PATIENTS AND METHODS
We prospectively evaluated all female patients who
voluntarily sought to improve the contour of the trunk
and hips via liposuction from July of 2011 to July of
2015 at Al manar clinic , Kuwait.
Laboratorial analyses were performed preoperatively in
all patients and included determination of hemoglobin,
hematocrit, prothrombin time, partial thromboplastin
time, glucose, urea, creatinine, Patients were advised to
stop oral contraceptive pills for 30 days and acetyl
salicylic acid for 7 days before surgery.
In patients older than 45 years of age or who presented
significant medical history, a complete medical
evaluation, including a resting electrocardiogram, was
performed.
Patients were followed clinically, and data were
collected regarding their preoperative and postoperative
course through photographs, patients’ subjective level of
satisfaction with the procedure, and complications. In all
patients, the results were evaluated with preoperative and
postoperative photographs. The assessment considered
patients’ level of satisfaction regarding their waist and
buttocks using a scale of 1 to 4 (1, poor outcome; 4,
excellent improvement).
Surgical Technique
Markings all patients were performed with the patient in
standing position.
Most of the patients the procedure were done under
general anaesthesia (90%) and the rest under spinal
anaesthesia upon the patient request.
Antibiotic given the patient with induction of
anaesthesia.
Tumescent infiltration of the fat tissue undergoing

ABSTRACT
Background: Anatomical features that make the buttocks attractive include adequate volume, projection, and a
defined infragluteal fold. simple and reproducible surgical technique for gluteal shaping and augmentation with
autologous fat is needed. The female waist-hip ratio of around 0.7 is reachable through liposuction and gluteal fat
grafting. The authors evaluated the reliability of this technique. Methods: Prospective evaluation was performed of
all female patients subjected to gluteoplasty with autologous fat tissue between July of 2011 and July of 2015
without a weight change greater than 10 percent during follow-up. Results were evaluated through photographs.
The degree of satisfaction (patient and surgeon) was assessed on a scale of 1 (poor outcome) to 4 (excellent
improvement), and agreement was measured by Kappa statistics. The technique involved epidural anesthesia,
tumescent infiltration, liposuction around the buttocks, fat decantation, and grafting with retrograde injection in
different planes. Results: A total of 200 patients were included. Patient age ranged between 22 and 60 years (mean,
33 years). The preoperative body mass index was between 19 and 31.6 kg/m2 (mean, 24.8 kg/m2). The volume
grafted to the buttocks ranged between 350 and 1000 cc (mean, 700 cc). There were no medical complications.
Conclusions: This gluteoplasty technique is simple and inexpensive, with minimal morbidity and excellent results.
A good result depends on harmoniously combining fat elimination by liposuction and fat grafting for buttocks
sculpting, with lasting results.

single area to prevent graft necrosis, and re-
accommodating eventual lumps of fat by massaging the
gluteal surface. First, we injected superficially to
improve the shape of the buttocks, from lateral to center.
Later, we injected deeper toward the gluteal muscle to
expand and augment its volume, giving projection but
avoiding overcorrection to obtain the desired contour at
the end of the surgery.
No drains were used.
Having the patient sit and sleep in the supine position in
the recovery room. Patients were also instructed to wear
an elastic compression garment for 2 months
postoperatively and start lymphatic drainage from the
first week after surgery, except in grafted areas. Patients
were instructed to take in about 4 liters of liquid per day
to avoid dehydration.
RESULTS
During the study period, 200 patients met the inclusion
and exclusion criteria and were operated on. All of them
were women. The age ranged between 22 and 60 years
(mean, 33 years). The body mass index at the time of
surgery ranged between 19 and 31.6 kg/m2 (mean, 24.8
kg/m2). The total volume grafted in each gluteal region
ranged between 350 and 1000 ml (mean, 700 ml) .
In the sample of patients evaluated, there were no
medical complications or postoperative complications
within the period evaluated. There were no cases of
infection.

DISCUSSION
Buttock contour surgery includes a wide variety of
procedures performed in various ways. Pitanguy4 and
Regnault et al.[5] improved the gluteal appearance by
resecting tissue from the trochanteric region and gluteal
fold. Gonzalez-Ulloa[6] and Lockwood[7] obtained a
better shape by lifting the whole gluteal region,
achieving substantial improvement but creating large and
visible scars.[4,7]
Power-assisted gluteal augmentation with autologous fat
is an efficient, safe, and reproducible procedure that
produces an aesthetically pleasing gluteal projection and
contour. 36
With the development of implants, several authors have
obtained good results with this technique.[810]
Undoubtedly, the use of gluteal implants is an advance
because they provide an adequate volume to the contour
of the region with minimal scars. However, the implants
have the disadvantages of cost, diminished durability
compared with breast implants,[11] and complication
incidence reaching up to 38.1percent in a multicenter
review of experienced gluteal augmentation surgeons.[12]
Many patients have an aversion to the use of foreign
material in their bodies. Moreover, implants do not allow
treating different parts of the buttocks according to each
patient need.
After the introduction of liposuction, a new
alternative[13,14] became available for the treatment of
body contours. Illouz himself, the creator of
liposuction,15 used fat as a graft to correct liposuction
deformities in a patient in 1984.[16] The first report of
successful fat grafting to the buttocks was in 1986 by
Gonzalez and Spina,[17] along with the development of
the first sterile device to accumulate the fat to be grafted.
The authors stressed the importance of injecting the fat in
different levels, avoiding large collections and using
cannulas between 1 and 3 mm. Since then, this procedure
has gained popularity around the globe,[18,19] with several
authors publishing classifications and treatment
strategies,[2,20,21] corroborated by the evidence of fat
survival in long-term monitoring studies.[2226]
Therefore, this procedure has been used to improve the
contour of the buttocks, and when needed, the projection
of the buttocks has been achieved without implants.
Considering the wishes of our patients and using the
principle of fat removal where it is in excess and
injection where it is needed, we decided to improve the
contour of the buttocks by a combination of two surgical
procedures that have given excellent results in plastic
surgery: lipoinjection and liposuction. Liposuction has
been considered the best choice for body
contouring.[15,27,28]
We obtained favorable results in patients using a
combination of both techniques. More than 90 percent of
our patients felt satisfied and showed improvement in
photographs, as determined by postoperative evaluation
by surgeons and patients. Two patients complained of
excess volume in lateral hips and underwent revision
surgery. Given this complaint, we have since started to
draw a line laterally, dividing anterior and posterior hip
and avoiding the injection of fat anterior to this line,
which has led to no more complaints about it. Notably,
we had no complaints regarding waist results.
The excess fat in the lumbosacral region is one of the
basic factors that must be corrected to achieve a proper
gluteal shape. For this reason, it was necessary to
perform liposuction in this area in all patients.
Liposuction of the subgluteal and saddlebag regions was
necessary in most patients, but not all of them. About 10
percent of the patients were thin (body mass index <20.0
kg/m2) and improved with a graft of less than 240 ml in
each buttock, later becoming satisfied, probably because
of a more realistic expectation built during preoperative
consultation. There was no relationship between the
volume injected and the satisfaction of patients or
surgical team. Of note, patients gave lower scores to
preoperative photographs than surgeons but higher
scores in the postoperative evaluation. Perhaps this
observation was attributable to a more objective analysis
by the surgeons, who showed a nearly perfect
postoperative agreement (K = 0.896/0.896), because they
are devoid of the emotional issues involved in patients’
assessments. Despite this difference, the Kappa analysis
showed that the postoperative agreement between
patients and surgeons was higher with regard to buttocks.
Regarding the prevention of complications, the amount
of fat and where it is infiltrated are two of the variables
to be considered to prevent local reaction and fat
necrosis.
According to Carpaneda’s principle,[29] in which the fat
graft survives up to 1.5 mm in radius, we used only 3-
mm or thinner cannulas to inject. Fat embolism
syndrome did not occur in any of our cases, but it is an
entity that deserves special attention because its
occurrence is not explained solely by fat grafting and has
been reported even after liposuction of smaller volumes
in sole surgical procedures.3032 The relationship of
multiple factors in the occurrence of this syndrome
warrants additional studies aimed to clarify its causes
during liposuction.
There are important aspects about the surgical technique
that are essential for good results. Liposuction with the
tumescent technique allows the surgeon to suction the fat
needed to achieve a good body contouring despite the
aspirated volume, which represents a limiting factor.[33
35] Likewise, the tumescent technique allows the
aspiration of very clean fat. We had no need for
additional procedures to clean the fat tissue, as other
authors have described.[2325] Letting the fat rest for a
while allows us to get clean fat for infiltration.

Infiltration is always made at the top of the gluteus
medius in an oval or circular pattern, depending on each
patient. The infiltration of the upper region works by
elevating the buttocks. The grafting of fat in different
planes and in various directions ensures symmetrical
results. Furthermore, using a continuous movement of
the syringe during the infiltration of fat and in different
planes prevents fat necrosis and accumulation of large
amounts of fat in one area. By applying these principles,
our complications have decreased, and the results have
improved considerably over time.
The improvement that can be achieved with the
combined technique of liposuction and fat grafting
depends on the amount of fat that can be removed from
adjacent areas of the buttocks and the amount of volume
that is needed in the gluteal region. When more fat is
aspirated, the result is more evident. For this reason, the
best results are obtained when the required increase is
less than 460 cc. We avoid grafting large volumes (>600
cc) because they give the buttocks an unnatural
appearance, with a ―balloon‖ shape, which leads fading
of the cosmetically nice curves related to it.[2,21]
Although we cannot objectively and precisely measure
the survival of injected fat, this technique is simple and
low cost, with minimal morbidity and an excellent result.
The gluteal shape obtained after prolonged follow-up is
satisfactory and demonstrates a significant survival of the
fat tissue over a long period of time. Good results depend
not on a large increase of the buttocks but on the
combination of two procedures used in a harmonious
manner to give the patient an ideal body contour by
removing fat deposits with liposuction and the
application of fat where it is needed.
CONCLUSIONS
This buttock augmentation technique is simple and
inexpensive, with minimal morbidity and excellent long-
term patient satisfaction. It is important to note that a
good result depends not on a lot of fat infiltration but on
the harmonious combining of the two surgical
proceduresthe elimination of fat by liposuction and fat
grafting for buttock sculptingfor lasting results.

Chapter
The unprecedented boom in demand for gluteal reshaping surgery has allowed for rapid technological innovation in plastic surgery and body-contouring surgery. The overall aim is to provide aesthetically pleasing outcomes, paired with safe surgery and a reduction of perioperative complications. It is therefore important that the surgeon who embarks in these reconstructive procedures is not only knowledgeable of gluteal anatomy but also versed in surgical technique. Surgeon experience, consistency, and frequency of procedure performance are of utmost importance when it comes to performing safe gluteal reshaping surgery. This chapter explores these principles with a special focus on the innovative technique of expansion vibration lipofilling (EVL) for large-volume autologous fat transfer in gluteal contouring and augmentation. EVL offers cutting-edge technology and with the use of appropriate technique outstandingly feminine gluteal reshaping outcomes.KeywordsButtock contouringGluteal augmentationReconstructive surgeryAutologous fat graftingLipectomyLipofillingHip-to-waist ratioCosmetic techniquesFeminization

Background: A simple and reproducible surgical technique for gluteal shaping and augmentation with autologous fat is needed. Objectives: The authors describe a novel approach to large-volume gluteal augmentation that combines power-assisted liposculpting and fat harvesting of the zones around the buttock with autologous fat transfer. Methods: One hundred ten patients who underwent gluteal augmentation were evaluated in a prospective study. Liposculpting and fat harvesting were performed with power-assisted liposuction. Fat then was transferred to the gluteal region with simultaneous power-assisted vibration and tunnelization. A questionnaire to assess patient satisfaction was administered at 6 months postoperatively. Results: The mean body mass index of the patients was 30 kg/m(2) (range, 26-36 kg/m(2)). Liposuction volumes ranged from 1400 to 5000 mL, and injection volumes ranged from 300 to 900 mL per side for each session. Operating times ranged from 60 to 120 minutes. Patients were monitored for an average of 20 months (range 12-48 months). Complications included a burning sensation in 5 of 110 patients (4.5%), persistent swelling in the lower back in 3 patients (2.7%), and a mild infection in 1 patient (0.9%). Conclusions: Power-assisted gluteal augmentation with autologous fat is an efficient, safe, and reproducible procedure that produces an aesthetically pleasing gluteal projection and contour. Level of evidence: 4 Therapeutic.

INTRODUÇÃO: Nos últimos 3 anos, o aumento da procura pela gluteoplastia cresceu em 20% no Brasil. Apesar de ser pergunta frequente nos consultórios de cirurgia plástica, não existem dados na literatura sobre a durabilidade da prótese. O objetivo deste trabalho é avaliar o tempo médio de duração do implante de silicone para gluteoplastia. MÉTODO: Estudo retrospectivo observacional, no qual foram revisados 380 prontuários para obtenção dos dados idade, data de inclusão da prótese e data da reoperação. Foi calculado o tempo médio entre a primeira cirurgia para inclusão do implante e a reoperação para troca ou retirada da prótese. RESULTADOS: Dos 380 casos avaliados, 70 pacientes foram reoperados pelo autor sênior, apenas 2,8% dos casos apresentaram prótese íntegra durante a reoperação e os demais estavam com a prótese rota. A prótese do glúteo direito estava rompida em 100% dos casos e a do glúteo esquerdo, em 80%. CONCLUSÕES: O implante glúteo apresenta tempo de vida útil inferior ao do implante de mama, apesar de ser fabricado com o mesmo material. Esse fato decorre da maior exposição da prótese à tensão por compressão, o que explica sua menor durabilidade estar associada ao estilo de vida e à profissão da paciente.

"Lipexeresis" is a successful method for removing excessive local fatty tissue from the female body for pathologic or for aesthetic reasons. In contrast to other surgical operations, it is highly important that no disturbing scars remain. Except for two patients who underwent operation on the lower leg, with more serious complications, the results have been very encouraging.

: Enhancement of buttock volume with gluteal silicone implants has been performed by surgeons for over 30 years, but no studies have examined complication rates or outcomes of more than single-surgeon experiences. Numerous technical differences in how gluteal augmentation surgery with implants is performed also exist, and to date, surgeon preferences for implant plane, incisional access, implant type, and drain use have not been quantified. : A 10-question survey was sent to 83 targeted members of the American Society of Plastic Surgeons requesting information about number of cases performed, duration of surgeon experience, implant placement plane and incisional access, implant type, length of typical surgery, use of drains and antibiotic irrigation solution, surgeon satisfaction and surgeon assessment of patient satisfaction, and number of complications experienced. : Nineteen respondents (25 percent response rate) provided data on 2226 patients. Thirteen respondents (68.4 percent) favored the intramuscular plane of dissection over the subfascial plane. Preference for incisional access was nearly equally divided between a single incision in the gluteal cleft (10 respondents) and two incisions separated within the cleft (nine respondents). The total number of complications reported was 848 (38.1 percent). : Gluteal augmentation with silicone implants has gained popularity in the last decade. Despite this, no previous studies have examined multisurgeon experiences with this procedure to determine complication rates or surgeon technical preferences. The authors present data from a survey sent to experienced gluteal augmentation surgeons. Advances in technique and implant options are needed to improve complication rates experienced with this procedure.

Fat infiltration for gluteal contour improvement is a procedure that is gaining more advocates. This has caused the application technique and the amount of fat infiltrated to change over time. The authors present their buttocks fat grafting technique evolution that occurred over a 14-year period. From April of 1995 to March of 2009, 789 patients underwent liposuction and buttocks fat grafting. Patients were divided into three stages according to chronologic evolution and amount of fat infiltrated. During the first period (April of 1995 to January of 2004), 120 to 320 cc of fat was infiltrated in the upper gluteal area. During the second period (February of 2004 to February of 2006), 210 to 460 cc of fat was infiltrated in the upper and lower gluteal area. In the third period (March of 2006 to March of 2009), 220 to 1160 cc of fat was infiltrated in the aforementioned areas and in the trochanteric and subgluteal areas. Complications such as fat necrosis, gluteal erythema, infection, and fat embolism syndrome were more frequent and serious in the first stage, despite the authors having infiltrated smaller volumes. Increasing the volume of fat infiltration in the buttocks has resulted in better contour results in the whole area, and distribution of that larger volume in more extensive areas and in different layers has decreased the index and number of complications. Therefore, to obtain better aesthetic results, it is necessary to keep in mind that these larger amounts must be distributed in larger areas and layers to decrease postsurgical morbidity.

The history of gluteoplasty augmentation includes only a few reported clinical series. We report our experience in performing gluteal augmentation using an intramuscular technique in 160 cases over 15 years. We also establish guidelines for performing this procedure. All patients were women, ranging in age from 18 to 65 years, who underwent intramuscular gluteoplasty between June 1986 and September 2000. Of these patients, 104 (65%) received textured silicone gel implants and 56 (35%) received textured silicone elastomer implants. Thirty patients (18.7%) received 250-cc implants, 100 (62.5%) received 300-cc implants, and 30 (18.5%) received 350-cc implants. Satisfactory aesthetic results were obtained in 144 of 160 patients (90%). Complications presented in 16 patients (10%), including seroma in 7 patients (4%), asymmetry in 4 patients (2.66%), capsular contracture in 3 patients (2% ), overcorrection in 1 patient (0.66%), and rupture of the implant in 1 patient (0.66% ). Intramuscular gluteal augmentation offers long-term, predictable, and pleasing aesthetic results with a low incidence of major complications. (Aesthetic Surg J 2003;23:86-91.).
