asian face are constantly changing,
and surgical techniques must change to accommodate
such changes Today, there is often the desire for a rounder
forehead, higher nasal dorsum, narrower nasal tip, and a
less round, more angular mandible and chin Many of these
characteristics may indicate a desire for a more “Western”
look However, there are different degrees of change and this
must be recognized by the surgeon Hong Ryul Jin understands
the importance of this variance from patient to patient This
requires the surgeon performing enough surgeries to have
acquired a number of techniques in their armamentarium
In this book, Dr Jin has compiled an outstanding collection
of chapters written by an expert group of surgeons The
book covers the most updated techniques on contouring the
Asian face covering rhinoplasty, Asian eyelid surgery, facial
contouring, and aging-face surgery The book also covers
the rapidly changing field of nonsurgical treatments, such
as botulinum toxin, fillers, and lasers
In the section on rhinoplasty, the authors discuss
the use of implants and autologous materials for Asian
augmentation rhinoplasty The difference in these techniques
is very significant and is reflected in these writings Use of
implants continues to be the most commonly used method
to augment the nose Nuances in the techniques are discussed
in great detail and are covered by several authors Combined
techniques using alloplastic materials for dorsal augmentation
and ear cartilage for the nasal tip have become popular
to avoid some of the potential complications of extending
alloplastic implants into the nasal tip The use of costal cartilage for augmentation is discussed in detail, describing techniques used to stabilize the nasal tip and augment the nasal dorsum Also covered are the nuances of performing dorsal augmentation with costal cartilage and how to minimize the likelihood of warping Popular techniques, such
as diced cartilage for dorsal augmentation and tip grafting, are covered as well
The many techniques available for managing the Asian eyelid are covered, including incisional and nonincisional suture techniques, as well as conventional incisional techniques Precision measurement and marking, anesthetic injections, incision placement, management of the fixation method, postoperative care, and managing complications are all discussed Also covered is the management of the epicanthal fold
In the section on facial contouring, the chapters cover management of the Asian malar region, mandible, perialar augmentation, chin augmentation, masseter muscle contouring, forehead contouring, and complications Also covered are the nuances of facial contouring that provide the surgeon with many options for creating a more aesthetically pleasing Asian face
The section on nonsurgical management covers the use of botulinum toxin for facial muscle contouring, brow contouring, and rhytid management This section also covers fat injections and contouring using autologous fat Laser resurfacing is discussed as well
Dr Jin has been a strong academic figure in Korea for many years and has become well known around the world
He has frequently lectured in the United States and all over Asia He is now considered an international expert
on Asian rhinoplasty and Asian facial cosmetic surgery His international influence is reflected in the diversity
of the authors contributing to his book, and he has done
a masterful job editing this work Readers will find this book comprehensive in its content and detail of surgical descriptions and use of quality operative photography and illustrations This book is an essential reference for the surgeon interested in providing the best outcomes in Asian aesthetic facial surgery

Trang 12Foreword
Hong Ryul Jin has led the way in creating a unique book on
aesthetic facial surgery for the East Asian patient There
are many unique variances with patients from this region
of the world, and they have put together a collection of
chapters that cover all aspects of facial aesthetic surgery
as it pertains to the Asian face The book highlights the
many nuances in facial aesthetic surgery in this group,
and any surgeon who has the occasional Asian patient
will be well served to have this edition in his or her
reference library
A solid portion of this book is dedicated to the
techniques of Asian rhinoplasty It is not limited to strictly
alloplastic dorsal implants, but covers many subtleties that
are often required with Asian patients The third section
is dedicated to the periorbital rejuvenation of the Asian
patient, including ptosis and the double eyelid procedure
There are intricacies to this procedure that distinguish
a good from a great result, and this book captures them well The remaining sections touch on other procedures performed in facial aesthetic surgery, including facial bone contouring, minimally invasive and office based procedures, and hair rejuvenation
Herein is a collection of many authors with vast experience in facial aesthetic surgery in the Asian population It is comprehensive, eloquently written, and will serve as an invaluable resource for years to come Dr Jin is to be congratulated for a terrific book

Trang 13Aesthetic facial plastic surgery has come under the spotlight
in East Asian countries in the past two decades Korea came
under the spotlight in this field recently and intrigued many
from all corners of the world to come, learn, and update
their techniques It is my hope that this knowledge can be
shared far and wide with the English speaking crowd, who
has been finding it difficult to access information that has
been passed on in various Asian languages
The chapters in this book describe most of what you
need to know about aesthetic plastic surgery on the face
The chapters were written by my renowned colleagues in
their respective specialties, detailing special techniques and
potential pitfalls These details do not come from overnight
enlightenment, but rather reflect experience and learning accumulated over decades of surgeries The content in this book is highly scientific and evidence based, which means
it has proven to be safe and efficient This book not only focuses on introducing techniques that are new, but teaches the basic concepts of how-to-do-it in a structured manner
to ensure that readers are able to clearly conceptualize the techniques and theories behind every maneuver
I sincerely hope and expect that this book will guide the new surgeons venturing into aesthetic plastic surgery of the Asian face, as well as provide valuable information to the others

■ Introduction
The recent surge in the number of people seeking aesthetic
facial surgery is a testament to the emphasis placed on one’s
looks as a way to gain considerable leverage in society The
new movement also involves the concept of eternal
youth-fulness; being young is considered attractive, and looking
younger can improve the competitiveness of a worker.1,2
This trend, which started in Western countries around the
end of the twentieth century, is fast becoming worldwide
As of this writing Asia is the most actively growing
economy in the world With more than half of the world’s
population residing on this continent, the impact of any
movement in Asia will be influential.3 With the population
getting more affluent and with the increasing affordability
of a higher standard of living, the past 10 years have seen
many Asians seeking aesthetic procedures to enhance their
facial features or to attenuate the aging process Although
the broad term Asians is generally used to denote people
who originate from Asia, in truth various ethnicities and
races with different facial morphologies reside in Asia
West and South Asia stretches to Turkey and India, where
Caucasoid people (i.e., Turks and Indians) are found In
Pearls
• Asians, particularly those in East Asia, have seen
rapid development in the field of aesthetic facial
plastic surgery, especially in the refinement of
Asian-specific techniques, over the past two decades
• The typical Asian belief in not altering the physical
appearance of one’s face, attributed to respect for
the elderly and one’s ancestors, has evolved with
globalization, resulting in a more neutralized Asian
culture, which is a cross between East and West
More Asians realize that to be at the leading edge of
society, an attractive appearance plays an important
role in determining success There has been a shift
in social acceptance of aesthetic surgery, and we see
more demand for it than ever before
• East Asian features of the face are discussed in detail
in the following chapters, with particular attention
to single-eyelid, small palpebral aperture, flat nasal
bridge and tip, malar prominence, broad mandible,
retruded premaxilla, and many other Asian-specific
aesthetic surgeries
• Common aesthetic surgeries of East Asians also include double-eyelid surgery, epicanthoplasty, rhinoplasty, facial bone contouring surgery, fat injection, and many other techniques discussed in this book
• Newer techniques, including the combination
of nonsurgical techniques in facial rejuvenation such as fillers and botulinum toxin, and laser hair removal and hair transplantation specific to East Asian characteristics, are discussed in detail The pros and cons of nonsurgical techniques such as laser and ultrasound for facial rejuvenation are also thoroughly described to keep readers updated with the latest technologies and the options available to achieve desired outcomes
• Most important, this book not only contains surgical techniques and pearls from surgeons who are experts in their respective fields of aesthetic facial plastic surgery, but also incorporates comments on pitfalls and complications, and how to overcome them, in detail
East Asia, where China, Korea, and Japan are located, ple possess East Asian features Although East Asians are grouped in the Mongoloid strain along with the Southeast Asians (Indonesians, Thai, Polynesians, etc.), the facial fea-tures among the Mongoloids are still quite distinct from each other.3 Fig 1.1 depicts the average of different beauti-
peo-ful Asian faces as described by Rhee.4 Indians, Chinese, and Japanese are all considered Asians; however, their facial features can be quite different
Due to Asia’s long-standing trade routes connecting East and West, modern Asian cities are often comprised
of multiple ethnic groups, reflecting the modern trends of interracial marriages and globalization There is a rapidly transforming effect of globalization on facial features as well, although at this time we still see rather characteristic Oriental features among East Asians
Aesthetic facial surgery in East Asia has expanded and developed at an exponential rate in the past two decades Such rapid progress has enabled us to develop surgical techniques suitable for Asians and to accumulate a con-
siderable amount of experience (Fig 1.2) The new skill
sets and experience have been translated into technical advancement and better surgical outcomes Those experi-ences and advances in aesthetic facial surgery more suited

Trang 23tures, such as double eyelids and tall, well-defined noses Fair skin is seen as the marker of class One ancient saying
in Japanese, Korean, and Chinese societies goes, “A white complexion overrides three appearance flaws,”6 emphasiz-ing the long-standing importance of light-colored skin in multiple countries across Asia This was reinforced during the Western colonization period, when the Europeans were present in Asia and enjoyed high social status In “The His-tory of White People,” Neil Painter even argued that Cau-casians produce “the most beautiful race of men” and that Chinese eyes are an “offence to beauty.”7 The ideal beauty
of Caucasians was once the well-accepted definition of beauty in Asia
Recently, Asian countries have become stronger and more influential economically Scholars have started to debate about “Eurocentric” beauty and the phenomenon
in Asia where it has become the norm to alter one’s facial appearance using plastic surgery to be more Westernized With growing confidence within Asian society, however, Asians have started to embrace their ethnic features The fusion of certain desirable Western features with Asian features is now seen as the ideal form of beauty in Asia The key concept now is to blend attractive features rather than having a certain defined template, a concept that has been heavily criticized and is rapidly falling out of favor The good-looking features are, of course, those that suit a person’s facial structure, personality, and the person as a whole Enhancement rather than alteration of the facial features has become the new trend
Statistics show that up to 58% of women in Korea have plastic surgery by the age of 50.1,8 The percentage is grow-ing in their male counterparts too The desire to obtain aesthetic plastic surgery is often driven by the psychoso-cial aspiration of the patient Rapid development in this field is largely driven by the need to appear more attrac-tive in order to be better accepted in a society that places
a lot of emphasis on beauty and pleasant appearance Looking more beautiful becomes an investment to achieve higher socioeconomic status and to ensure one will find a wealthy romantic partner Thus a new culture or trend has emerged, unstoppable by past cultural beliefs and taboos, and strongly driven by novel concept of beauty, wealth, and
a good life As this concept has grown, the subjects seeking cosmetic enhancement have become younger and younger
As Korean dramas and movies have become more popular throughout Asia, so has the influence of the Korean defini-tion of beauty spread all across Asia This phenomenon of
“Han Ryu” (the Korean trend) was popular among viewers
of all ages With attractive actors and actresses portrayed
as heroes and heroines, many fantasized becoming like one
of them, which could be achieved by altering their looks.This trend became a strong driving force in the devel-opment of aesthetic surgery in Asia, enabling surgeons to grow and achieve a new level of understanding of aesthetic surgeries However, it is up to the conscience of individual practitioners to guard the sanctity of this field, preventing
for Asians are becoming more and more popular, especially
among the more affluent Asians living in the Western
coun-tries Authors of this book believe there is no better time
than now to have our knowledge and experience gathered
and shared to stimulate more development in this field
Many years have passed since the introduction of
specific techniques for Asian aesthetic surgery Much has
evolved over the years, and the current focus seems to be
on refining the techniques to address the stigma faced by
Asian patients Although we still find a handful of patients
coming to the surgeon wanting to look like a particular
pub-lic figure, many are steering away from that trend Patients
these days often request a natural-looking face and wish
to enhance their current appearance while retaining their
facial characteristics, and they especially want to prevent
their plastic surgeries from being noticed by others While
embracing their existing facial characteristics, patients
pre-fer not to look the same as others who desire the ideal
com-position of a beautiful face, albeit all similar looking This
has resulted in surgeons reinventing themselves and
mov-ing into the next level of aesthetic facial surgery, combinmov-ing
less invasive procedures with surgery whenever possible
The art of combining nonsurgical and surgical techniques
to create a beautiful face will no longer be based on a gut
feeling but will be objectively described in this book
■ The Change in Cultural
Beliefs and the Modernization
of Asian Thinking
The Asian desire for a pleasant face is heavily influenced by
facial physiognomy in the past The combinations of
pleas-ant-looking features described in the ancient books were
illustrated with pictures of faces that dictated the future of
a person, down to the position of moles on the face and
body.5 There was a realization of the need for an
aestheti-cally pleasing face, but few other than Shusrata ventured
into the aesthetic surgical field Individuals with
pleasant-looking faces were more likely to be judged to have a good
life and a good job, and those with unpleasant-looking
features were often associated with socially less
respect-able jobs or even criminality The latter types of faces were
deemed inauspicious and still very much influence how
a person is judged in modern society Despite this, there
was little development in this field Few wanted to change
their looks surgically, partly due to the unrefined state of
surgical skills at that time and the strong influence of
Con-fucianism all over Asia, which emphasized the sanctity of
the physical body as a sacred gift from our parents Altering
one’s physical appearance was considered disrespectful to
one’s ancestors.1
As globalization and Westernization exerted more
influence in Asian society via Western media, the
defini-tion of beauty became associated with white Caucasian

5 The narrow and relatively small palpebral aperture results in small eyes This has resulted in many techniques invented and modified over the past decade to increase the palpebral aperture by lateral canthoplasty Proper consideration of the anatomy involved in lateral and medial epicanthoplasty should be given before the surgery is done to prevent later complications such as lower eyelid ectropion
6 A flat nasal bridge and a poorly defined cartilaginous structure of the nose results in poor projection of the nose
7 There is a smaller nasal pyramid with shorter nasal bone length in Asians compared with other ethnicities A study done by Naser and Boroujeni concluded that the nasal bone length studied in the skulls of Koreans was smaller than in American Indians, Anatolians, Iranians, and African Americans.9The soft and small nasal septum encountered sometimes poses difficulty to the surgeon needing
a cartilage graft from the nasal septum Due to this, the use of homologous and autologous rib cartilage grafts has become popular when synthetic implants are not suitable or not preferred by patients Patients should be adequately counseled, as the likelihood of needing a rib graft is higher in Asian patients
8 The nasal skin is thick with abundant sebaceous glands This makes maneuvering the nasal tip substantially more technically demanding
9 Asians possess different skin properties compared with other racial groups Asians are known to have
a thinner stratum corneum, the smallest in terms of pore size and pore numbers, and the highest water and lipid content in the stratum corneum compared with other peoples Their skin is also known
to have the weakest chemical barrier All these characteristics signify that topical drug penetration
is the best in Asian skin and that the formation
of wrinkles is less in Asians Such anatomical differences in the epidermal layer of the Asian skin make management of scars and skin lesions different
in the Asian population
10 Asians have a high malar prominence due to a prominent zygomatic body or arch
11 The broad mandibular angle is associated with masseter hypertrophy
12 Asians’ hair is thick and coarse, is round in shape, and grows faster Asians also have a higher prevalence of curly hair, but thick and straight hair is predominant among East Asians These anatomic differences in Asian hair compared with Caucasian hair require hair transplant equipment and procedures that are different from those that are conventionally used
To successfully address the above issues, one should understand the unique anatomic presentation of the Asian face to properly modify and make refined adjustments to the generic techniques presented in earlier textbooks
the double-edged sword of harm to our patients and to the
practice of aesthetic surgery, by prescribing only
appro-priate and scientifically sound procedures to patients and
providing the best surgical practices tested by time and
experience
■ Anatomic Differences and
Their Implications
Most East Asians share the phenotypic features represented
by the Mongoloid profile It is currently the most widely
dis-tributed physical type, constituting over a third of the human
species Therefore, it is not surprising to find that many living
throughout Asia share the same facial features Mongoloid
features are typically represented by epicanthal folds and
neoteny While some of the features, such as the single eyelid
and maxillary retrusion, are not common among
Western-ers, they are widely encountered in Asians, with
double-eyelid surgery being the most popular plastic surgery sought
(Fig 1.3) High cheekbones, a broad mandibular angle, and
a low nasal profile are features in Asians that are not highly
favored, and are often associated with aggression or
manli-ness Generally, a well-projected nose is preferred
A low nasal bridge is not limited to Mongoloids The
Malay people found in most of Southeast Asia across
the Philippines, Malaysia, Thailand, and Indonesia often
request changes to address a low nasal bridge and wide
flaring ala (Fig 1.4).
Because the anatomy of the eyelids, nose, and facial
bones in Asians differs significantly from that of Caucasians,
a unique management strategy is required to successfully
improve the aesthetic outcome The management strategy
should be aimed at handling anatomic issues specific to the
Asian face such as the following:
1 The pretarsal skin of the upper eyelid is not attached
to the levator palpebrae muscle, leading to a poorly
defined superior palpebral fold The construction of a
double eyelid that suits the morphology of an Asian
face is different from practice involving Caucasians
2 Excessive fat is distributed between the orbicularis
oculi muscle and the levator muscle with relatively
thick palpebral skin and orbicularis oculi muscles
3 Orbits are smaller with a more protruding orbital
margin compared with Westerners Therefore,
recreating the features of Caucasian eyelids has
proven unsuitable Aesthetic eye surgery should be
refined and subtle rather than dramatic, or it can
give rise to a thick, deep upper eyelid, which is not
suitable for smaller orbits

prominent medial epicanthal fold A variety of
techniques (and their pros and cons) to eliminate
the obtunded angle will be described in detail in the
chapter on epicanthoplasty

Such refinement in surgical techniques is also seen in rhinoplasty surgeries, with more versatile use of alloplas-tic materials such as Gore-Tex (W.L Gore & Associates Inc., Flagstaff, Arizona) and homologous cartilage in reconstruc-tion of the nose Nasal augmentation is rarely a need for the Western patient In contrast, almost every East Asian patient requests nasal dorsal augmentation In the past two decades, we have seen the popularity of silicone implants fall and the subsequent increased acceptance of Gore-Tex
as a more versatile implant material Although the use of silicone implants is declining due to the higher complica-tion rate and rigid appearance of the nasal dorsum, we see a current trend of surgeons carving silicone implants more judiciously, getting rid of the L-strut and combining use of the implant with other soft tissue to produce a softer and natural look and reducing the rate of implant extru-sion This allows the surgeon to continue using the silicone implant, which does have some advantages compared with other choices of implants On the other hand, continuous trials using autologous costal cartilage for dorsal augmen-tation have shown much improvement over the years with improved reliability and consistency We have seen a shift recently toward the increased popularity of autologous grafts compared with synthetic grafts due to the superior-ity of the autologous graft in resisting infection and pre-venting long-term complications.10,11
Recently, tip surgery in addition to dorsal tion has become a standard procedure undertaken dur-ing rhinoplasty The tip has to be properly supported and rotated after dorsal augmentation to produce a natural, pleasant-looking nose This is largely achieved by using
augmenta-■ Modification and Refinement
of Surgical Techniques
To enhance existing Asian facial characteristics, refinement of
the techniques is often required Such refinement is well
illus-trated by the various techniques of epicanthoplasty to address
a slightly different curve of the medial epicanthus, suturing
techniques to make eyes with ptotic or puffy upper eyelids
appear larger and more relaxed, and lateral canthopexy to
achieve a more attractive and lively appearance of the eyes
The conventional methods of epicanthoplasty, such as
Y-V, V-W, and W plasty, were noted to give rise to unsightly
scars As surgeons in Asia accumulated more experience,
many new techniques were developed, such as the
pal-pebral margin incision method (Chen, medial
epicantho-plasty), with others commonly combining blepharoplasty
with medial epicanthoplasty by extending the incision,
resulting in an obscured scar With the increasing number
of lateral canthoplasties done to widen the palpebral
aper-ture of the Asian eye, complications such as hypertrophic
scars and scar contracture causing the palpebral fissure to
become narrow again are possible The procedure may also
result in asymmetrical results due to unpredictable scar
formation In cases where the lateral canthal ligament is
cut to achieve maximal opening of the palpebral aperture,
lower eyelid ectropion and sagging may occur in the future
as the soft tissue and muscular support is weakened
There-fore, such surgeries are never to be taken lightly and should
be done only after sufficient risk and benefit assessment

Trang 27would prove too drastic and destructive It also plays an important role as an adjunct to many cosmetic procedures Fat grafting techniques have progressed from the use of crude fat lobules to microfat grafts, giving rise to improved longevity in the recipient site The use of fat grafts is also very popular to improve the contour of facial topography, proving to be very versatile in creating whatever topogra-phy is desired With their expertise in this field, the authors
of this book are able to share many of their valuable ences in refining and perfecting the use of this technique to improve surgical outcomes
experi-Hair restoration has also become a popular procedure done for aesthetic purposes in Asia in recent years It is not only popular for males experiencing androgenic hair loss but also for females who wish to reshape the face and to soften the outline of the face by altering the hair-line More females are seeking hair transplant procedures
to extend the hairline at the temporal region, thus ing the muscularity of the face, or to change the face to a more favorable “oval” shape Hair transplantation is quite different in Asians This is due to their thicker and coarser hair structure, a broader base for the follicles, and a higher incidence of keloid-forming scars compared with Cau-casians Therefore, follicular unit extraction and use of a micropunch designed to minimize scarring and maximize hair follicle extraction have become more popular than the conventional single-strip harvesting technique Due to the thicker and coarser hair found in Asians, during follicular unit extraction the direction and depth of the scorings must be precise and the base has to be broad enough so that the germinal unit of the hair will not be damaged As curly hair is more common in Asians than in Caucasians, the direction of the implantation has to be considered so as not to have unnatural hair growing in different directions These and many other pearls related to hair restoration in the Asian population will be presented in the correspond-ing chapters
reduc-We will also deal with facial hair removal using laser for aesthetic purposes The width of the forehead forms the shape of the face in the superior third The forehead
is also the location of the “chakra” where the third eye
or sixth sense resides as per Sanskrit scriptures A row forehead puts too much emphasis on the middle and lower parts of the face and is often associated with lack
nar-of radiance A balanced forehead can be created with manent removal of the appropriate amount of hair with least problem of dyspigmentation in Asians, who gener-ally have darker skin tone Nd:YAG laser has proven to be
per-a good choice for hper-air reduction in Asiper-ans, compper-ared with conventional diode laser, and was found to be superior in hair reduction.12 Many studies are still being conducted
on laser hair removal regarding the paradoxical effect of fine hair growth postremoval An exciting journey lies ahead, with more details revealed in the chapter on laser hair removal
the open approach Tip rotation achieved with a septal
extension graft and the use of multiple layers of
autolo-gous material such as muscle fascia and cartilage
cou-pled with some suture techniques are the most popular
options employed now Both patients and surgeons have
shied away from synthetic material for tip work due to
the high extrusion rate and the subsequent disastrous
sequelae of an infection Autologous material is time
tested and shown to have the least complications and
best results so far The overaggressive tip work associated
with overambitious maneuvers is highly advised against,
as too much of a good thing in any circumstances will only
result in the opposite of the desired effect
Overprojec-tion and rotaOverprojec-tion of the tip is associated with a deformed
tip in the long run as a certain degree of resorption of
the cartilage graft used and scarring of soft tissue will
cause instability of the tip constructed Therefore, from
our experience, judicious adjustment of the dorsum with
a matching tip should be the limit to such augmentation
procedures, although it may be very inviting
intraopera-tively to achieve a maximum effect
Understanding the specific anatomic differences
in Asians has enabled us to combine the use of various
adjunctive surgeries and procedures with rhinoplasty to
produce a more favorable outcome than is possible with
just rhinoplasty alone Some of these procedures include
paranasal implant, chin implant, nasal alar resection, and
columella-lengthening flaps to address issues like
maxil-lary retrusion, retrognathia, wide nasal ala, and short
col-umella, respectively, which are common problems found
in Asians Asian surgeons have also perfected their skills
in malar reduction, which is a more common procedure
in the East compared with the West Previous experience
has resulted in some cases of facial sagging, facial
asym-metry, and downward movement of the malar point The
reduction of the angle of the mandible is also a common
aesthetic surgery in Asia as opposed to the West, as a
softer look and a “V-shaped” face are strongly favored
in Asia Asian surgeons have substantially more
expe-rience when it comes to this kind of skeletal reduction
work Other skeletal alteration surgeries that are
popu-lar in Asia include orthognathic surgery such as
bimax-illary advancement/reduction or mandibular reduction/
advancement, which can be solely for cosmetic purposes
These surgeries were originally intended to correct
con-genital deformities related to functional problems such
as malocclusion As the appearance of a protruding
man-dible or retruding maxilla is unattractive, patients these
days are willing to undergo surgeries even without
func-tional problems, and even when the risk of associated
complications outweighs the benefit
The growing popularity of fat grafting has improved
patient satisfaction tremendously Fat grafting produces a
long-lasting effect in facial rejuvenation This is especially
true in the younger patients in whom a surgical face lift

■ Conclusion
New trends, concepts, and techniques are rapidly appearing
in Asia for aesthetic facial plastic surgery This trend not be ignored and will become our strength as experience grows Many of the new techniques should be reviewed judiciously and meticulously and used carefully Therefore, this new book is opening up a whole new chapter in aes-thetic facial surgery for East Asians

■ Procedural Techniques
Facial cosmetic procedures can no longer rely on surgery
alone Many practitioners can no longer afford to shun the
use of laser, intense pulsed light (IPL), and many other
non-surgical techniques to achieve better outcomes Although
many of these techniques do not provide long-term effects
as good as surgical intervention, they often complement
the surgical outcome or delay surgical intervention
appro-priately Examples are the use of thread lifting for younger
patients where a surgical face lift is too drastic and
unnatu-ral, laser or high-frequency focused ultrasound (HIFU) in
face lifting for mild soft tissue sagging, laser and/or IPL in
resurfacing various types of scars and reconstructed flaps,
and filler injection for specific facial contour
augmenta-tion in limited areas Various types of filler injecaugmenta-tion,
rang-ing from collagen, hyaluronic acid, and calcium hydroxyl
apatite to poly-L-lactic acid and platelet-rich plasma, are
becoming more and more accessible to patients as they are
noninvasive, are technically easier to apply, and provide
a reasonable outcome for a nonsurgical procedure At the
time this book is being prepared, hyaluronic acid remains
the most widely used filler due to its longevity and its safety
profile compared with the other types of fillers It is
impor-tant, however, that the reader be able to discern the
ben-efit of the filler injection and verify that it outweighs the
risks of its usage, which include, in the worst-case scenario,
blindness due to embolism of the retinal vessels.13 Although
not as severe as blindness, other complications, such as skin
necrosis of the injected area, should not be overlooked as
reconstruction of the affected area can be very troublesome
if it involves a large area requiring complex reconstructive
techniques The first sign of the grievous complications just
mentioned (pain in the patient postinjection) should not
be simply disregarded, and prompt usage of hyaluronidase
with or without hyperbaric oxygen is called for
Nonsurgical facial rejuvenation is often overlooked by
many surgeons due to its relatively brief history However,
with the growing number of clients preferring nonsurgical
intervention to surgical intervention and its definite role in
complementing surgical outcomes, nonsurgical
interven-tion has survived and is rapidly being reinvented and
diver-sified in providing solutions to facial rejuvenation Although
these techniques need to be further proven with more
stud-ies and research, surgeons should be aware of the
nonsur-gical techniques available in the market because ultimately
patients who need surgery may be those who have
expe-rienced complications from these nonsurgical techniques
In certain circumstances, these nonsurgical techniques can
also be effectively combined with the use of surgical
tech-niques to achieve better results

■ Introduction
The noses of East Asian people are different in many
aspects from Caucasian noses Augmentation rhinoplasty
is one of the most common aesthetic procedures in Asian
countries because of the relatively flat and wide Asian nose
However, augmentation rhinoplasty should be
conserva-tive, preserving the ethnicity to make the nose appear very
natural and harmonious with other facial units In Asian
countries, augmentation rhinoplasty is not a major
recon-structive operation It is regarded as one of the
uncompli-cated common cosmetic procedures It is often regarded as
a trendy operation, and the aesthetic standard of patients
is generally high People want short recovery times and a
quick return to the job, although major augmentation is
frequently required
In this situation, a practical and cost-effective option
for a surgeon is rhinoplasty using an alloplastic implant
Pearls
• For East Asian noses, major augmentation is
frequently required for the nasal dorsum and the tip
• The silicone implant is widely used in Asian
countries because it is easy to use, limitless in
volume, cost-effective, and superior to the auto- or
homograft from the aesthetic viewpoint
• There are two sources of problems related to the
alloplastic implant One is the problems inherent
in the material itself, which can be minimized The
other is problems from technical or judgmental
errors, which are more common and must be
avoided
• Infection is a serious problem though uncommon
Thorough sanitization of the operation field,
including the nasal vestibule and anterior nasal
cavity, is important Care should be taken not to tear
the mucosal barrier using atraumatic techniques
Operation time should be reduced to decrease
the chance of infection The implant must be
immersed in antiseptic solution before and after any
manipulation
• Designing an implant must be individualized The
surgeon should have in mind the desired shape of
the nose Individual anatomic characteristics must
be considered such as the nasofrontal angle, dorsal
contour, and tip projection
• Proper selection of a tip technique is important
According to the tip technique, the design of an implant varies The implant should be connected to the augmented tip smoothly and seamlessly
• Do not try to augment the tip with the implant
Unlike the relatively immobile dorsum, the tip
is highly mobile Therefore, only autologous cartilage must be used for the tip, with appropriate techniques to prevent extrusion and skin problems
An implant placed on the tip is aesthetically unpleasing because it always leads to a rotated tip with an unnaturally thick infratip lobule
• With the use of only autologous cartilage for the tip, skin problems are prevented and more natural outcomes are ensured
• Stacking of multiple layers of onlay grafts is commonly required for sufficient tip projection
in Asians The wing graft should be used in combination with the stacked onlay graft to prevent noticeability of the onlay graft and pinching deformity
• Complication rates of alloplastic implants are medically acceptable Complications are more frequently the result of the surgeon’s technical and judgmental errors, rather than the fault of inherent characteristics of the material itself
Amounts of autologous materials except for costal cartilage are limited for the usual large-volume augmentation How-ever, with the use of costal cartilage, economic and psycho-logical burdens are heavy for patients Other disadvantages include postoperative scarring on the chest, rigidity of the tip, prolonged operation time, and a long recovery period
In addition, the use of costal cartilage is not free of plications Problems of warping and resorption are well known Infection is rare but is possible Therefore, costal cartilage is reserved as a last resort by many surgeons
com-On the other hand, alloplastic implants are ready to use, easy to carve, varied in size, and superior to autolo-gous materials from an aesthetic viewpoint Also, they are not subject to resorption or warping Among the most com-monly used alloplastic materials are silicone, expanded polytetrafluoroethylene (Gore-Tex), and porous high-den-sity polyethylene (Medpor, Stryker, Kalamazoo, Michigan)
Silicone is the most frequently used material in Asian countries It is nonporous, in contrast to the other two

Professional recommendations should be given to the patient after a thorough analysis of the face The relation-ship of the nasal dorsum, tip, philtrum, lips, and mentum with the vertical facial axis should be investigated In ana-lyzing the face, any facial asymmetry must be noted and revealed to the patient before the surgery, because the augmentation rhinoplasty may worsen or accentuate a pre-existing facial asymmetry When the vertical facial axis is skewed or deflected, the augmented nose cannot
be absolutely vertical and straight In patients with cant facial asymmetry, it is better to augment the nose in a different vertical axis from the anatomic dorsum In these patients, nasal bones on the two sides are frequently asym-metric in terms of the width and the slope When the bony asymmetry is significant, the bottom of the implant is bet-ter carved asymmetrically accordingly
signifi-Facial asymmetry commonly accompanies ric nasal alae Pre-existing alar asymmetry makes the nose look deviated even after augmentation to the correct axis Asymmetric alar resection in these patients may not cor-rect the problem satisfactorily Alar asymmetry relating to facial asymmetry is difficult to correct because of its multi-dimensional nature
asymmet-A systemic examination of the nose is performed from
top to bottom (Fig 2.1) The relationship of the forehead
with the nasal root is important for a successful dorsal mentation The Asian forehead is relatively flat and less pro-truding Generally, Caucasians are more dolichocephalic
aug-materials, with no tissue ingrowth or vascularization
seen after implantation Because of its nonporous nature,
it is nonadhesive to surrounding tissue and enclosed in a
fibrous capsule Also, it is free from deformation, easy to
sterilize, and easy to remove when necessary It is relatively
cheap and available in a range of softness values
Expanded polytetrafluoroethylene (ePTFE) is
com-posed of nodules of Teflon interconnected by fibrils of
polytetrafluoroethylene and has a microporous
architec-ture, with pore sizes ranging from 10 to 30 mm Its
poros-ity makes it easily malleable and susceptible to long-term
compression, resulting in volume decrease or deformation
of the implant Its hydrophobic and porous nature makes
the sterilization process using an antiseptic or antibiotic
solution difficult Relatively high cost is another
disadvan-tage For the revision cases, sometimes it is very difficult
to remove the previous ePTFE implant, especially when the
implant is thin, and the duration of implantation is long
When the surrounding soft tissue is removed together
with the implant, the resulting soft tissue irregularity is
extremely difficult to repair
Porous polyethylene (Medpor) consists of a continuous
system of interconnecting pores of size 125 to 250 mm The
vascular and fibrous ingrowth leads to integration and
sta-bilization of the implant The tensile strength of the
mate-rial is very high, contrary to the case for ePTFE Because of
its stiff nature, it should be used with utmost caution in
mobile areas such as the membranous septum or tip
Synthetic implants in rhinoplasty have been a topic of
great controversy In particular, silicone, which is the single
most commonly used implant material in Asian countries,
is a point of worldwide contention.1 Asian noses are
consid-ered more receptive to alloplastic implants because of their
thick skin.2 This is true to some extent, but even thicker
skin cannot resist long-term thinning, extrusion,
inflam-mation, and infection Therefore, proper techniques using
an adequately designed implant must be executed
When an experienced surgeon uses proper techniques,
the complication rate for alloplastic implants is
surpris-ingly low and in a medically acceptable range Recent
stud-ies about the complication rates of alloplastic implants for
augmentation rhinoplasty show that they are much lower
than those in studies from the 1960s and 1970s.3 These
changes are due to improvements in implant design,
con-servative surgical techniques, surgeons having more
expe-rience, and the use of softer silicone
■ Patient Evaluation
The shape and profile of the nose requested by the patient,
and their feasibility or desirability are discussed in this
section Advantages and disadvantages of using alloplastic
implants and possible alternatives to alloplastic materials
are also discussed

aug-mentation rhinoplasty: forehead slope, nasofrontal transition, jections of the nasal tip, premaxilla, and chin
Trang 33pro-with the patient, because it is unrealistic to try to make the sides of the alae completely symmetric In patients with underdevelopment of the maxilla or premaxilla, paranasal
or premaxillary augmentation may be considered as lary procedures of the augmentation rhinoplasty
ancil-However, it should be taken into consideration that acute nasolabial angle is not uncommon in Asians Some Asian noses are beautiful enough even with the acute naso-labial angle, and in some patients acute nasolabial angle is not a concern at all
Patients with protruding lips can benefit from the bination of rhinoplasty, maxillary augmentation, and chin augmentation This combination of surgeries will dramati-cally enhance the facial profile in selected patients
com-■ Surgical Techniques Skin Marking
Skin marking for the augmentation must be done in the sitting position Marking a vertical line for the dorsal aug-mentation is important, because frequently the glabella, nasal dorsum, and nasal tip are off the same vertical axis,
and Asians are more brachiocephalic Brow ridges in Asians
are also not as prominent as in Caucasians As a result,
the nasofrontal angle in Asians is like a gentle and
grace-ful curve rather than an angle Augmentation rhinoplasty
in Asians must preserve this gentle curvaceous transition
from the forehead to the nasal dorsum And the augmented
nose must harmonize with the relatively flat forehead
Therefore, excessive augmentation of the radix area should
be avoided in patients with a flat forehead The proximal
end of the implant should be carefully tapered to
accom-modate to this area and not be visible or palpable Despite
the retruded forehead, if the patient wants a substantial
amount of dorsal augmentation, combined forehead
aug-mentation should be considered Forehead
augmenta-tion surgery is rarely performed in the West; however, it
is a common surgery in Asian countries, using alloplastic
implants or microfat injection
In patients with excessive skin and soft tissue crowding
in the glabellar and nasal root area, the brow lift should be
considered That is because augmentation rhinoplasty may
make this area look heavier and thicker and may worsen
the masculine look in these patients, leading to
unsatisfac-tory outcomes Aged patients tend to have brow ptosis and
a thick soft tissue load in the glabellar area Therefore, a
combined brow lift surgery should be considered in aged
patients and augmentation of the radix area should be
minimized, focusing more on tip augmentation However,
even in young patients having a short distance from
gla-bellar area to nasion, dorsal augmentation may further
shorten the distance, making the nasal root area unnatural
and flattened Therefore, a combined brow lift surgery may
be considered in these young patients also The endoscopic
brow lift is the best option for young patients considering
the effect on the medial brow and minimizing
postopera-tive scarring
The glabellar and nasal root region shows a wide range
of variation even in Asians Therefore, the proximal implant
should be carved carefully according to individual anatomy
to fit in this area Preoperative X-ray may be helpful for
visualization of the bone and soft tissue anatomy of this
area (Fig 2.2) Examination by manual palpation of this
area before or during the operation is also very important
Careful dorsal examination precedes the design of an
implant The nasal bone is examined for its length, width,
and asymmetry Manual palpation along the dorsum is
helpful in revealing soft tissue thickness, presence of hump,
or dorsal irregularity
Skin thickness of nasal tips is quite variable in Asians
For the thin-skinned patients, visibility of grafts or the
implant might be problematic On the other hand, for the
thick-skinned patients with bulbous tips, it is very difficult
to obtain a fine definition of the tip
Wide alae are common in Asians For the enhanced
outcome of dorsal augmentation, alar resection may be
required in some patients If alar asymmetry and
asymmet-ric maxillary development are present, they are discussed
Fig 2.2 A preoperative X-ray helps in planning by visualizing the
bone and soft tissue anatomy of the nose

is required Any blood or secretion in the oral and geal cavity is sucked out repeatedly using a suction catheter through the oral airway during the operation To reduce the secretion, intravenous injection of glycopyrrolate before the surgery is recommended Oxygen supplementation through the oral airway also can be helpful
pharyn-Preparation of the Implant
Before local anesthetic injection, an implant is prepared
and tried on the dorsum (Fig 2.4) The surgeon must check
whether it is suitable for the desired height and desired nasal profile, whether it is well fitted for the nasofrontal angle, and the dorsal configuration Then initial carving is performed using a no 15 surgical blade before the surgery
A correctly designed implant is crucial for a successful outcome Any single implant must be customized accord-ing to individual anatomy The thickness of the implant is decided first Implants with 4 to 5 mm of thickness are most frequently chosen among the 2 to 10 mm thickness range However the thickness is not uniform and varies along the dorsum after carving according to the individual’s ana-tomic characteristics In general, when the nose is low in radix and the tip is well projected, the implant is carved proximally thick and distally thin On the contrary, when the nose is adequately high in radix and the tip is low, the implant is carved proximally thin and distally thick When
a hump is present, the implant is often carved thinner in
the rhinion area (Fig 2.5)
The implant’s shape, especially the distal portion, is also variable according to the preferred tip augmentation technique
The initially carved implant is immersed in antiseptic solution such as hypochlorous acid until its later use The
and augmentation rhinoplasty may accentuate the
devi-ated look of the nose
Therefore, the surgeon must set a vertical line for the
augmentation The line that looks the straightest is
care-fully chosen for the line of augmentation (Fig 2.3) When
the dorsum and tip are vertically misaligned, usually a
ver-tical line extended upward from the tip is more appropriate
for the line of augmentation, rather than the line along the
dorsum, although this is not always the case
The nasal starting point is set and a horizontal line is
marked, usually at the height of the ciliary margins In
gen-eral, when the patient wants a higher dorsum, the line may
be drawn at the height of the supratarsal crease When the
patient wants a more natural look, then the line is drawn
between the ciliary margin and the pupil However, it is
individualized according to the patient’s facial
character-istics This horizontal line also provides a landmark for the
cephalic extent of the subperiosteal dissection
Anesthesia and Positioning
The patient is put under anesthesia in a supine position
and draping is done Augmentation rhinoplasty using
allo-plastic implants is done under general anesthesia or
intra-venous anesthesia with sedation When it is done under
intravenous anesthesia, close monitoring of the respiration
is crucial Maintaining the oral airway during the surgery
Fig 2.3 Skin marking is done in a sitting position using a straight
wooden stick A vertical line is drawn The nasal starting point,
rhinion, and nasal tip are marked
Fig 2.4 The implant is tried on the dorsum for the initial carving.
Trang 35for later closure and there is no risk of notching deformity The columellar flap is elevated in the conventional man-ner Elevation of the skin flap from the tip is on the supra-perichondrial plane for the thin-skinned patients as usual However, for the thick-skinned Asian patient, the defatting procedure is frequently required for debulking the thick soft tissue and for better definition of the tip For the defat-ting procedure, a layer of soft tissue is deliberately left on the cartilage surfaces elevating the skin flap (Fig 2.6).
Because the tip soft tissue is arranged in a layered fashion, it is not quite as difficult to raise the flap with an even thickness This technique is better for smooth and even removal of the soft tissue along the cartilage surfaces than defatting from the undersurface of the skin flap after supraperichondrial elevation There is thick soft tissue on the supratip area also, and it can be removed or preserved depending on the situation On the cartilaginous dorsum, the plane is changed to the supraperichondrial plane
Creation of the Periosteal Pocket
As dissection proceeds on the nasal bone, the plane is
changed again to the subperiosteal plane (Fig 2.7) It is
very important to accurately raise the periosteal flap from the nasal bone When the implant is not correctly placed in the subperiosteal space, the implant tends to be more mov-able and more visible To elevate the periosteum precisely,
it is better to use a sharp and narrow tip elevator, such as the Joseph elevator, at first When the subperiosteal space is correctly raised partially, then a wider elevator is inserted and the space is widened If a wide and blunt instrument is used from the start, the periosteum is easily torn
Close to the nasofrontal suture line, bleeding is likely
to ensue because of proximity of vessels to the suture line
hypochlorous acid is suitable for this purpose because it is
clear in nature and relatively less toxic, nonirritating, and
potent
Harvest of Ear Cartilage
After local anesthetic injections at the nose and the ear,
conchal cartilage is harvested first when it is expected to
be necessary Conchal cartilage is harvested commonly
through a postauricular incision And it is harvested from
the cavum concha and cymba concha separately, leaving
the crus of helix as a bridge This valuable anatomic
land-mark of the auricle is best preserved for aesthetic purposes
and structural support, and to maintain the abundant
neu-rovascular supply of this area The harvested conchal
carti-lages are preserved in the antibiotic solution
Incision and Elevation of the Skin Flap
For an open rhinoplasty, transcolumellar and marginal
incisions are marked first In Asian patients, occasionally
the caudal margins of the alar cartilages are not prominent
through the vestibular skin Therefore, marking for
mar-ginal incision is helpful for a precise and symmetric
inci-sion The marginal incision is placed 1 mm anterior to the
caudal margin of the alar cartilages, because this is better
Fig 2.5 The initial carving is done using a no 15 surgical blade
The three most common shapes of implants are shown (top,
proxi-mally thin and distally thick; middle, proxiproxi-mally thick and distally
thin; bottom, anatomically carved) Implants are further
custom-ized during the surgery

in the supratip area that was left deliberately during flap elevation for the defatting procedure is now removed Clear identification and delineation of the cartilage margins are
important at this stage for later procedures (Fig 2.8)
Mar-ginal incisions are extended laterally as needed, especially when the tension on the augmented tip is expected to be high The piriform ligaments may also be further released as necessary For more release of tension, the scroll area may
be dissected However, the dissection should be as vative as possible, because more dissection will cause more distortion, scar formation, and unpredictability
conser-Harvest of Septal Cartilage
Next the membranous septum is dissected and the caudal margin of the septum is identified The septal cartilage is harvested, leaving the L-strut In Asians, the septal cartilage
is frequently weak and small In those patients with a weak septum, more of the septal cartilage should be preserved than the conventional 1 cm width for the dorsal and cau-dal strut to maintain the structural stability Therefore, the amount of harvested septum is frequently very small Even when the harvested amount of septal cartilage is enough, the caudal septum is too weak and frail to provide long-term stable support for the septal extension graft In this regard, tip surgery using septal cartilage only has clear limitations in many Asian patients However, despite these drawbacks, the septal extension graft is still one of the most reliable tip techniques for Asians It provides tip projection and rotation/derotation itself, as well as providing strong
medial support for combined onlay grafts (Fig 2.9)
How-If this bleeding is not controlled correctly, hematoma can
arise postoperatively on the nasal root Hematoma is a
seri-ous complication, because if not adequately treated, it will
be accompanied by bacterial infection The position of the
implant may also be changed by a hematoma
Therefore, it is better not to dissect overly extensively
in the cephalic direction if it is not necessary Excessive
cephalic dissection may also lead to cephalic migration of
the implant
The subperiosteal pocket is widened laterally as needed
The space should be close to symmetric and adequately
wide for the implant to be snugly placed inside When the
subperiosteal pocket is too small, the implant may not be
placed properly and may later be displaced or deviated On
the other hand, an overly wide pocket is also a common
cause of early postoperative displacement of the implant
Defatting and Release of
Ligamentous Attachments
After the dissection along the dorsum is finished, the tip
surgery is initiated A successful dorsal augmentation
can-not be accomplished without a successful tip augmentation
Fig 2.7 The dissection plane is supraperichondrial on the
carti-laginous dorsum and subperiosteal on the nasal bone
Fig 2.8 Cartilage margins are clearly delineated after the
defat-ting procedure
Trang 37Preparation of the Stacked Onlay Graft
According to the estimated amount of tip projection, onlay grafts using septal or auricular cartilage are pre-pared Because the amount of septal cartilage is limited in Asians usually, auricular cartilage is generally used for this purpose
Stacking of multiple onlay grafts is frequently sary because the required amount of tip augmentation is commonly substantial in Asians.4 Stacking of two or three layers of auricular cartilage is usually required, although the number is variable The layered cartilages may be sutured together Three layers of auricular cartilage will be around 5 mm in thickness
neces-The graft should be cephalo-caudally long enough to be placed over the domes of the alar cartilages The margins
of the graft are meticulously trimmed to be devoid of any sharp edges
When the stacked onlay grafts are prepared, the same cephalo-caudal length as used for the graft is resected
from the distal implant (Fig 2.11) The removed part of
the implant is replaced by the onlay graft, which is sutured
to the cut end of the implant By suturing the graft to the implant, an unbroken, seamless transition from the dorsum
to the tip is ensured Tip mobility is mildly decreased but not restricted by suturing the graft to the implant How-ever, when the septal extension graft is used, decreased tip mobility is an inevitable trade-off The thickness of the distal end of the implant is adjusted to match the thickness
of the onlay graft The distal part of the implant may be beveled according to the inclination of the lateral crura of the alar cartilages
The stacked onlay graft is supported medially by the septal extension graft Without strong medial support, the
ever, excessive tension from overzealous tip augmentation
relying only on the septal extension graft will be a cause of
septal buckling, long-term resorption or weakening of the
caudal septum, and tip drooping Therefore, a minimal to
moderate amount of tension should be applied,
consider-ing the strength of the individual septal cartilage
After harvesting the septal cartilage, osteotomies are
performed if required Although the osteotomy is not a
contraindication for alloplastic dorsal augmentation, the
osteotomy should be as atraumatic as possible and
muco-sal tearing should be minimized to exclude the chance of
ascending bacterial infection
Insertion of the Implant
The prefabricated implant is now inserted in the dorsal
pocket (Fig 2.10) The excessive length outside the pocket
is trimmed The profile of the nose is closely examined and
compared with the planned shape The conformity of the
implant on the nasal dorsum is closely checked The
proxi-mal end should not be visible, readily palpable, or
mov-able The dorsum should be smooth and straight, or mildly
concave in women To obtain the desired shape and dorsal
smoothness, repeated carving and trials of the implant may
be necessary
The projection and rotation of the tip, which is
tem-porarily formed by the distal tip of the implant, is
care-fully examined The implant may be used as a dummy for
the tip surgery The surgeon can estimate the required
amount of projection by the thickness of the implant tip
And also the surgeon can estimate the desired amount of
rotation/derotation by moving the tip of the implant back

cases of alar rim retraction, because it is securely fixed to the onlay graft to provide strong support against retraction, compared with the alar rim graft
In a widely used technique for alloplastic augmentation
in Asia, the tip of the implant (straight or L-shaped) is placed
on top of the alar cartilages, and then a piece of autologous cartilage is laid on top of (onlay-like) or in front of (shield-like) the distal implant in an attempt to decrease the risk of skin problems such as extrusion These techniques provide tip projection and rotation with relative ease, and produce fair outcomes in selected cases, especially in those with under-projected and under-rotated nasal tips However, these techniques have apparent disadvantages The resul-tant tip tends to be over-rotated and unnatural, because the projection and rotation increase without proportional elongation of the tip The infratip lobule becomes unnatu-rally thick with a decreased columellar-lobular ratio Fine tip modification is also difficult using these techniques, and the tip often looks sharp and pointed In addition, the piece
of cartilage on the distal implant is likely to become spicuous with time
con-In contrast, for the previously described technique using the stacked onlay graft, it is easy to elongate the tip Fine tip shaping is possible with additional carving and grafting Combining the wing grafts, it is more naturally smooth in shape, and there are no visibility or conspicuity problems of onlay grafts over time
Variant Techniques
The aforementioned procedures can be done using the endonasal approach However, generally this makes it more difficult to manipulate the grafts and to control the tension
on the tip skin For more visualization and more release
effect of the graft will abate with the collapse of columella
and membranous septum, requiring more amounts of
car-tilage, and the columellar-lobular ratio will deteriorate
Insertion of the Unified Graft and
Implant Hybrid
The unified graft and implant hybrid is inserted into the
dorsal pocket, and the profile is closely examined again
The surgeon has to examine the nose carefully,
temporar-ily closing the incision by pulling down the columellar flap,
because the profile can be changed due to the tension on the
skin Repeated carving may be required at this stage also
When the desired shape of the nose is finally obtained,
the onlay graft is fixed to the alar cartilages with sutures
The final fine modification of the tip and tip lobules is
done by carving and additional grafting A shield graft in
front of the graft or additional onlay grafts can be added
as necessary
Placement of the Wing Grafts
After obtaining a final tip shape, so-called wing grafts are
applied bilaterally on the lateral sides of the onlay graft
(Fig 2.12) The wing graft is shaped to assimilate the
lat-eral crura of the alar cartilages, to correspond with the
dome newly created by the stacked onlay graft Auricular
cartilage is best suited to this purpose because of its
natu-ral curvature The purpose of the wing graft is to prevent
the collapse or pinching deformity on the lateral sides of
the onlay graft Without the wing grafts, the tip is centrally
prominent only near the onlay graft, and laterally tip
lob-ules are collapsed and pinched The wing graft provides a
smooth transition from the tip to the lobules, softens the
margins of the onlay graft, and acts as a structural support
against soft tissue collapse The wing graft is also helpful in
Fig 2.11 The same length of the silicone implant as the stacked
onlay cartilage tip graft is cut out from the caudal end
Fig 2.12 The wing grafts are applied on both sides of the onlay
graft
Trang 39Closure and Splinting
For the final procedure, meticulous suture closure is done Then irrigation with antibiotic and antiseptic solutions is performed using a syringe after the closure
Taping is done to decrease the edema and to decrease the mobility of the implant and grafts Then a thermo-plastic splint is applied on the dorsum The splinting is important to immobilize the implant and to prevent edema and hematoma on the radix area in the immediate post-operative period The splint should be applied along the pre-marked vertical line of the augmentation The splint is maintained for at least 7 days
■ Key Technical Points
1 Designing an implant is the first and most critical step Based on the desired shape and individual anatomy, the implant should be carved correctly
2 The subperiosteal pocket is created The pocket should be symmetric and appropriately wide for the implant to be snugly placed inside and not be excessively mobile
3 For the septal extension graft, excessive tension on the graft is undesirable, especially when the septal cartilage is frail It provides a stable platform for the onlay tip graft, which is used for further tip projection and definition, commonly required in Asian patients
of tension, a marginal incision is extended medially over
the footplate to the nasal sill, and laterally to the piriform
ligaments
When the height difference between the tip and the
anterior septal angle is significant and the inclination of
lateral crura is considerable, a variant technique can be
used (Fig 2.13) The substantial tip-to-septum height
dif-ference and lateral crural inclination are commonly created
by the strong tip projection with the septal extension graft;
however, a considerable tip-to-septum height difference is
present even prior to surgery in some patients In this
situ-ation, the distal implant is carved in a wedge shape with
appropriate thickness to fit in the cephalic divergence of
alar cartilages The implant may be sutured to the cephalic
margins of the alar cartilages
For some patients, only the low nasal bridge, not the
tip, is the problem and their concern Then only a correctly
carved implant according to the individual dorsal anatomy
will suffice The implant is inserted through the marginal
or intercartilaginous incision Inadequately narrow, small,
or asymmetric dorsal pockets will predispose to extrusion
For the symmetry of the dorsal pocket, bilateral incision
and dissection are recommended The distal end of the
implant is tapered to be paper thin to smoothly continue
to the cephalic portion of the alar cartilages An implant
of excessive length, in a small or asymmetric pocket, may
extrude, especially when the distal implant is in direct
con-tact with the incision site In this regard, marginal incision
is more appropriate for the alloplastic implantation With
the marginal incision, additional tip grafting or other tip
manipulations are also possible
Fig 2.13 (a,b) When the gap is significant between the tip and the anterior septal angle, the implant may be carved in a wedge shape
and suture fixed to the cephalic margins of the alar cartilages

Problems Caused by Inherent Physical Characteristics of Alloplastic Implants
Capsule Formation
In cases where complications such as contraction do not occur, the fibrous capsule prevents the implant from bond-ing with skin, prevents skin damage, and maintains the thickness of the skin and soft tissue to some degree On the other hand, the fibrous capsule has a side effect of making the area susceptible to infection by preventing antibiotics from effectively penetrating the area around the implant and by letting the silicone implant create dead space within the capsule as it moves inside
In certain situations, the capsule causes severe cations, most notably the contracted nose.6 Creation of an excessively thick and wide capsule and contraction is usu-ally caused by additional factors such as bacterial infection and excessive tissue damage
compli-Therefore, to avoid overproduction of capsules and its ensuing complications, the surgeon must take care to pre-vent inflammation or infection from occurring during or after surgery, while minimizing tissue damage and bleed-ing by surgery
Skin and Mucosal Damage
Stimulation of the skin, damage to skin and appendages, skin thinning, skin contraction, and telangiectasis are long-term complications The slight yet repetitive damage caused
by the solid implant can harm the mucous membrane and create recurring chronic inflammation, possibly by ascend-ing bacterial infection through small mucosal defects To minimize such physical damage from silicone implants, the implant should be of appropriate length and width, and it must be well fitted and immobile Additionally, using
a softer material for the implant can help reduce cal stimulation Suturing a layer of dermis or dermofat on the outer surface of the implant is helpful in thin-skinned patients or revision cases to decrease mechanical stimula-
physi-tion, and mobility and visibility of the implant (Fig 2.14).Calcification
When removing a long-seated implant, the surgeon may come across calcification of the implant A calcified implant forms a harder and rougher surface, increasing stimulation
to the overlying skin and letting the irregular surface show through the skin Calcification may worsen with time.7 Cal-cification also relates to mechanical stimulation and dam-age to surrounding tissue
4 The pre-carved implant is inserted in the pocket
and the dorsal profile is carefully checked Repeated
carving may be necessary Using the distal implant
as a dummy for the tip augmentation allows
the amount of tip projection and rotation to be
estimated
5 The onlay graft is prepared It is commonly
stacked in multiple layers for sufficient tip
projection The same length as the onlay graft is
excised from the distal implant The onlay graft is
sutured to the cut end of the implant
6 The wing graft is prepared mimicking the lateral
crus It is placed on both sides of the onlay graft to
prevent the pinching deformity of tip lobules, to
decrease the conspicuity of the onlay graft
7 Further fine tip shaping is achieved by delicate
carving and the use of additional onlay or shield
grafts
8 Meticulous closure and irrigation using antibiotic
and antiseptic solutions are done Use of a
compressive dressing with a thermoplastic splint is
important to immobilize the implant and to prevent
edema and hematoma
■ Complications and
Their Management
Negative reactions toward alloplastic implants for
rhino-plasty were common in the Western part of the world This
may stem from experience with injectable materials such
as paraffin oil, liquid silicone, and early implants of
exces-sive size.5 Interestingly, recent research shows much lower
complication rates from silicone implants compared with
reports published in the 1960s and 1970s These changes
are thought to be due to improvements in implant design,
conservative surgical techniques, physicians having more
experience, and use of softer silicone Many physicians in
Asia perceive the complication rates of silicone implants
as acceptable, in part due to more experience with
rhi-noplasty using silicone implants compared with Western
physicians
Complications from silicone implants can be largely
grouped into two categories, those caused by inherent traits
of silicone itself and those resulting from the surgeon’s
technical or judgmental errors For a successful surgical
result, it is essential to minimize the inevitable problems
from inherent physical characteristics of the material and
to make efforts to reduce technical and judgment errors.5
Common complications, such as deviation, tip skin
problems, and infection, are more frequently related to
technical errors that are avoidable, and less frequently to
the physical characteristics of the material itself
