Abstract
Background Gluteoplasty or gluteal augmentation is a popular cosmetic procedure that is used to improve the volume, shape, and contour of the buttocks. Objectives This bibliometric analysis aims to characterize emerging research trends and to assess the methodological quality of the highest impact gluteoplasty research. Methods The 100 most-cited publications in gluteoplasty were identified on Web of Science, across all available journal years (from Inception to August 2023). Study details, including the citation count, main content focus, and outcome measures, were extracted and tabulated from each publication. Oxford Centre for Evidence Based Medicine level of evidence (LOE) of each study was assessed. Results The 100 most-cited publications regarding gluteoplasty were cited by a total of 2375 publications. Citations per publication ranged from 5 to 176 (mean 23.75 ± 25.86), with the highest-cited study being authored by Simonacci, discussing autologous fat grafting (n = 176). Most publications were LOE 5 (n = 55), representative of the large number of case series and reports. The number of publications for LOE 1, 2, 3, and 4 was 1, 9, 13, and 22, respectively. The main content focus was "surgical technique" in 38 publications, followed by "outcomes" (n = 34) and "risk factors/prognosis" (n = 10). Patient-reported outcome measures (PROMs) were used in 20 publications, and 33 publications reported aesthetic outcome measures. Conclusions This analysis demonstrates a need for improvement in research methodologies regarding gluteoplasty research. This advancement would be facilitated by robust, high-quality research through randomized control trials and multicenter studies, as well as the further development of validated PROMs for gluteoplasty.

Aesthet Surg J 2024; 44:NP454-NP463. [PMID: 38563572 DOI: 10.1093/asj/sjae074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 03/17/2024] [Accepted: 03/25/2024] [Indexed: 04/04/2024] Open
Abstract
Liposuction is a surgical procedure used to remove localized excess adipose tissue. According to The Aesthetic Society's latest annual report, liposuction is the most commonly performed cosmetic procedure. Despite its popularity, the existing literature lacks a unified understanding of the risks associated with liposuction. The aim of this study was to measure complications of liposuction. A systematic review and meta-analysis was reported according to PRISMA guidelines and registered on the PROSPERO database (CRD42023471626). The primary outcome was overall complication rate. The absolute risk for individual complications was also assessed. From 2957 articles, 39 studies were selected for analysis. In total, 29,368 patients were included, with a mean age of 40.62 years and mean BMI of 26.36 kg/m2. Overall, the rate of any complication was 2.62 (95% CI, 1.78-3.84). The most common complication was contour deformity, with a prevalence of 2.35% (95% CI, 1.05%-5.16%). The prevalence of hyperpigmentation was 1.49% (95% CI, 1.12%-1.99%), seroma 0.65% (95% CI, 0.33%-1.24%), hematoma 0.27% (95% CI, 0.12%-0.60%), superficial burn 0.25% (95% CI, 0.17%-0.36%), allergic reaction 0.16% (95% CI, 0.050%-0.52%), skin necrosis 0.046% (95% CI, 0.013%-0.16%), generalized edema 0.041% (95% CI, 0.0051%-0.32%), infection 0.020% (95% CI, 0.010%-0.050%), venous thromboembolism 0.017% (95% CI, 0.0060%-0.053%), and local anesthesia toxicity 0.016% (95% CI, 0.0040%-0.064%). Liposuction is a safe procedure with low complications, of which contour deformity is the most common. Raising awareness of specific risks can enhance surgical outcomes and improve patient-physician understanding. LEVEL OF EVIDENCE: 3

Abstract
The shape and definition of the male buttock have been emphasized throughout time, as it represents masculinity, strength, health, and beauty across various cultures. Aesthetic Plastic Surgery in general has become more acceptable for men; thus, the demand for gluteal enhancement parallels this shift in social norms. Surgeons interested in such cases must first understand the aesthetic ideals and principles of gluteal shaping as it pertains to men. By using gluteal implants, fat transfer techniques, local tissue rearrangement principles, or a combination thereof, one can sculpt an aesthetically pleasing male buttock with a high degree of patient satisfaction.

Abstract
Gluteal augmentation has become a popular esthetic procedure since its inception. The main methods are augmentation using implants or autologous fat grafting, which is the harvesting and grafting of patients' own fat tissue. The last review comparing the safety of these methods was written 7 years ago, which warrants the writing of a new one. PubMed, Cochrane, and Medline were searched for studies focusing on the methods of gluteal augmentation listed previously. Five search terms were used and 15 studies fulfilled the criteria. The data were cataloged according to the method described and outcomes compared. Seven articles focused on gluteal implants and another seven assessed autologous fat grafting, whereas one detailed both. The most common complications in 524 implant procedures were wound dehiscence (9.16%), excessive implant palpability (5.92%), and seroma (3.82%), with an overall complication rate of 25%. The most common complications in 1788 gluteal fat augmentation procedures were seroma (6.9%), infection (3.0%), and transient sciatic paresthesia (1.0%), with an overall complication rate of 13%. Several articles listed satisfaction figures, but these were not assessed because this article was not powered to assess this outcome. Overall, gluteal augmentation using autologous fat grafting leads to fewer postoperative complications than implants and allows greater contouring of the buttocks and the surrounding areas. However, it can also be a far more dangerous procedure if certain recommendations are not followed.

Abstract
BACKGROUND Advances in gluteal fat grafting have resulted in diminished risks through improved understanding of regional anatomy and technical nuances. No anatomic studies identifying the presence or absence of buttock fat compartments have yet been reported. OBJECTIVES The aim of this cadaveric study was to identify and characterize the deep subcutaneous gluteal fat compartments to further understand the nuanced differences between deep and superficial subcutaneous fat layers. METHODS A cadaveric study was performed to identify the fat compartments. Latex injection into the iliac artery and vein was used to prepare 4 fresh (N = 8 hemibuttocks) hydrated cadavers for dissection. Preliminary work identified the likely position of deep gluteal fat compartments. The cannula was positioned under ultrasound guidance in between the superficial and deep gluteal layers. Cadaveric buttocks were infiltrated by the static technique with dyed human fat, dyed applesauce, and dyed saline in an attempt to identify the gluteal deep subcutaneous fat compartments. RESULTS Dissection identified and characterized 7 discrete deep gluteal fat compartments. These comprise 3 medial fat compartments (superior, middle, and inferior); a central fat compartment; and 3 lateral (superior, middle, and inferior) deep fat compartments. CONCLUSIONS Seven deep gluteal fat compartments have been identified that have distinct boundaries and maintain injected contents separate from each other above the gluteal muscle fascia. These compartments can be selectively expanded for buttock augmentation. Knowledge of these compartments enables surgeons to perform gluteal augmentation by static infiltration, injecting autologous fat under ultrasound guidance in the deep subcutaneous fat layer, while optimizing aesthetic considerations.

Abstract
BACKGROUND Autologous fat grafting has recently gained popularity in breast and reconstructive procedures. OBJECTIVES The aim of this paper was to describe a tricomposite tuberous breast reconstruction that comprises matrix dissociation through extensive tunnelization, tissue recruitment with loops, and autologous fat transfer. This approach, called "matrix modeling," was implemented by the power-assisted liposuction, loops, and lipofilling (PALLL) technique as a method to expand the lower pole, reshape the breast, and increase breast volume. METHODS Between 2014 and 2020, a total of 47 patients underwent tuberous breast correction by combined lipofilling and the use of breast loops. The patient population included patients with unilateral or bilateral tuberous breasts of any stage. Patients who were active smokers, lean, or who desired large breasts were excluded from the study. RESULTS Of the 47 patients (mean age, 26 years), 31 had bilateral malformations. The mean recruited flap volume was 212 mL. A single session (mean transfer volume, 163 mL) was required in 34 cases (72%). A second session (mean transfer volume, 182 mL) was necessary in the remaining 28% of cases. Patients were very satisfied in 93% of cases and satisfied in 7% of cases. One infection was observed. The mean operative time was 67 minutes. Imaging performed preoperatively and 1 year postoperatively did not reveal any anomalies other than oil cysts (4%). CONCLUSIONS Tricomposite breast reconstruction by PALLL is a novel, simple, safe, and alternative technique for tuberous breast correction by remodeling the matrix. The aesthetic outcome is natural, implant free, and long lasting. LEVEL OF EVIDENCE: 4

Abstract
BACKGROUND Autologous fat grafting has gained popularity in breast reconstructive surgery. To further increase the breast volume and provide a reliable breast shape, a skin flap can be advanced from the upper abdomen and lateral thorax to the breast. OBJECTIVES The aim of this study was to propose a method of breast reconstruction utilizing the principles of power-assisted liposuction and lipofilling (PALL) for breast matrix dissociation applied through infiltration, tunnelization, extensive undermining and lipofilling, in combination with loops (PALLL) to recruit a vascularized flap to reshape the breast. METHODS A prospective study was performed from January 2014 to January 2019. Demographic data, surgical procedure information (including volumes of the recruited advancement flap and lipofilling, and stages of lipofilling), and complication data were collected. Patient-reported outcomes, including satisfaction and well-being, were measured by a questionnaire. RESULTS In total, 37 women (41 breasts) underwent breast reconstruction by PALLL with an average follow-up of 26 months. The mean age of the patients was 54 years, and their mean BMI was 29 kg/m2. The mean recruited flap volume was 197 mL, and the mean lipofilling volumes were 153 mL for the first session, 190 mL for the second session, and 110 mL for the third session. Nine patients needed 3 sessions, 27 patients 2 sessions, and 1 patient only 1 session. Overall, 94% of patients were satisfied with their breast shape. All patients reported sensitive breasts. There were minimal complications. CONCLUSIONS Breast reconstruction with PALLL is a minimally invasive alternative to reconstructing and reshaping sensate breasts in which a vascularized skin flap recruited by loops from breast surroundings is combined with fat grafting. This approach provides long-term shape stability with minimal scarring and low complication rates. LEVEL OF EVIDENCE: 4

Abstract
BACKGROUND An increasing number of women wish breast implant removal whilst maintaining an acceptable projection and form were possible. OBJECTIVES The authors propose a technique to remodel the breast after implant removal utilizing internal suture loops to project the breast, recruit abdominal and axillary tissue cranially and medially, and provide a matrix for lipofilling. METHODS A prospective analysis was performed of consecutive patients undergoing implant extraction followed by power-assisted liposuction loops and lipofilling. Patient characteristics were measured. The aesthetic results were evaluated by 2 independent raters. Patient-reported satisfaction was measured by standardized questionnaires. RESULTS Implants in 52 patients with an average age of 55 and body mass index of 23.7 were extracted followed by breast remodeling. A total of 73% of patients had implants for aesthetic reasons, 41% were smokers, and 43% of the reconstruction cases received radiotherapy. A total of 28% had implant extraction for rupture, 58% for capsular contracture, and 14% due to pain and migration. The average volume of the implants removed was 292 cc, followed by an average lipofilling of 223 cc, yielding a ratio of 0.76 to 1. The average tissue recruited by loops was 82.5 cc. Independent raters measured 79% of results as good, 13% as acceptable, and 8% as requiring improvement; 80% of patients were satisfied to very satisfied. CONCLUSIONS The authors propose implant extraction followed by power-assisted liposuction loops and lipofilling can provide footprint definition, sustained projection, and high patient satisfaction. Moreover, the recruitment of a vascularized adipo-cutaneous flap by loops allows a reduced ratio of fat grafting to implant volume. LEVEL OF EVIDENCE: 4

Abstract
Autologous fat grafting in the setting of breast augmentation and reconstruction has become globally accepted and routinely performed. There is general consensus that small-volume grafting is reproducible and predictable; however, large-volume fat grafting (>100 mL) is less predictable and is not as commonly performed. The aim of this article was to review outcomes following large-volume and megavolume fat grafting in the setting of breast augmentation and reconstruction. Level of Evidence: 4.

Abstract
The number of gluteal augmentation procedures with implants has increased in the last years. However, due to high complication rates related to the placement of the implants, surgeons have started to avoid using implants. The objective of the present study was to describe the details of the submuscular gluteal augmentation technique together with lipoplasty techniques and to increase the prevalence of its use. METHODS All methods are complementary to each other rather than being superior to each other. That is why the author has used submuscular gluteal augmentation with implant technique and lipoplasty together during the surgeries. The complication rates are lower with this easy-to-learn technique described in this article. Eighty-six patients aged 20-46 underwent surgery. The follow-up period was 6-24 months. The implants used consisted of round cohesive silicone, with the most commonly used size being 330 cm3. The average volume of infiltrated fat was 514 cm3. RESULTS The sciatic nerve is well protected by the surrounding anatomical structures, indicating that submuscular technique can be used safely. Partial wound dehiscence was noted in 1 patient, implant malposition in 5 patients, and seroma in 2 patients. All patients reported that they are highly satisfied with the results of the procedure. CONCLUSIONS The author advocates that the combination of lipoplasty with the submuscular technique described is safe, easy to perform, has a short operative time and low complication rates. It can be preferred in buttock beautification as a simple and safe technique.

Abstract
BACKGROUND In continued interest to develop and refine minimally invasive procedures, recent publications reported a scarless approach in breast lifting. OBJECTIVES The authors sought to describe a power-assisted lipomodeling technique combined with surgical loops to achieve breast reduction and reshaping with minimal scars. METHODS Between 2014 and 2018, 94 patients underwent breast reduction by combined liposuction and loops. Following infiltration of the breasts, liposuction of the outer quadrants and the lower pole was achieved to reduce the breast footprint and the lateral and inferior heaviness of the breast. After multiaxial multiplanar tunnelization, 3 types of loops were taken around the breast to suspend and elevate the breast skin envelope and parenchyma. Each loop was guided through a 3-mm, 3-hole cannula passed through skin stab incisions. The first loop was designed to reduce the breast footprint and enhance the breast projection, whereas the second loop was designed to achieve breast conus remodeling. The third loop was passed circumferentially around the areola and then cephalad along the breast axis and pulled until the desired nipple-areola complex elevation was reached. Each loop was pulled to achieve the desired breast projection and shape. RESULTS The authors achieved breast reduction with a mean nipple elevation of 7.3 cm, and 88% of patients were satisfied with their breast shape. The total complication rate was 1%, including mild cellulitis in 1 breast, treated efficiently with oral antibiotics. CONCLUSIONS The proposed technique is a novel, simple, and safe alternative to achieve breast reduction and reshaping without a scar. LEVEL OF EVIDENCE: 4

Abstract
BACKGROUND Liposuction is the main technique to improve body contour, emphasize appealing curves, and highlight one's muscular definition. The number of procedures in which the harvested fat is utilized for gluteal augmentation has greatly increased. OBJECTIVES The authors aim to demonstrate their technique in order to obtain a sculpted harmonious body through a safe procedure, as well as review their 101 consecutive cases between 2014 and 2018. METHODS Anatomical guidelines and preoperative markings were provided to guide the 3-step procedure: zones of maximal and mild liposuction, barbed wire suspension, and moderate fat grafting. Novel concepts are introduced as the anterior body diagonal, posterior body diagonal as well as other specific axes the pubic unit, and a vertical ratio for the buttock, which are the basic foundations for sculpting the female body into a pleasing hourglass shape with a well projected buttock. Recommendations for location of sacral diamond, sacral dimples, and the maximally projected point of the buttock are given. The authors explain their philosophy through 4 principles: knowledge of anatomy, the relationship between specific body areas and surrounding zones, a balanced gluteal augmentation is not achieved through large volume fat grafting alone, and grafting in the subcutaneous layer. RESULTS A total of 101 patients were treated following the described technique and examples are shown. The complication rate was low. No serious adverse effects were recorded apart from 1 ruptured suspension loop. CONCLUSIONS The described anatomy-based approach, including liposuction, suspension loops, and fat grafting, is a novel and safe technique leading to a desirable, long-lasting outcome.

Abstract
BACKGROUND Fragments of subcutaneous adipose tissue that have been genetically modified to express bone morphogenetic protein-2 (BMP-2) regenerate large segmental osseous lesions in rodents. Gene-activated adipose tissue can be implanted into osseous defects without prior cell extraction and cell culture. The present study aimed to explore whether the heterodimers BMP-2/6 or BMP-2/7 exceed the osteoinductive effect of BMP-2 on adipose tissue. METHODS In an in vitro tissue culture system, freshly harvested rat subcutaneous adipose tissue was cultivated in the presence of either BMP-2 or BMP-2/6 or BMP-2/7 at a high (200 ng/ml) and low (50 ng/ml) concentration. Gene expression analysis as well as histological and immunohistochemical methods were applied to test for osteoinduction. RESULTS A concentration of 200 ng/ml of homodimeric BMP-2 induced osteogenic differentiation most potently, showing more calcification and a higher expression level of bone markers than both concentrations of BMP-2/6 or -2/7. A concentration of 50 ng/ml of BMP-2 was a significantly stronger osteogenic inducer than both concentrations of BMP-2/6 and the low concentration of BMP-2/7. The most potent heterodimeric driver of osteoinduction was BMP-2/7 at a high concentration, demonstrating effects similar to those of BMP-2 at a low concentration. CONCLUSIONS Homodimeric BMP-2 evoked osteoinduction within adipose tissue more potently and at a lower concentration than heterodimeric BMP-2/6 or BMP-2/7. This result agrees well with the fact that it might be easier to translate adipose grafts activated by homodimeric BMP-2 clinically. Preclinical in vivo gene transfer studies are necessary to confirm the results of the present study.

Abstract
BACKGROUND Power-assisted liposuction and lipofilling (PALL) is a simple and reproducible surgical technique for large volume fat grafting. OBJECTIVES The authors share their 7-year experience with their large-volume fat transfer technique, PALL. METHODS A total of 417 patients who underwent PALL-related surgeries involving the breast and buttock were evaluated in a retrospective study. Liposculpting and fat harvesting were performed with power-assisted liposuction. Fat was transferred with simultaneous power-assisted vibration and tunnelization to provoke expansion of the recipient site. Following lipofilling, additional external vibration of the recipient site was performed to enhance diffusion of the injected fat. RESULTS Liposuction volumes up to 5000 mL were recorded, and injection volumes ranged from 300 to 900 mL per side for each session. Operating times ranged from 45 to 120 minutes. Patients were followed-up for 1 to 4 years. No major complications were recorded. CONCLUSIONS PALL is an efficient, safe, and reproducible procedure with myriad applications in aesthetic and reconstructive surgery. Level of Evidence: 4.

Abstract
BACKGROUND Use of gluteal augmentation with fat increased by 3267% from 2002 to 2015, and the rate of death is highest compared with other aesthetic procedures: 1 in 3448 patients dies, compared with 1 in 55,000. OBJECTIVES To retrospectively investigate patients who underwent this procedure at Oslo Plastic Surgery Clinic, to review international data to determine factors causing mortality, and to provide guidelines for safety. METHODS Patient data were searched for reason for the procedure, assessment of patients, techniques performed, and safety measures used. In 60 cases, a vibration machine was used for fat harvesting. Review of the international literature, with special emphasis on fatal complications, was performed on Medline, Google Scholar, and PubMed. RESULTS Mean patient age was 32 years. Mean amount of grafted fat was 422 mL (range, 210-850 mL). Sedation, local and tumescent anesthesia were used in all patients, with mobilization directly after surgery. Mean operation time was 89 minutes. Eighteen patients required a second surgery. Minor complications occurred in 8 patients. Average follow-up was 8 months. Ninety percent of patients were satisfied. Review of international literature showed that the main reason for death in 2015 was fat lung embolism related to muscular and submuscular grafting. CONCLUSIONS Gluteal augmentation with fat is one of the most popular procedures, with an internationally high mortality rate. Patient safety is a priority, and preventive measures should improve safety because appropriate patient selection, avoiding muscular and submuscular grafting, avoiding infragluteal incision, moderate grafted volume, and direct postoperative mobilization are essential.

Gene activated adipose tissue fragments as advanced autologous biomaterials for bone regeneration: osteogenic differentiation within the tissue and implications for clinical translation. Sci Rep 2019; 9:224. [PMID: 30659209 PMCID: PMC6338750 DOI: 10.1038/s41598-018-36283-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Accepted: 10/26/2018] [Indexed: 02/06/2023] Open
Abstract
Cost-effective, expedited approaches for bone regeneration are urgently needed in an ageing population. Bone Morphogenetic Proteins (BMPs) stimulate osteogenesis but their efficacy is impeded by their short half-life. Delivery by genetically modified cells can overcome this problem. However, cell isolation and propagation represent significant obstacles for the translation into the clinic. Instead, complete gene activated fragments of adipose tissue hold great potential for bone repair. Here, using an in-vitro culture system, we investigated whether adenoviral transduction with human BMP-2 can promote osteogenic differentiation within adipose tissue fragments. Osteoinduction in adipose tissue fragments was evaluated by quantitative reverse transcriptase polymerase chain reaction, immunohistology and histomorphometry. BMP-2 transduced adipose tissue synthesized BMP-2 protein over 30 days peaking by day six, which significantly promoted osteogenic differentiation as indicated by increased calcium depositions, up-regulation of bone marker genes, and bone-related protein expression. Our results demonstrate that cells within adipose tissue fragments can differentiate osteogenically after BMP-2 transduction of cells on the surface of the adipose tissue. BMP-2 gene activated adipose tissue represents an advanced osteo-regenerative biomaterial that can actively contribute to osteogenesis and potentially enable the development of a novel, cost-effective, one-step surgical approach to bone repair without the need for cell isolation.

Abstract
BACKGROUND The number of gluteal fat augmentation procedures has increased recently and so has the number of complications. Because of the increased risk of morbidity and mortality when fat is injected intramuscularly, not knowing where fat is injected is concerning. We sought to identify the planes in which fat is injected during the procedure. METHODS We selected 15 consecutive female patients who desired gluteal fat augmentation. All patients had epidural anesthesia and the gluteal region was infiltrated with a vasoconstrictive solution. With the patient in prone position, an ultrasound probe placed on the buttocks was used to identify the fascial layers. While decanted fat was being injected with a blunt cannula, the images were projected wirelessly to a screen, so that the surgeon and assistant could follow the planes in which the cannula was being introduced and the fat injected. RESULTS The mean volume of harvested fat was 3533 ml and the mean volume of fat injected per gluteal region was 528 ml. The evaluation of the depth and location of the cannula was performed in real time with the ultrasound, accurately and reliably identifying the planes of fat injection. All injections were subcutaneous. The downsides of this technique were the purchase cost of the ultrasound device, increased surgical time, the need for an assistant to follow the cannula and the probe constantly, and the learning curve. CONCLUSION Real-time ultrasound-assisted gluteal fat grafting is reliable and may avoid injuring the deep vessels, further decreasing the risks of major complications.

Abstract
BACKGROUND Despite rapid growth, gluteal fat transplantation is an operation in search of science and a teachable technique. Long operating times, tedious syringe transfers, inability to shape the recipient site, and the risk of fat embolism all headline as impediments to clinical adoption of the procedure. Expansion vibration lipofilling is a syringe-free surgical strategy that is a logical extension of Separation, Aspiration, and Fat Equalization (SAFELipo). In expansion vibration lipofilling, there is simultaneous disruption of recipient-site connective tissue, internal expansion using exploded-tip cannulas, and backfilling of these spaces with roller pump-propelled fat. METHODS Two thousand four hundred nineteen consecutive cases of expansion vibration lipofilling fat transplantation to the buttocks were reviewed. Average follow-up was 12 months. The technique of expansion vibration lipofilling is dependent on the use of larger caliber cannulas attached to a roller pump and to an oscillatory power-assisted liposuction device, which is less labor-intensive, potentially allowing for better knowledge of cannula-tip location at all times during the procedure. RESULTS Operating times averaged 1 hour 40 minutes. The average volume of fat inserted was 1003 cc. Complications included donor-site seroma, infection, and one pulmonary embolism treated with anticoagulation. There were no cases of fat embolism or death. CONCLUSIONS Expansion vibration lipofilling is a new method for large-volume fat transplantation. Avoidance of fatal fat emboli demands a surgeon's complete knowledge of cannula tip location at all times during the procedure. Syringe-free, larger caliber, and less flexible cannulas, combined with techniques requiring less operator upper extremity effort resulting in less fatigue, may contribute to avoidance of this dreadful complication.

Abstract
BACKGROUND The number of buttock augmentations with fat transfer is steadily increasing, but a number of fatalities caused as a direct result of gluteal fat grafting have been reported. The technical details relating to cannula size, injection angle or trajectory, and plane of injection are critical for avoiding morbidity and mortality. However, the ligamentous anatomy has not been thoroughly explored, particularly how the ligaments are encountered in the clinical setting of fat transfer by means of cannulas. METHODS The gluteal regions of five fresh cadavers were dissected, for a total of 10 hemidissections. All pertinent cutaneous ligaments in the region were identified. In addition, cannulas were used to simulate typical variations in injection planes. RESULTS The osseocutaneous and fasciocutaneous ligaments of the buttocks were identified. CONCLUSIONS The authors describe important ligamentous structures consistently found in the region in cadaveric dissections and discuss the implications while safely performing gluteal augmentation. The anatomical features, boundaries, and soft-tissue attachment points may play a role in cannula-directed fat injection misguidance. The ligaments, when not released, can lead to undesired deep injection and therefore fat lobule migration into the venous system. The density, danger zones, and soft-tissue attachments must be clarified further as we continue to offer our patients improved buttock contour with a higher safety profile.

Abstract
BACKGROUND Autologous buttock augmentation with fat grafting has emerged as one of the preeminent modalities for body contouring employed by plastic surgeons today. Since 2009, we have used the roller pump injection technique. OBJECTIVES This procedure can be performed safely without specialized equipment and eliminates the tasks of manual graft preparation and injection. We describe our technique and standard safety measures. The anatomy of and complications associated with liposuction and fat grafting were recorded and reviewed. METHODS Retrospective chart review of 916 patients who underwent autologous buttock augmentation by this method from February 2009 to November 2016 was performed. All procedures were performed under general anesthesia at the same surgical center. Liposuction was performed and using a roller pump, the fat layer was propelled through an open-ended cannula into the recipient site. RESULTS Mean volume of fat removed and fat grafted in each patient was 3156 mL and 1807 mL per patient, respectively. There were complications in 13 patients for a rate of 1.4% with 10 (1.1%) related to fat grafting. Fourteen patients (1.5%) had subsequent procedures for volume and four patients (0.44%) for asymmetry. There were no venous thrombolic events, fat embolic events, or deaths. CONCLUSIONS The roller pump injection technique for buttock augmentation with fat grafting is safe and efficient. This technique minimizes preparatory effort and does not require additional equipment. We were unable to identify variables associated with complication risk due to the power of this study and the low percentage of complications. LEVEL OF EVIDENCE 4

Abstract
Gluteal augmentation with fat transplantation is increasing in demand but has been associated with a concerning number of fatality reports. Despite these reports, various surgeons have safely performed gluteal fat transplantation on a large number of patients with no reported mortality. The important aspects of safely performing gluteal fat transplantation are reviewed. Proper patient selection, favorable instrumentation, patient positioning, proper technique, and knowledge of anatomy are critical to improving the safety of this procedure. Adherence to these key principles should allow a reduction in mortality from this procedure, which would safely allow its continued offering in the setting of increasingly high demand.

Abstract
BACKGROUND With the increasing demand for gluteal fat augmentation, reports of fatal complications have surfaced. Therefore, the authors proposed to analyze the published techniques and compare different protocols, to identify those of potential concern. METHODS A systematic review of the literature was performed with a search of 21 terms on the PubMed, MEDLINE, Cochrane, and Scientific Electronic Library Online databases. Nineteen articles meeting our predetermined criteria were analyzed, and data from the different steps of the procedure were classified, allowing evaluation and comparison of techniques. Independent-samples t test and one-way analysis of variance were used for statistical analysis. RESULTS Seventeen case series and two retrospective studies including 4105 patients were reviewed. Most articles were authored in Colombia, Mexico, and Brazil. Most procedures were performed on adult female patients under general anesthesia. Fat was harvested using a tumescent technique from the lower extremities and the back, with machine-vacuum suction. A mean of 400 ml of decanted lipoaspirate was injected into each gluteal region, mostly subcutaneously and intramuscularly with 60-ml syringes. Most patients rated their results as "excellent." The mean complication rate was 7 percent (6.7 percent minor, 0.32 percent major), with no significant relation to the planes of injection. CONCLUSIONS Fat grafting is an effective and predictable way to remodel the gluteal region; however, the procedure is not without risks. Avoiding gluteal vessel damage may prevent most feared complications, such as fat embolism. Accurate analysis, systematization of the procedure, and reporting cases in the fat grafting registry may provide the foundation for optimization of outcomes.

Abstract
BACKGROUND Current brachioplasty techniques include excisional surgery alone or in combination with liposuction. These techniques are associated with poor outcomes, such as residual contour deformities and unfavorable scarring. OBJECTIVES The authors proposed a new classification system and treatment algorithm for brachial ptosis and described their experience with power-assisted liposuction and lipofilling to treat brachial ptosis without excisional surgery. METHODS Ninety-five patients with grades 1, 2, or 3 brachial ptosis who underwent brachioplasty were evaluated in a prospective study. Power-assisted liposuction was applied to the posterior arm and para-axillary region, and power-assisted lipofilling was applied to the so-called "bicipital triangle" of the medial arm. RESULTS The patients' mean age was 39 years, mean body mass index was 28 kg/m(2), mean lipoaspirate volume was 240 mL per arm, and mean fat-injection volume was 110 mL per side. The mean operating time was 50 minutes, and the average follow-up period was 24 months. Hematoma developed in 2 patients who underwent brachioplasty in combination with another body contouring procedure (1 abdominal hematoma and 1 thigh hematoma; 2.1% complication rate). No other complications were recorded. CONCLUSIONS Brachioplasty by means of power-assisted liposuction and lipofilling is a safe and reliable option that obviates excisional surgery in patients with mild to moderate brachial ptosis.

Abstract
Supplemental Digital Content is available in the text. Background: Buttock fat transfer is now the preferred method for gluteal augmentation. However, its efficacy has not been well-documented using measurements. Methods: Twenty-five consecutive patients underwent buttock fat transfer performed by the author. Twenty-one patients returned for measurements ≥3 months after surgery (inclusion rate, 84%). A separate group of 25 patients undergoing cosmetic surgery without buttock fat transfer served as controls. All patients underwent superwet liposuction using total intravenous anesthesia and no prone positioning. A closed filtration system was used to collect the fat. Subcutaneous fat thickness was assessed using ultrasound imaging. Measurements were made on standardized photographs. The data were controlled for change in body mass index. Clinical data were also evaluated. Results: The mean fat volume injected per buttock was 287 mL (range, 70–550 mL). Ultrasound measurements detected a significant increase in the subcutaneous fat thickness (P ≤ 0.001), with mean increments of 0.66 cm for the right buttock and 0.86 cm for the left buttock and no significant change for control patients. The mean calculated fat retention, based on the measured surface area injected, was 66%. Photographic measurements of buttock projection revealed a significant increase in treated patients (P < 0.01) and no significant change in control patients. There were no clinical complications at either recipient or donor sites and no evidence of oily cysts on ultrasound examinations. Conclusions: Photographic and ultrasound measurements, and clinical findings, confirm that buttock fat transfer effectively and safely increases buttock projection.
