Lipoplasty has a threefold target: aesthetics, functionality, and restoration But onlysurgeons properly trained in liposculpture may achieve this target Lipoplasty is a surgicaltechnique performed through mini-incisions Thin tools, a few millimeters in diameter, areused under tumescent local anesthesia Operations should be performed by surgeons whohave experience in this field, under the control of anesthetists or cardiologists specialized insurgical monitoring.

& DEFINITION

Some specialists define liposculpture as a technique for fat tissue extirpation using blunt

2 mm to 5 mm cannulae Suction may be carried out with 20 cc or 60 cc syringes or throughminicannulae (2–4 mm) with suction equipments (1 atm) The name ‘‘liposuction’’ is used forthe same technique carried out for fat removal using suction equipment with larger cannulae.Fournier said that ‘‘liposculpture is the technique that uses disposable syringes toaspirate localized fat deposits and, if necessary, reinject it where needed (19).’’

We personally believe that the term ‘‘lipoplasty’’ is all inclusive, and that the term

‘‘lipoplasty liposculpture’’ includes all surgical, medical, or rehabilitative therapeutic tices It is sheer nonsense to assume that results are guaranteed after surgical procedures.The lack of comprehensive treatments is precisely what caused dissatisfaction in mostpatients submitted to liposuction some years ago

prac-We define ‘‘lipofilling’’ as the method of reinjection at different locations of theadipose tissue previously extracted through liposculpture and subsequently washed withphysiologic salt solution to preserve adipocyte integrity (20)

We define autologous tissue ‘‘implanting’’ (‘‘autolipofilling’’) as the method thatemploys fat tissue extracted through liposculpture and submitted to adipocyte lysis Aftersubsequent decanting, it is possible to obtain a compact tissular extract corresponding tothe support structure of the adipocyte.

& FAT TISSUE VASCULARIZATION

It is important to recall adipose tissue vascularization There are three vascular networkslaid horizontally and separated by different structures within the space between themuscular aponeurosis and the capillary dermis

From deep to superficial levels, we may find:

& the musculoaponeurotic vascular network

& the superficial fascia vascular network

& the dermic subpapillary vascular network

There are also perforating vessels across the deep fatty tissues that have no tions They connect to the superficial fascia through communicating branches that constitute

ramifica-a wide network from which smramifica-all communicramifica-ating vessels emerge ramifica-and reramifica-ach the cramifica-apillramifica-ary mis for skin irrigation It has been demonstrated that the adipose tissue blood flow variesaccording to the nutritional status and body weight, and that it increases in fasting conditions

der-AREOLAR FAT

It is located on the superficial fascia and is crossed by small perforating vessels for skinirrigation It is adipose tissue affected by the liposclerosis process, causing the typical peaud’orange condition, related to deep skin layers At the abdominal wall level, the thicknessranges from 0.8 cm to 2.1 cm in slim individuals, and from 1.5 cm to 2.5 cm in obese indi-viduals It corresponds to a safety fascia that should be preserved during liposuction andliposculpture; hence, surgical operations should never alter it

DEEP FAT

Deep fat is located under the superficial fat, separated by the superficial fascia The biggestblood vessels and lymphatic vessels may be found at this level Fat excess, altering bodycontour and corresponding to different steatomeries, is located at this level, where fatmay suffer hypertrophy in the event of general weight increase Its thickness may rangefrom an average of 0.5 cm in normal individuals to 4 cm or 5 cm in obese individuals This

is the fatty tissue that should be removed through liposuction and liposculpture

It is important to remember that adipose tissue is not only a reserve tissue but alsohas an important hormonal function: autocrine regulation, paracrine regulation, andendocrine regulation (21)

& PATIENT SELECTION

Liposculpture sometimes may be carried out under local anesthesia and as an ambulatoryprocedure because of its characteristics as a less aggressive method A wide variety of

SURGICAL TREATMENT B: VASER 223

patients may be submitted to it In each case, the following rules should be observed inorder to prevent future complications or the patient’s disappointment:

& Liposculpture is a technique aimed at localized adiposity, but it is not a slimming nique Hence, patient selection as well as the study of body contours and steatomericareas is essential

tech-& No more than 3000 cc of tumescent anesthesia solution should be used

& Maximal dose of lidocaine should be 50 mg/kg

& A maximum of 3 L of fat should be extracted

& No more than 25% of the body surface should be treated

& Mega-liposculpture should be avoided If aspirating more than 5000 mL of fat, one shouldfollow the recommendations of the American Academy of Cosmetic Surgery (22,23)

& It is particularly indicated in patients showing good trophism and good cutaneouselasticity

& The technique should not be applied to patients with a history of blood dyscrasia; renal,hepatic, or cardiac affections; hypertension; diabetes; and those suspected of havingpsychic disorders

& Patients with general obesity showing clear signs of muscular or cutaneous flacciditymay be treated It must always be kept in mind that an association of methods will

be necessary in rehabilitation

PRESURGICAL VISIT

First the physician should have a long conversation with the patient to understand the realmotivation for the visit, the referral, the patient’s knowledge of the technique, and especiallythe expectations and fantasies about the results It is very important to ascertain what thepatient expects as the possible outcomes of the operation Then, the patient should beexamined naked to detect examination areas and get a general impression of body andproportions assess possible outcomes according to body harmony

The examination should be carried out with the patient in a standing position and indifferent decubitus positions In fact, we should remember that the fat tissue mass has itsown mobility and changes according to different positions

The patient should be required to contract different muscle groups in order todistinguish muscular flaccidity from ‘‘false cullote de cheval,’’ to differentiate rectusabdomicus dehiscence or flaccidity from swelled or dilated abdomen, and thus definethe appropriate indications and techniques

The history of previous treatments such as iontophoresis, electrolipolysis, andmesotherapy should be investigated, as well as all methods that might have changed fattytissue characteristics: drugs or other therapies such as ozone therapy or massotherapy Weshould examine skin quality and muscle group tonicity Then we must provide our impres-sion, suggest indications, and give advice on possible risks

In the event that intervention is possible or indicated, we should provide a brochurewith complete information on the methodology and techniques to be used, includingdetails on the anesthesia and possible sensations to be experienced by the patient duringthe operation We should explain the method in detail, how the fat is extracted, the instru-ments used, and the risks and possible outcomes of the intervention Two photographs ineach position should be taken with an instant camera One of each pair will be modified,

drawing different body contours in black ink to serve as a real estimate of the possibleoutcome according to our personal view and experience A digital camera and imageediting software may also be used, but it is advisable to warn the patient that the resultspredicted by computer are impossible to reproduce exactly.

Factors in determining safety of liposuction include:

& the number of areas treated

& volume of supranatant fat removed

& percent of body fat removed

& ratio of body weight to the weight of fat removed

& dosage (mg/kg) of lidocaine

& volume of intravascular fluid infused

& duration of surgical procedure

It should be remembered that in many cases there is a gap between the fantasies ofthe patient and the real medical possibilities This may lead to discontent, disappointment,and complaints, and also legal procedures The patient should be informed that immediateand late postoperative periods are not identical Specific care for each period and thepossible limitations in each should be remarked on

Once explanations are given, all elements should be assessed and the indicated nique described again If necessary, the patient may take some photographs home to come

tech-to a decision in private or with her family

In the event of a favorable decision, routine laboratory tests, protein and albumincontent (lidocaine carrier), coagulation tests, cardiovascular surgical risk assessment,and hepatitis and HIV tests should be required Other factors to be investigated includepossible allergies to substances—especially to anesthetic drugs and skin disinfectants—and history of previous surgery, type of incision, and formation of keloids

DETAILED PHYSICAL EXAMINATION

& abdomen: hernias, scars, and diastasis

& varicose veins and hemorrhage

Broad-spectrum antibiotics should be prescribed, such as ciprofloxacin 500 mg,

1 g/day for 5 days after the operation If necessary, an analgesic or a nonsteroidal inflammatory drug (diclofenac potassium) may also be prescribed

anti-Exercise and sports should be interrupted at least for 2 weeks, but the patient mustwalk every day after the liposculpture (1 mile per day the first week after the second day);and also avoid sun exposure of treated areas for approximately 15 days

Care during immediate and late postoperative periods is very important When plasty is finished, bimodal compression with absorbent pads is fundamental, because itcontributes to the patient’s comfort and to a uniform skin and cellular subcutaneous tissueretraction This is accompanied by adequate compression and a supporting binder After

lipo-24 hours, the pads are removed and replaced by a supporting noncompressive binder(hence allowing lymphatic precollector functioning) In case of lower limb surgery, thepatient should start wearing graduated compression stockings (15 mmHg) 1 week afterthe operation

Immediate physical therapy consists of manual lymphatic drainage, 1 and 3 MHzexternal ultrasound, and magnetotherapy for 1 week Then, subdermal therapy andcarboxytherapy are introduced or continued

& CONCLUSION

Safety is the state of being free from danger and exempt from harm The foremost ethicalprinciple of medicine is ‘‘primum non nocere’’—first, do no harm In lipoplasty, thisprinciple is paraphrased by the statement ‘‘excessive liposuction is unsafe and thereforeunethical.’’

In September 1976, report of the first revolutionary operation that allowed theremoval of fat while limiting trauma and scars was published: liposuction was born(25,26) This methodology underwent various evolutions (19,27–29), allowing it to be usedfor different pathologies (30–32) or for lymphedema, lipedema, or lipolymphedema (33,34).Localized adiposity means physiological or pathological accumulation of fat tissue

in a specific body area Lipodystrophy means a pathologic condition affecting the ing tissue as well as the subcutaneous adipose tissue, characterized by various circulatoryand metabolic damages

support-Essentially, we use liposculpture for any particular type of pathology such as lized adiposity, adipose cellulite, and adipose lipodystrophy

& LIPOPLASTY

Liposculpture or lipoplasty defines a surgical strategy of body contouring for withdrawingthe localized adiposity With this therapeutic strategy, the body can be shaped by decreas-ing the adipose tissue At the same time the microcirculation is enhanced, allowing bettervenous and lymphatic return, improving metabolism, decreasing interstitial toxicosis, andimproving venous and lymphatic drainage Lipoplasty uses various methodologies ofliposuction and lipolymphosuction

& LIPOLYMPHOSUCTION

The use of liposuction has already been adopted with success (35) in the traditionalmethod with the utilization of 3 to 4 mm cannulae linked to a mechanical suction pump.Surgery can be performed under local or general anesthesia, sucking up even small quan-tities of adipose tissue by the way of a moss-pointed cannula (Mercedes type) with one ortwo holes at the top Cannulae are connected to a device expressing a power of 0.8 atm In

a particular area, such as the ankle or knee, the canalization technique can be used; that is,the creation of channels under the skin using small cannulae (diameter, 2–4 mm) This isperformed under local anesthesia through 2 or 3 mm incisions

Cannulae are not connected to a suction device; it is only the movement of the nula that induces the cellular disruption and channel formation The adipocyte disruption

can-is not induced by suction but essentially by the backward–forward motion of thecannula The created channels will help the adhesion of subcutaneous tissue to skin.The adipocyte contains collagen Thus, its disruption leads to collagen exposure intothe extracellular matrix, which is useful in the postoperative healing phase

With the introduction of ultrasound-assisted liposcultpure and the patented vibro-assisted

the reduction of interstitial pressure due to the adipocyte decrease is characterized by animprovement in microcirculation (arterial and lymphovenular) and tissue metabolism.The reduction in adipocyte number and size prevents the evolution of the adiposetissue and lipodystrophic pathology A consequence of adipocyte reduction is the systemicslimming and improvement of systemic metabolism related to the improvement in insulin

rehabilitation postsurgery phase An important application for liposuction is also thetreatment of lymphedema and particularly, lipolymphedema Lipolymphosuction allowsthe reduction of lymphedema and can be performed on the ankle, knee, and/or calf

& THE VIBRO-ASSISTED METHOD

The vibratory pneumo-assisted liposculpture (also called reciprocal automatic liposculpture

300 g device linked-to compressed air from the surgery room or a nitrogen bottle, and to

a 2 to 3 mm cannula connected to a vacuum device The PAD100-Microaire system allowsvibrations of the cannula tip, 2 mm transversely and 4 mm vertically, inducing rupture

and homogenization of fat, which is simultaneously aspirated Heat production and lymphatic tissue trauma are avoided because backward–forward motions are not necessary

veno-as in traditional liposuction; a little movement is sufficient Such a method, with a 1.8 to2.4 mm cannula, is used in the treatment of lymphedema and lipolymphedema,particularly at the level of ankle, calf, or arm This methodology is extremely useful givenits easy use and its rare side effects (38,39)

Bircoll, in 1982, first reported the use of autologous fat from liposuction for ing and filling defects (41) Of the wide variety of injection methods aimed at enlarging thevolume of soft tissues of the face and the body offered by specialists over the last decade,lipofilling attracts the ever-growing attention of aesthetic surgeons and dermatologists allover the world.

contour-Adipose tissue is the main energy store of our body and is associated with severalhormone receptors Autologous fat is thus an important source of material to fill lackingareas (42) It is also a strong stimulus for restructuring and metabolic regeneration Anautologous fat graft is always followed by a noticeable improvement in trophism andskin conditions Following the work of Giorgio Fisher, Pierre Fournier, Y.G Illouz,Sydney Coleman, Chajchir Abel, Newman Julius, and Roger Amar, we know today theimportance of fat transfer and lipoinjections (20,41,43–46)

Regarding the classical variants, they consist of obtaining fat by means of liposuctionwith thin cannulae, separation of fat from the ballast by centrifugation or washing with

or without a special solution, and administration of this fatty suspension under the skin or

into the muscle by means of a thick-diameter injection needle or a blunt cannula Methods forpreserving the obtained adipose implant, aimed at delayed additional use, are also proposed.

Our own experience confirms these conclusions: fat tissue may be successfully planted in depressions derived from liposuction, heat, or trauma, in order to restore anaesthetic contour and stimulate tissue restructuring

reim-Indications are:

& smoothing of facial wrinkles and fold,

& improvement of the congenital contours of the face and body, as well as those induced

by involutional alterations and soft-tissue ptosis, and

& removal of individual defects such as cicatrices following acne, hypotrophy of matic and postoperative scars, leveling of roughness after a failed liposuction, as well asthose induced by the so-called cellulite

posttrau-We infiltrate tissues with a solution of any known local anesthetic without othercomponents that may influence the cellular membrane of adipose cells (e.g., 0.1% lidocainesolution)

The volume of the administered solution should be two to four times as large as inthe traditional liposuction It is very important to administer the solution suprafascially,under the fatty layer from which fat procurement occurs

Doing so provides not only anesthesia, but also pushes the fat closer to the skin andits packing, thus making it possible, with the help of the cannula, to easily obtain the fattyimplant in the form of a pole with minimal injury to the adipocytes, because there is nomechanical, toxic, or osmotic effect In addition, the blood vessels are compressed, withthe lumen decreasing and practically no bleeding

Then, through a 5 mm or smaller cutaneous cut in a barely visible place, the donor fattytissue is taken into a 20 or 50 mL syringe by means of a cannula with reciprocating movement.However, to treat small facial wrinkles and striae, the collagenous and membranousportion may be used after centrifugation and sedimentation In other words, tissue itself

is used as a collagen or hyaluronic acid implant Association of the tissue with hyaluronic

acid itself may be useful since fat implants potentiate the hydrophilic action of this acid,causing an enduring physiological edema (47,48).

Careful attention should be paid to sterilization and to the technique for collectingand reimplanting adipose tissue Excessive tissue trauma should be avoided and careshould be taken to prevent potentially dangerous infections Despite its simplicity, lipofill-ing is a surgical operation that requires an accurate technique The administration ofantibiotics is recommended by some to prevent any chance of infection

be solved through small and early surgical interventions We refer, for example, to smallmedial thigh liftings carried out through vertical incisions on the pubis that enable skinrotation, thus reducing tissue excess in the medial thigh Limited abdomen miniliftings(inferior partial abdominoplasty) may also be useful since they enable cutaneous stratumrepositioning after liposuction The same is true for soft gluteal lifting, which restores loosetissues to their original position and improves the cellulite pathology at the back of thethigh, thus offering an image of a longer and slender limb plus more tonic and higher glutei.

& LIPOSHIFTING

Internal fat mobilization or liposhifting has proved to be an excellent method for the rection of postliposuction imperfections as well as for the redistribution of unaesthetic fatcumulus Blugerman has introduced a new instrument that facilitates the production of fatmicrografts in perfect condition to be internally moved to the area to be filled Internallipomobilization reduces fat trauma during suction and injection and also prevents contactwith air, reducing the risk of dehydration and contamination The new instrument, in its

available in three different models for use in different body areas
