Trang 2PREOPERATIVE CONSIDERATIONS
Anatomy
Periorbital volume restoration is of primary importance
in creating an appropriately full frame around the eye
The most important component of the ‘frame’ is the
inferior orbital rim Reviewing photographs of models
allows us to understand this aesthetic ideal.Variations in
the upper periorbital frame exist, with the most
com-mon appearance being a full brow with a few
millime-ters of the upper lid skin visible (Fig 18.3) Some very
attractive individuals have relatively sculpted and
hol-lowed brow/upper eyelid complexes, but uniformly
every young beautiful face has a full lower eyelid that
blends seamlessly with a full cheek Again, review of an
individual’s old photographs will help determine what is
a natural appearance for the specific patient As already
mentioned, significant pseudoherniation of lower
orbital fat will benefit from selective reduction via a
transconjunctival blepharoplasty combined with
con-current filling of the inferior orbital rim by autologous
fat transfer Similarly, a truly deflated and hanging upper
eyelid would be best approached with conservative
removal of redundant skin, with some degree of fat
transfer into the brow (Fig 18.4)
The cheek is an extension of the lower frame of the eye and is a vital component of a youthul heart-shaped face The cheek can be divided into anterior and lateral components With advancing age, the anterior cheek, which develops the most significant volume loss along the malar septum, is a primary target for fat transfer The lateral cheek, when restored, should reveal the lustrous highlight that is associated with a convex youthful shape (Fig 18.5) Often, the buccal region must be volume-enhanced,
as it becomes relatively hollow after augmentation of the malar region However, care must be taken to avoid overfilling this area if the patient desires the more sculpted look that manifests in one’s 30s as opposed to the fuller oval shape of someone in their early 20s
Placement of fat into the precanine fossa and nasolabial fold is not so much intended to efface the linear depression but rather to provide an improved contour from the newly augmented cheek to the upper lip.We believe that any one of a number of avail-able dermal fillers is more useful for elimination of the nasolabial and labiomandibular folds Similarly, lip augmentation with fat grafting only yields subtle results after considerable and protracted postoperative edema

of lid skin visible and a lower eyelid that transitions seamlessly into a full cheek

Trang 3Facial fat grafting of the lower face is centered on
finishing the lower point of the triangle of a youthful
countenance.Therefore, the focus of fat grafting along
the lower face is concentrated in the prejowl sulcus,
anterior chin, labiomental sulcus, and labiomandibular
depression Augmentation of the lateral mandible
can-not be undertaken concurrently with a facelift due to
undermining of the skin in this portion of the face
Patients with mild jowling or prejowl volume loss can
achieve a very good restoration of the jawline with fat
grafting alone In contrast, we have found that it is
dif-ficult to truly attain a straightened jawline with facial
fat grafting alone in patients who have a heavy jowl and
that, for optimal patient and surgeon satisfaction, a
facelift should be incorporated for these patients
However, augmentation of the prejowl with fat
graft-ing can enhance the result of any facelift, and is
incor-porated into most of our rhytidectomies (Fig 18.6)
Consultation
As with any cosmetic consultation, the ultimate goal is
to establish aesthetic objectives for surgical and/or nonsurgical intervention mutually agreed between the surgeon and the prospective patient Besides the stan-dard psychological, emotional, and aesthetic consider-ations that are part of every initial patient encounter, the surgeon must establish aesthetic goals, realistic expectations, and an understanding of the potential recovery period that relate specifically to fat grafting These unique considerations will be elaborated in this section, and can be incorporated into the framework
of a standard consultation
Often during the consultation, the patient must be refocused on what truly gives them an aging appear-ance Women, in particular, focus on fine lines that typically achieve disproportionate importance when

Trang 5viewed with a magnifying mirror and bright
illumi-nation during makeup application The consultation
aims to recalibrate their thinking to evaluate their
face the way other people see them from
conversa-tional distances Addiconversa-tionally, we point out that they
primarily see themselves only in frontal view in a
mirror, whereas in the real world they are usually
seen at an oblique angle.To help the patient
appreci-ate this, we will often take digital images of the
patient and review these with them Volume and
shape are emphasized over fine wrinkles and minor
cutaneous blemishes, which, to reiterate, are not
truly ameliorated with facial fat grafting Digital
imaging of possible results plays a very limited role
in the discussion of facial fat grafting It is almost
impossible to demonstrate the benefits of fat grafting
with digital morphing analysis, since the technology
is two-dimensional and the operative intervention
is three-dimensional Instead, use of a catalog of
before-and-after photographs of patients whom the
surgeon has taken care of is perhaps the most
effec-tive way of demonstrating to the patient the benefits
of fat grafting
Showing patients how they may look at 1 week, 2
weeks, 1 month, etc after surgery provides the most
useful information about potential recovery time
Most often, when an individual views other patients
during this early recovery period, he or she may not
perceive that they look very swollen, just better
However, it is important to emphasize that most of
these patients were uncomfortable with the way they
looked during the first 2–3 weeks following surgery
These psychological details are helpful to discuss with
each patient in the preoperative setting Use of old
photographs can also be very enlightening both for the
patient and for the surgeon.The patient should readily
grasp the volume changes associated with aging, and
the surgeon can better discuss with the patient what
aesthetic changes will be most beneficial toward
reestablishing a youthful appearance.As already stated,
many women do not like the fullness, often referred to
as ‘baby fat’, that is prevalent in their teens and early
20s, but prefer the relative sculpted (but not yet
hollow) appearance of themselves in their late 20s to
early 30s
OPERATIVE TECHNIQUE Donor harvesting
For very thin individuals, it may be advisable to evalu-ate potential donor sites during a preoperative visit Generally speaking, most patients will be able to inform the surgeon where they have abundant fat For instance, men are predominately truncal-dominant, whereas women can either be truncal (abdomen/ waist) or extremity (inner or outer thigh) dominant For very thin individuals or those who have undergone extensive prior body liposuctioning, the lower back and triceps may be ideal reserves that remain for har-vesting Most commonly, the lower abdomen and inner thigh serve as excellent donor sites for fat harvesting if intraoperative patient repositioning is problematic
Before lower abdomen harvesting is undertaken, it
is imperative to inquire what abdominal procedures the patient has had in the past and to evaluate the dis-tribution of abdominal scars In order to ensure that the patient does not have an occult ventral or umbilical hernia, the surgeon should ask the patient to Valsalva in
a supine position with his or her head elevated for optimal evaluation Obviously, a hernia in the field of harvesting would preclude harvesting in that area Many aesthetic surgeons who are uncomfortable with body harvesting express trepidation about uninten-tional violation of the visceral cavity during harvesting This outcome is very unlikely, especially under con-scious sedation, given the thickness of the muscular fascia as well as the exquisite discomfort elicited when the fascia is even abraded with the harvesting cannula For the inner thigh, the surgeon must ensure that the cannula passes through a superficial fascial layer before fat harvesting can commence Superficial passage of the cannula is evident by the visibility of the cannula through the skin, which should be immediately cor-rected to avoid a potential contour deformity in the donor area
Although fat grafting can be undertaken with any level of anesthesia, we have found that intravenous sedation provides excellent pain control and patient compliance After the patient is adequately sedated,
Trang 6the donor area is infiltrated with 0.25% lidocaine with
1:400 000 epinephrine using a 20 cm3syringe
outfit-ted with a 22-gauge spinal needle (The mixture is
attained by combining 5 cm3 of 1% lidocaine and
1:100 000 epinephrine with 15 cm3of normal saline.)
If the patient is under oral sedation, then a higher
per-centage of lidocaine (0.5% lidocaine with 1:200 000
epinephrine) should be used to improve patient
com-fort (The mixture is attained by combining 10 cm3of
1% lidocaine and 1:100 000 epinephrine with 10 cm3
of normal saline.) When allocating the 20 cm3of local
anesthesia, the surgeon should aim to place 10 cm3in
the deep aspect of the fat pad (immediately above
the muscle/fascia) and 10 cm3 into the immediate
subcutaneous plane, leaving the bulk of the fat pad
untouched with anesthetic
After the patient has been sterilely prepped and
draped, a 16-gauge Nokor needle (or No.11
Bard–Parker blade) is used to make a stab incision for
entry of the harvesting cannula For lower abdominal
harvesting, the incision can be made inside the lower
aspect of the umbilicus or suprapubically, and for the
inner thigh, it can be made along the inguinal crease
Many different types of harvesting cannulas can be
used We prefer a 3 mm bullet-tipped cannula for
har-vesting (Fig 18.7) All harhar-vesting is undertaken with a
10 cm3syringe manually, i.e., without machine
assis-tance, using only 1–2 cm3of negative pressure on the
plunger A few technical pearls that can help the novice
surgeon undertake harvesting easily and effectively
should be enumerated First, the surgeon should
attempt to remain within the middle substance of the
fat pad Rippling of the skin with passage of the cannula
indicates that the cannula is too superficial.The surgeon
should always be cognizant of where the cannula tip
resides, as the tip is the active end where fat enters If
the cannula tip abrades the deep fascia or goes beyond
the anesthetized area, the patient can experience undue
and unnecessary discomfort As the surgeon continues
harvesting, the cannula should be retracted almost back
to the entry site before redirecting to the adjacent site
If the cannula tip is not withdrawn prior to directing it
to an adjacent site to continue harvesting, the surgeon
will effectively be harvesting in the same passage site,
not in a new area While harvesting, the nondominant
hand should stabilize the fat pad, not squeeze or deform the donor area, to prevent uneven harvesting and potential donor-site contour deformity.When harvest-ing, the surgeon should recall that usable fat will be about one half the harvest volume, e.g., each 10 cm3
syringe will yield approximately 5 cm3of viable fat
Processing the fat The next step is processing the fat.The 10 cm3syringes are placed in the centrifuge and spun for approximately 2–3 minutes at 2000 to 3000 rpm.This will sufficiently separate the unwanted blood, lidocaine, and lysed fat cells from viable fat cells Before centrifugation, each
10 cm3syringe must be outfitted with customized caps and plugs to ensure that the contents do not spill out during the centrifugation process It is imperative not to use the prepackaged plastic caps that fit onto the Luer-Lok side, as they will invariably become detached dur-ing centrifugation It should also be emphasized that the centrifuge should be able to accommodate either sterile individual sleeves that hold each syringe or, alterna-tively, an entire central rotary element that holds all of the syringes, which can be removed and sterilized After the fat has been centrifuged, the supranatant (from the plunger side), consisting of lysed fat cells, is poured off Only after removing the supranatant is the Luer-Lok cap removed and the infranatant drained A noncut 4×4 gauze (or cotton neuropaddy) is placed into the plunger side, making contact with the column
of fat in order to wick the remaining supranatant away After 5–10 minutes, the column of fat is then poured from the open plunger side of the 10 cm3syringes into the open plunger side of a 20 cm3Luer-Lok syringe The 20 cm3syringe should not be filled beyond the
15 cm3 mark When pouring the fat into the 20 cm3
syringe, the surgeon should attempt to keep any resid-ual bloody infranatant in the original 10 cm3syringe.A Luer-Lok transfer hub allows transfer of fat from the
20 cm3syringe into 1 cm3Luer-Lok syringes used for fat injection The plunger on the 1 cm3syringe should
be drawn all the way until it is actually removed from the syringe while filling the syringe with fat, so as to eliminate the air bubble that typically resides between
Trang 7the plunger and the end of the fat column.The plunger
is then returned to the 1.0 cm3 mark to maintain
accurate volume counts
Fat infiltration
The following general principles of technique will help
to optimize results and minimize problems The
pri-mary principle behind safe fat grafting, particularly
when learning the technique, is to ‘hit doubles’ rather
than strive for a ‘home run’ Placing too much fat into
any area, especially in the periorbital region, is very
difficult to correct, whereas placement of additional
fat can be easily and quickly undertaken in a second
session (see ‘Management of complications’ below)
Placement of fat is done only in small parcels
(0.03–0.05 cm3 per pass for sensitive areas and
0.1 cm3per pass in more forgiving zones) in order to
attain optimal fat cell survival by allowing maximal
contact of each particle with the surrounding tissue
and neighboring blood supply.The use of blunt
cannu-las (Fig 18.7) (Tulip Medical Inc., San Diego, CA;
Byron Medical Inc., Tucson, AZ; Miller Medical Inc.,
Mesa, AZ) allows for less traumatic insertion of fat,
resulting in less bruising and swelling.While injecting fat, the nondominant hand is used to palpate the underlying bony landmarks (to be discussed below) in order to guide the passage of the cannula in the correct depth and location Finally, as the cannula tip cannot be visualized, the surgeon must mentally envision the depth of the tip during the procedure We have divided the injection planes into three basic levels, which will be referred to throughout this section on infiltration technique, as deep (corresponding to the supraperiosteal level), medium (the musculofascial or deep subcutaneous level), and superficial (the superficial subcutaneous depth)
Recipient site anesthesia The three skin entry sites (A: midcheek; B: lateral can-thal; and C: posterior to the prejowl sulcus) are infil-trated with 1% lidocaine with 1:100 000 epinephrine (Fig 18.8).Then, appropriate facial regional blocks are performed, usually including the infraorbital, zygo-maticotemporal, zygomaticofacial, and supraorbital nerves An 18-gauge needle is used to create the three entry sites on each side of the face The same infiltra-tion cannula intended for fat infiltrainfiltra-tion is used to inject local anesthesia (1% lidocaine with 1:100 000 epinephrine) into the planned recipient sites in order
to minimize tissue trauma
Inferior orbital rim The inferior orbital rim is the area that requires special attention in terms of both total volume placed and tech-nique Fat grafting to the inferior orbital rim is done through an entry site on the cheek, which allows the fat
to be deposited perpendicular to the bony orbital rim
In our experience, a lateral-based entry point in which the cannula is passed parallel to the orbital rim con-tributes to an unacceptably high incidence of fibrotic fat bulges Generally speaking, for the beginning surgeon,
we advocate placement of 1 cm3of fat along the medial inferior orbital rim and 1 into the lateral inferior orbital rim The fat is injected into the deep (supraperiosteal) plane.The nondominant index finger is used to palpate the rim to confirm the appropriate cannula depth and to guard against injury to the globe (Figure 18.9) As the cannula tip is passed perpendicularly across the inferior orbital rim (about 1 mm in either direction), 0.05 cm3
of fat is layered per pass of the cannula Additional fat

Trang 8can be placed for more volume-depleted patients at a
medium depth Fat infiltration superficial to the
orbicu-laris oculi muscle is not recommended.The
supramus-cular plane in this region has no added advantage, and
has significant potential for contour irregularity.We
rec-ommend being conservative with volumes in this area
until the surgeon is comfortable with the technique
Even for the more experienced fat injector, we caution
against exceeding 4 cm3in the infraorbital rim at one
setting in order to minimize problems
Superior orbital rim/brow
The primary objective in filling the superior orbital
rim is to re-establish a youthful appearing lateral brow
convexity Filling a markedly hollow upper eyelid sulcus
is an advanced technique, lying beyond the scope of this chapter Placement of fat along the superior orbital rim can be undertaken easily from a lateral entry point and rapidly filled using 0.1 cm3per pass without difficulty or significant risk of contour deformity.The passage of the cannula should follow the plane of least resistance.The appearance of this area being overfilled may arise toward the end of augmentation – this should give rise to alarm,
as it will settle over time Generally, 2 cm3of fat begins
to restore the deflated lateral-brow convexity
Nasojugal groove The nasojugal groove is the triangular depression out-lined superiorly by the medial inferior orbital rim and medially by the nasal sidewall For the purposes of fat transfer, we make a distinction between the nasojugal groove and the tear trough The latter is distinguished
as the visible depression in the region of the medial orbital rim, which, depending on a patient’s particular anatomy, may or may not directly correlate with the bony nasojugal groove The nasojugal groove is gener-ally filled with 1 cm3 of fat, which can be placed quickly with 0.1 cm3per pass of the cannula
Anterior cheek The area of greatest volume loss in the anterior cheek
is usually along a linear depression running from superomedial to inferolateral, corresponding to the malar septum The anterior cheek is infiltrated from the lateral canthal entry point As the cannula passes through the anterior cheek, it is common to feel resis-tance from the malar septum.The primary areas of fat deposition in the anterior cheek are along the malar septum and anteromedial to it Caution should be taken to not overfill this region in men, as this may feminize the face In general, 3 cm3of fat are injected, with 0.1 cm3per pass.The surgeon should try to visu-alize the passage of the cannula from a deeper to a pro-gressively more superficial plane to distribute the fat cells more widely and thereby enhance the potential for adipocyte survival The volumes used can be increased as needed for more volume-depleted patients Anterior cheek volumes should be more conservative in males, where a fuller anterior cheek will tend to feminize the face

Trang 9Lateral cheek
The lateral cheek highlight is a very important youthful
landmark to restore Approached from the midcheek
entry point, the area overlying the lateral zygoma is augmented with 2–3 cm3of fat The injection can be tapered into the submalar region as needed The tech-nique of gradual progression from a deep to a superfi-cial plane and placement of 0.1 cm3per pass is the same
as that described for anterior cheek augmentation
Buccal Many women find the slight hollow of the buccal region that arises in their early 30s to be attractive
by creating a more sculpted appearance Progressive buccal volume loss will lend the appearance of poor health, and in women can also be masculinizing During a fat augmentation procedure, the addition of volume to the cheeks may create a relative buccal hol-lowing, which should be addressed The buccal area can be approached from multiple entry sites, including the midcheek or lateral canthal entry sites; alterna-tively, a separate lateral commissure entry site can be made for buccal access Filling can progress rapidly as above, with 0.1 cm3per pass in every tissue plane.The buccal area can sustain significant volume enhance-ment without deformity, e.g., 3–8 cm3per side
Precanine fossa/nasolabial fold
As mentioned above, the objective of filling the pre-canine fossa (the bony triangular depression deep to the superior limit of the nasolabial fold and adjacent
to the nasal ala) and the nasolabial fold is not to elimi-nate the fold but to provide improved transition from the augmented cheek to the augmented upper lip.The patient should be cognizant of this limitation so that realistic expectations are established preoperatively The precanine fossa is infiltrated in the deep supra-periosteal plane with approximately 2 cm3of fat The nasolabial fold can be augmented with 2–3 cm3of fat along multiple levels using 0.1 cm3per pass without significant risk of deformity.These areas are addressed from the midcheek entry point so the cannula will pass perpendicular to the nasolabial fold
Prejowl sulcus/anterior chin/labiomental sulcus/labiomandibular fold
The prejowl sulcus is perhaps the most important area
in the lower face to address with autologous fat trans-fer Placement of fat along the prejowl sulcus will not

to marked jowling, but will significantly enhance any
facelift result.The prejowl sulcus should be thought of
as a three-dimensional cylinder that runs along the
anterior and inferior borders of the mandible
Generally, 3 cm3of fat are placed using 0.1 cm3per pass
from an entry site just posterior to the prejowl sulcus,
typically about midway along the mandibular body.The
first 1 cm3is placed deeply along the anterior
madibu-lar border.The second 1 cm3is placed deeply along the
inferior mandibular border, and the third 1 cm3 is
placed at a medium-depth to transition between the
two In patients with a deeper sulcus, larger volumes
will be needed to obtain the desired result Additional
fat can be feathered into the anterior chin, labiomental
sulcus, and labiomandibular fold as needed It is
impor-tant to emphasize that the degree of variable resorption
of fat in the anterior chin leads to less predictable
results in terms of chin projection than can be achieved
with an implant Therefore, when the primary goal is
anterior chin projection, an alloplastic chin implant
is our preferred treatment option Nevertheless, fat
transfer to the anterior chin/mental sulcus region can
accentuate the beauty of a youthful face by restoring
the inferior apex of the ideal heart shape previously
discussed
POSTOPERATIVE CONSIDERATIONS
Postoperative care
At the end of the procedure, the patient does not
require any dressings, bandages, drains, or suture
clo-sures for the body or for the face Icing of all recipient
sites will help mitigate postoperative edema After the
first 48–72 hours, the patient may ice the recipient
areas as they would like Sleeping with the head
elevated for the first several days may also aid in
reduc-tion of edema Reducing dietary for the first several
weeks after surgery may also lessen edema.The patient
should refrain from strenuous activity so as not to
exacerbate and prolong edema unnecessarily The
patient can return to a modified exercise regimen after
the first week and should slowly progress toward a
full, standard program, verifying all the while that
edema does not worsen with that activity.There are no
restrictions on activity for harvested areas, except for not submerging the incisions for a week
Postoperatively, patients often complain of a dull ache and soreness in the donor areas that exceeds any dis-comfort felt in their face However, there may be some degree of tenderness and tightness in the face, particu-larly in the malar region Occasionally, patients can feel a flush sensation in the malar area during the first post-operative week, which can be ameliorated with icing Ecchymosis and edema are most pronounced over the first two postoperative weeks During the first week, the patient may appear grossly disfigured, which will be proportionate to the amount of fat transferred and the number and extent of concurrent rejuvenation procedures Ongoing changes will be evident postop-eratively for several months, and it should be empha-sized to the patient that what he or she is seeing is normal and expected due to the dissipation of edema Educating patients preoperatively and reviewing the expected changes postoperatively are helpful for the patient to have the appropriate understanding of the changes they are seeing as swelling subsides
Management of complications The area most susceptible to complications is the peri-orbital region.The conservative policy of fat enhance-ment (‘hitting doubles’) previously outlined should be followed so as to minimize the occurrence of prob-lems In order to correct a complication, the surgeon must correctly identify the problem This section will outline the unique types of problems that occur with fat grafting and how to treat each specific entity The types of complications can be classified as follows: lumps, bulges, overcorrection, and undercorrection
Lumps
A lump is a soft discrete contour deformity that arises when too much fat is transplanted to a specific locus or placed in an imprecise fashion Although steroid injec-tions have been attempted to manage this problem, they are generally not very effective An incision with direct removal of the offending lump often must be undertaken Although uncommon, visible lumps are most apt to occur along the inferior orbital rim If a lump from the region of the lower lid is to be
