Safety Comparison of Abdominoplasty and Brazilian Butt Lift: What the Literature Tells Us

Scarpa fascia preservation abdominoplasty combined with precise liposuction for postpregnancy abdomen: A 10-year experience

BACKGROUND

Abdominoplasty is widely performed in plastic surgery. Currently, there is a high demand for abdominoplasty among women who experience abdominal wall laxity after pregnancy. The aim of this study was to present modified abdominoplasty combined with power-assisted liposuction and ultrasound-assisted liposuction for postpregnancy women with abdominal wall laxity.

METHODS

This retrospective study included a total of 190 cases of postpartum women presenting with abdominal wall laxity from January 2015 to April 2023. The patients were divided into 2 groups: the abdominoplasty and abdominoplasty combined with precise liposuction groups. The age, body mass index, reproductive history, abdominal circumference, surgical strategy, surgical details, and complications were considered during evaluation. Patient satisfaction was evaluated using a questionnaire that incorporated the visual analog scale (VAS) and Beck Depression Inventory (BDI).

RESULTS

The average postoperative follow-up period in this study group was 10.1 months. The abdominoplasty combined with precise liposuction group exhibited significantly reduced upper and lower abdominal circumferences compared to the abdominoplasty group (P<0.05). The postoperative VAS score of the combined group was significantly higher than that of the abdominoplasty group (P<0.05), while the postoperative BDI score of the combined group was significantly lower compared to that of the abdominoplasty group (P<0.05). The BDI results revealed a significant reduction in the prevalence of moderate depression among post-surgery patients, declining from 94.2% to 3.6%.

CONCLUSIONS

Scarpa fascia preservation abdominoplasty combined with precise liposuction is a suitable procedure for postpregnancy abdomen. The modified abdominoplasty demonstrates favorable therapeutic outcomes, optimal flap blood supply, minimal flap tension, inconspicuous postoperative scar, and meticulous body contouring.

Multidisciplinary Experience for Gluteal Fat Grafting

BACKGROUND

Gluteal fat grafting, colloquially known as Brazilian Butt Lift, has experienced a significant rise in popularity in recent years. Despite this increase, potential complications associated with the procedure have also been observed, necessitating a thorough examination of the current practices and outcomes.

METHODS

This study collected experiences of a multidisciplinary group of surgeons through a detailed survey sent in April 2022. This study aimed to shed light on the practices employed by these surgeons, the frequency and types of complications they encounter, and the overall outcomes of their procedures.

RESULTS

Of the 100 surgeons surveyed, 86 responded. The study identified that pulmonary fat embolism (PFE) was the most serious complication, with fatality due to PFE recorded at a rate of 1:23,878. Liposuction site seromas were the most common complications, with an overall rate of 2.45%. Although there were no overall differences in complications between plastic and non-plastic surgeons, plastic surgeons were found to have a sixfold increase in the odds of experiencing a liposuction seroma. The survey also revealed substantial practice variations, particularly regarding fat preparation methods, recipient-site preparation, antibiotic use, and postoperative care protocols.

CONCLUSION

Despite known complications, a strong tendency to continue performing these procedures was observed among surgeons, demonstrating the sustained demand and acceptance of the procedure. This study underscores the need for continued surveillance and research to enhance the safety and effectiveness of gluteal fat grafts. The experiences and data gathered from practicing surgeons provide valuable insights, paving the way for refining techniques, building consensus, and facilitating informed discussions with patients about the risks and benefits of the procedure.

A Bibliometric Analysis of the Top 100 Papers on Gluteal Augmentation

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.

Brazilian Butt Lift: An Experience Over 3000 Patients

INTRODUCTION

The Brazilian Butt Lift (BBL) is a safe technique that entails body reshaping through buttock augmentation using autologous fat transfer.

METHOD

Between 2018 and 2022, 3000 patients underwent surgery. Each procedure commenced with the patient in supine position, starting with abdominal liposuction, followed by fat transfer to hips. Subsequently, the patient was repositioned to a prone stance. Liposuction of the back and waist ensued, concluding the surgery with fat transfer to the buttocks. Stringent precautions were implemented to ensure the safety of the patient throughout the procedure.

RESULTS

Eighty-six percent of patients express satisfaction with their outcomes, while seventy percent of the transferred fat calls survive in the buttocks. One serious complication and some minor complications have been encountered and effectively managed through conservative measures.

CONCLUSION

BBL proves to be a safe and satisfactory surgery when performed by experienced surgeons who adhere to fundamental principles.

Superficial Intramuscular Gluteal Lipograft by Doppler Ultrasound: A Report of 24 Patients

Background

Gluteal fat grafting is a common procedure in liposculpture. This study proposes a Doppler ultrasound-guided intramuscular and subcutaneous gluteal lipotransfer technique that allows for visualization of the location of the gluteal vessels, avoiding approaching them during lipotransfer by having the cannula localized during fat infiltration.

Methods

This new technique was applied to 24 women after obtaining informed consent and providing them with a clear explanation of potential risks and complications. Doppler ultrasound was used to locate the site and depth of blood vessels, and for quadrant scanning of vessels and superficial intramuscular visualization of the cannula's location. Intramuscular lipotransfer was performed with a volume of 400 mL per gluteus (or less), and 12 patients underwent magnetic resonance imaging before and 3 months after surgery.

Results

This technique allowed for visualizing the location of the gluteal vessels, and infiltration could be easily performed in patients. In the 24 glutei reviewed postsurgery, from 12 patients who underwent pre- and postsurgery magnetic resonance imaging, intramuscular fat was found; however, there was no migration outside the gluteus maximus muscle.

Conclusions

No local or systemic complications were observed. The results of our report show that fat filtration did not migrate outside the gluteus maximus muscle. This finding seeks to promote new research to create theoretical/practical precedents for the intervention of plastic surgeons and, from there, promote the standardization of a new and safe technique.

Combining Gluteal Shaping with High-Definition Liposuction: New Concepts and Techniques

Gluteal contouring has been subject to numerous publications in aesthetic plastic surgery. Not only the female but also the male features that govern such procedures have been thoroughly described by different authors. In this article, we will provide the reader with an updated account of how gluteal contouring blends with High Definition Liposculpture (HDL). We discuss the most current techniques for buttocks reshaping through a holistic approach of new anatomical and artistic concepts. We will dive into new techniques to perform multiplanar and 4-dimensional Fat Grafting and equalization of the buttocks and surrounding areas, which we believe might help plastic surgeons to improve the quality of their patient outcomes. In effect, a proper understanding of the anatomical structures and its variations among different gender and ethnicities, will both help the surgeon to individualize the procedure based on patient preferences.

Ant Waist Surgery: Aesthetic Removal of Floating Ribs to Decrease the Waist-hip Ratio

Decreasing waist circumference has become an essential feature in modern body contouring surgery owing to the attractiveness of hourglass body shapes. Traditionally, this can be achieved through lipomodeling and abdominal musculature strengthening techniques. An adjunctive procedure for ideal shaping of the waistline is resection of the 11th and 12th ribs, referred to as floating ribs. This study aimed to report and analyze clinical outcomes and self-reported patient satisfaction after "ant waist" surgery (floating rib removal) for aesthetic reasons. We retrospectively reviewed the medical records of five patients who had undergone bilateral 11th and 12th rib resections at a single institute in Taiwan in an outpatient setting. The mean lengths of the resected left and right 11th ribs were 9.1 and 9.5 cm, respectively. The mean lengths of the resected left and right 12th ribs were 6.3 and 6.4 cm, respectively. The mean waist-to-hip ratio decreased from 0.78 preoperatively to 0.72 postoperatively, with a mean decrease of 7.7%. No adverse events were reported. Generally, all patients reported being satisfied with the operation. Floating rib resection proved useful and effective in decreasing the waist-to-hip ratio using a safe, simple, and reproducible technique without significant complications. Although preliminarily, the authors' comprehensive demonstration of this ant waist surgery supports further studies focusing on waistline contouring.

Brazilian Butt Lift-Associated Mortality: The South Florida Experience

BACKGROUND

Brazilian butt lift (BBL) surgery has been the fastest growing aesthetic surgical procedure over the past decade. By 2017, the risk of death from pulmonary fat (PFE) was identified, earning the BBL the highest mortality rate of any aesthetic surgical procedure. South Florida carries the highest BBL mortality by far in the nation.

OBJECTIVES

The purpose of this study was to explore the factors involved in making South Florida an outlier in terms of BBL mortality.

METHODS

The anatomic findings of the gluteal dissections from 11 post-BBL surgery autopsies (22 hemibuttocks) were assessed for commonalities. The public records of patients who died from BBL-related fat emboli were examined to determine commonalities.

RESULTS

All BBL PFE cases had fat grafts injected into the gluteal musculature in multiple different levels. Another commonality involved the location where the surgery took place, with the great majority of patients (92%) undergoing surgery at high-volume, budget clinics located in South Florida. Short surgical times of approximately 90 minutes appeared to be the norm for these cases.

CONCLUSIONS

South Florida has experienced 25 BBL-related fat emboli deaths between 2010 and 2022; however, 14 of these occurred after publication of the Aesthetic Surgery Education and Research Foundation's 2018 guidelines and the 2019 Florida Board of Medicine's BBL "subcutaneous-only" rule. The working environment at the clinics, and the short surgical times for these cases, may be the most important contributors to the BBL mortality in South Florida.

The British Association of Aesthetic Plastic Surgeons (BAAPS) Gluteal Fat Grafting Safety Review -and Recommendations

Superficial gluteal lipofilling (SGL) is a fat grafting procedure that is performed to correct a trochanteric depression and buttock deflation. Brazilian Butt Lift (BBL) is gluteal lipofilling procedure traditionally associated with exaggerated appearance and intramuscular fat transfer. The risk of mortality from fat embolism in Brazilian Butt Lift (BBL) was previously reported as being 1:2500. The actual risk was later estimated to be nearer 1:15,000, which is similar to the mortality risk in abdominoplasty. There is increasing evidence regarding the safety of subcutaneous gluteal lipofilling. This has principally been related to new technologies, surgical techniques and training being developed to avoid intramuscular injection of fat. The efficacy and benefits of using intraoperative ultrasound scan has been demonstrated in guiding the subcutaneous placement of fat and avoiding inadvertent deep lipofilling. Other serious risks and complications must be considered in addition to mortality. These include hypothermia, sepsis, skin necrosis, and poor aesthetic results, as well as the much-publicised risk of fat embolism. Complications are better controlled and managed in strictly regulated healthcare settings. Patients seeking surgery at unregulated facilities or via medical tourism are deemed to be at higher risk of being exposed to these serious complications and/or inadequate subsequent management.
