Optimizing Brazilian Buttock Lift Results Using the BBL Assessment Tool.

The most distinguished feature of the female silhouette is the buttock. As such, the Brazilian Butt Lift (BBL) has become the most popular plastic surgery procedures in recent years. Despite the popularity of this buttock reshaping and augmentation procedure, there remains no prevailing standard for evaluating, planning surgical design, and objectifying buttock size and shape outcomes. In fact, we have observed a wide range of preferred buttock size and shapes among our patients. We have previously published the BBL assessment tool that serves to guide patient communication of their preferred buttock size and shape. In this study, we demonstrate how the BBL assessment tool can serve to optimize Brazilian Buttock Lift results. We present 25 case studies of how the BBL assessment tool can serve to optimize BBL results by providing a guide for evaluation, surgical design, and objectification of outcomes.Level of Evidence IV Therapeutic study.

MRI assessment of minimally invasive anterolateral approaches in total hip arthroplasty.

INTRODUCTION: Total hip arthroplasty (THA) on a minimally invasive anterolateral (MIAL) approach frequently leads to gluteus minimus and gluteus medius lesions, and sometimes to tensor fasciae latae (TFL) denervation. We therefore developed compensatory strategies, which we assessed on pre- and post-operative MRI: 1) to assess gluteus minimus and gluteus medius fatty infiltration (FI), 2) to assess TFL FI, and 3) to assess FI in the other periarticular muscles. HYPOTHESIS: The modified MIAL approach reduces the rate of gluteus minimus and gluteus medius lesion. MATERIALS AND METHODS: A continuous prospective single-surgeon series of THA using a MIAL approach included 25 patients. Femoral implantation was performed with the hip in extension so as to distance the proximal femur from the gluteals, avoiding muscle trauma. The superior gluteal nerve branch in the space between the gluteus medius and TFL, running toward the TFL, was systematically released and protected. MRI was performed preoperatively and at 3 months and 1 year post-surgery. FI was analyzed according to the Goutallier classification in all periarticular muscles. RESULTS: One patient lacked preoperative MRI and was excluded, leaving 24 patients, for 72 MRIs. In 10/24 patients (41.7%) the gluteus minimus and in 8/24 patients (33.3%) the anterior third of the gluteus medius showed ≥2 grade increase in FI between preoperative and 1-year MRI, with significant increases in both at 3 months (p<0.001) and 1 year (p<0.001). At least a 2 grade increase in FI at 1 year was seen in 1 patient (4.2%) in the TFL, in 2 (8.3%) in the piriformis, and in 1 (4.2%) in the obturator internus. There were no significant differences in FI between preoperative, 3-month or 1-year MRI in any other periarticular muscles. CONCLUSION: Femoral implantation in hip extension did not reduce the rate of gluteal lesions, which remained frequent. In contrast, release of the superior gluteal nerve branch could be effective in conserving TFL innervation. Some rare lesions of the proximal part of the pelvi-trochanteric muscles were also observed. LEVEL OF EVIDENCE: IV, Prospective case series.

Comparative MRI assessment of three minimally invasive approaches in total hip arthroplasty.

INTRODUCTION: Minimally invasive approaches (direct anterior approach: DAA; minimally invasive anterolateral: MIAL; piriformis-sparing posterior approach: PSPA) are widely used for total hip arthroplasty (THA), with a muscle-sparing objective. There are no published comparative studies of muscle damage secondary to these approaches. The aim of the present study was to compare fatty infiltration (FI) on MRI induced by DAA, MIAL and PSPA in THA 1) in the tensor fasciae latae (TFL) and sartorius muscles, 2) in the gluteal muscles, and 3) in the pelvitrochanteric muscles. HYPOTHESIS: Greater FI is induced by DAA in anterior muscles, by MIAL in gluteal muscles and by PSPA in pelvitrochanteric muscles. MATERIALS AND METHODS: Three continuous prospective series of THA by DAA, MIAL and PSPA included 25 patients each. MRI was performed preoperatively and at 1 year postoperatively. FI was graded on the Goutallier classification in all periarticular hip muscles. Muscles showing ≥2 grade aggravation at 1 year were considered damaged. RESULTS: Nine patients whose preoperative MRI was uninterpretable were excluded. In all, 66 patients (21 DAA, 24 MIAL and 21 PSPA) with 132 MRI scans were analyzed. TFL was damaged in 2/21 DAA patients (9.5%), 1/24 MIAL patients (4.2%) and 0/21 PSPA patients (0%). There were no sartorius lesions. The anterior third of the gluteus medius was damaged in 8/24 MIAL patients (33.3%) and the gluteus minimus in 10/24 (41.7%), compared to 1/21 DAA patients (4.8%) and 0/21 PSPA patients (0%). The mid and posterior thirds of the gluteus medius and the gluteus maximus were never damaged. The piriformis muscle was damaged in 3/21 DAA patients (14.3%), 2/24 MIAL patients (8.3%) and 2/21 PSPA patients (9.5%). The obturator internus was damaged in 4/21 DAA patients (19%), 1/24 MIAL patients (4.2%) and 16/21 PSPA patients (76.2%). The obturator externus and quadratus femoris were mainly damaged in PSPA patients: respectively, 5/21 (23.8%) and 4/21 patients (19%)). CONCLUSION: The muscle-sparing properties of minimally invasive hip approaches are only theoretical. In the present series, there were rare TFL lesions with DAA and MIAL. Gluteus medius and minimus lesions were frequent in MIAL. Pelvitrochanteric muscles lesions were more frequent in PSPA, but found in all 3 approaches. These findings should help guide surgeons in their choice of approach and in informing patients about the damage these minimally invasive approaches can cause.

Objectifying High-Definition Brazilian Buttock Lift Results Using the Buttock Assessment Tool.

BACKGROUND: The buttock is an essential feature of the female silhouette. This has led to the rise of the Brazilian butt lift as one of the most popular plastic surgery procedures in recent years. Despite this popularity, there remains no prevailing standard for the ideal buttock size and shape. In fact, a wide range of preferred sizes and shapes among the authors' patients has been observed. The authors hypothesized that age, religious affinity, and ethnic differences may demonstrate different buttock size and shape preferences. METHODS: The authors designed the buttock assessment tool, which utilizes digitally altered buttock sizes and shapes to determine desired buttock shape (upper, middle, and lower pole maximum fullness) and buttock size (waist-to-hip width ratio) for both the posteroanterior and lateral views. A survey of 422 patients was completed, evaluating variation of desired buttock size and shape based on patient age, cultural, and ethnic differences. RESULTS: There were significant differences in buttock size and buttock shape based on age, ethnicity, and religion. Hispanics and African Americans were twice as likely as Caucasians to request lower pole fullness in the posteroanterior view. Older respondents preferred a smaller buttock in both views. African Americans preferred a larger buttock compared to Caucasians in both views. Hispanics preferred a larger buttock in only the lateral view. Muslim respondents preferred a smaller buttock in the posteroanterior view. CONCLUSION: The Brazilian buttock assessment tool has become critical to understanding and delivering prospective Brazilian butt lift patients' goals by objectifying buttock size and shapes.

Responsiveness of the Victorian Institute for Sport Assessment for Gluteal Tendinopathy (VISA-G), modified Harris hip and Oxford hip scores in patients undergoing hip abductor tendon repair.

BACKGROUND: A lack of consensus exists on which patient-reported outcome measures (PROMs) best evaluate change following hip abductor tendon (HAT) repair. OBJECTIVES: To compare the responsiveness of the Victorian Institute for Sport Assessment for Gluteal Tendinopathy (VISA-G), Oxford Hip (OHS) and modified Harris Hip (mHHS) scores in patients undergoing HAT repair. STUDY DESIGN: Prospective case series. METHODS: 56 patients underwent HAT repair and were evaluated pre-surgery and 3, 6 and 12 months post-operatively using the VISA-G, OHS, mHHS and a Global Rating of Change (GRC) scale. Internal and external responsiveness, the minimal clinically important change (MIC) and the presence of ceiling effects were evaluated. The extent to which VISA-G change was associated with mHHS and OHS change was investigated, as was the extent to which PROM changes were discriminatory for GRC improvement. RESULTS: All PROMs demonstrated large standardized effect sizes (>1), with the VISA-G demonstrating responsiveness similar to the mHHS and OHS. At 12 months, the GRC correlated similarly with VISA-G (0.42, 95% CI: 0.17-0.61), mHHS (0.44, 95% CI: 0.17-0.61) and OHS (0.53, 95% CI: 0.31-0.70) changes. Using a GRC anchor of ≥4, an MIC of 29/100, 29/91 (32/100) and 16/48 (33/100) was observed for the VISA-G, mHHS and OHS, respectively. At 12 months ceiling effects existed for the mHHS (18/56, 32.1%) and OHS (13/56, 23.2%), but not VISA-G (1/56, 1.8%). CONCLUSION: The VISA-G demonstrated acceptable responsiveness and was more resistant to ceiling effects, though demonstrated similar change scores and correlations with perceived improvement to the mHHS and OHS.

The Ideal Thigh: A Crowdsourcing-Based Assessment of Ideal Thigh Aesthetic and Implications for Gluteal Fat Grafting.

BACKGROUND: As the popularity of aesthetic gluteoplasty continues to grow, there is renewed focus on defining the ideal buttocks. However, the literature lacks studies characterizing an ideal thigh, despite the impact of thigh contour on overall gluteal aesthetic. OBJECTIVES: The authors performed the first population analysis of the characteristics of perception of attractive thighs, to identify a role for fat grafting of the thigh in gluteoplasty. METHODS: Survey images were digitally modified to create thighs of varying widths and angles relative to fixed buttocks. Thigh-to-buttock ratios and the buttock-thigh junction were studied. Data were stratified and analyzed according to age, gender, and ethnicity of the respondents. Amazon Mechanical Turk was used as a novel crowdsourcing platform for surveying aesthetic preferences. RESULTS: A total of 1034 responses were included of whom 54.4% were male, and 45.6% were female. All age groups and ethnicities were represented. Overall, 43.8% of respondents preferred the widest buttock-thick junction angle on posterior view. There was no clear preference between larger or smaller thigh-to-hip ratios on lateral view. CONCLUSIONS: Characteristics of the ideal thigh include wider thighs with greater horizontal projection, creating a more natural contour from the augmented buttock. These findings represent a paradigm shift from the traditionally assumed preference for slender thighs. Plastic surgeons should carefully consider thigh anatomy in their gluteal augmentation patients, as simultaneous thigh augmentation may lead to a more aesthetically pleasing outcome. Further research is needed into best practices and techniques to attain ideal thigh proportions.

Population Health Implications of Medical Tourism.

BACKGROUND: Fifteen million U.S. patients each year seek medical care abroad; however, there are no data on outcomes and follow-up of these procedures. This study aims to identify, evaluate, and survey patients presenting with complications from aesthetic procedures abroad and estimate their cost to the U.S. health care system. METHODS: A single-center retrospective review was conducted. A cohort of patients presenting with complications from aesthetic procedures performed abroad was generated. Demographic, complication, and cost data were compiled. Patients were surveyed to assess their overall experience. RESULTS: Over a 36-month period, 42 patients met inclusion criteria (one man and 41 women), with an average age of 35 ± 11.4 years (range, 20 to 60 years). Comorbidities included four active smokers, two patients with hypertension, and one patient with diabetes. Average body mass index was 29 ± 4.4 kg/m (range, 22 to 38 kg/m). Procedures performed abroad included abdominoplasty (n = 28), liposuction (n = 20), buttock augmentation (n = 10), and breast augmentation (n = 7), with several patients undergoing combined procedures. Eleven patients presented with abscesses and eight presented with wound dehiscence. Eight of the 18 patients who were surveyed were not pleased with their results and 11 would not go abroad again for subsequent procedures. Average cost of treating the complications was $18,211, with an estimated cost to the U.S. health care system of $1.33 billion. The main payer group was Medicaid. CONCLUSIONS: Complications from patients seeking aesthetic procedures abroad will continues to increase. Patients should be encouraged to undergo cosmetic surgery in the United States to improve patient outcomes and satisfaction and because it is economically advantageous.

A Prospective Assessment of Surgical Risk Factors in 114 Gluteal Fold Flap Reconstructions After Oncological Vulvoperineal Resection.

BACKGROUND AND AIM: To date, clinically relevant selection criteria have not been established for the use of the gluteal fold flap after oncological vulvoperineal resection. We prospectively assessed the surgical risk factors of this reconstructive technique in a large series. METHODOLOGY: From April of 2000 through December of 2015, 114 gluteal fold flaps were used for vulvoperineal reconstruction after excision of (pre)malignant skin disorders in 75 women. The possible influence of 10 patient-related and 6 procedure-related risk factors on flap-related postoperative complications was statistically analyzed. RESULTS: We observed a major complication in 13 flaps (11%) and a minor complication in 19 flaps (17%). Previous radiotherapy (P = 0.01) was associated with significantly more complications, and a rotation flap design rather than VY advancement (P = 0.02) was associated with major complications. Recurrent disease, multifocal tumor localization, incomplete removal of tumor, and bilateral flap procedure were found to be clinically relevant risk factors, but not significantly so. The same applied to recurrence of disease during postoperative follow-up. CONCLUSIONS: We identified surgical risk factors for gluteal fold flap use after oncological vulvoperineal resection. These observations may potentially allow for more favorable future surgical outcomes by adaption of selection of patients or procedure.

Reimbursement for tissue reconstruction by pedicled and free flaps across five European countries. The importance of autologous breast reconstruction.

AIM: Case payment mechanisms have become the principle means of remunerating hospitals in many countries. We analysed the reimbursement for different types of autologous tissue transfer in five European countries. METHODS: We looked at common surgical options for breast reconstruction and flaps at other body regions. The principle diagnosis was systematically modified and processed with national grouper software to identify the relevant Diagnosis-Related Groups. RESULTS: The mean difference in payment was 4509 € in breast reconstruction versus only 2599 € in other locations. According to the underlying diagnosis for reconstruction, procedures after resection of malignant breast cancer showed higher reimbursement (mean 8319 €) than of other body parts (mean 6454 €). Sweden had the highest mean reimbursement (9589 €) followed by Austria (8032 €), Germany (7259 €), Italy (6667 €) and the UK (6037 €). Austria, Italy and the UK showed significant differences of reimbursement between pedicled flaps of the breast and other parts of the body. CONCLUSION: International data for the benchmarking and refinement of a national compensation system can be a useful instrument in identifying ways of improving each system. Across a spectrum of European countries, reimbursement for the reconstruction of the breast and other body parts was analysed and characteristics were identified. As rationalisation of healthcare becomes widespread in European countries, the need for individualised reimbursement which correlates accordingly is becoming ever more important.

Preoperative color Doppler assessment in planning of gluteal perforator flaps.

Gluteal artery perforator flaps have gained popularity due to reliability, preservation of the muscle, versatility in flap design without restricting other flap options, and low donor-site morbidity in ambulatory patients and possibility of enabling future reconstruction in paraplegic patients. But the inconstant anatomy of the vascular plexus around the gluteal muscle makes it hard to predict how many perforators are present, what their volume of blood flow and size are, where they exit the overlying fascia, and what their course through the muscle will be. Without any prior investigations, the reconstructive surgeon could be surprised intraoperatively by previous surgical damage, scar formation, or anatomic variants.For these reasons, to confirm the presence and the location of gluteal perforators preoperatively we have used color Doppler ultrasonography. With the help of the color Doppler ultrasonography 26 patients, 21 men and 5 women, were operated between the years 2002 and 2007. The mean age of patients was 47.7 (age range: 7-77 years). All perforator vessels were marked preoperatively around the defect locations. The perforator based flap that will allow primary closure of the donor site and the defect without tension was planned choosing the perforator that showed the largest flow in color Doppler ultrasonography proximally. Perforators were found in the sites identified with color Doppler ultrasonography in all other flaps. In our study, 94.4% flap viability was ensured in 36 perforator-based gluteal area flaps. Mean flap elevation time was 31.9 minutes. We found that locating the perforators preoperatively helps to shorten the operation time without compromising a reliable viability of the perforator flaps, thus enabling the surgeon easier treatment of pressure sores.

Magnetic resonance imaging assessment of gluteal fat grafts.

BACKGROUND: One goal of lipoplasty is to create a round and projected buttock contour. Despite multiple papers evaluating lipoinjection, controversies still remain. METHODS: This report describes a series of patients who underwent liposuction, gluteal lipoinjection, and evaluation with magnetic resonance imaging (MRI). From January 2003 to January 2004, the patients scheduled for contour surgery by the investigators were evaluated using MRI, photographic records, and gluteal circumference measurement 1 week before surgery, then 2 weeks and 3 months after the procedure. A statistical analysis was performed for 10 patients who received, on the average, a 350-ml injection of fat obtained during liposuction. RESULTS: Gluteus muscle volume increased, reaching a higher level 2 weeks after the injection than the level 3 months afterward (p < 0.001). The gluteal circumference, modified 2 weeks after surgery by about 1 to 3 cm, came back to previous values 3 months after the procedure (p < 0.05), a phenomena interpreted as reabsorption and resolution of the postoperative edema. There is no correlation between the gluteus muscle volume obtained by MRI and the gluteal circumference (p > 0.05). CONCLUSIONS: The findings led to the conclusion that enhancement of the gluteal contour after fat injection results from survival of the injected tissue 3 months after the surgery, which was objectively evaluated by MRI as having a calculated reabsorption rate of 24% to 36%.

Contouring the female buttocks. Liposculpting the buttocks.

Body sculpting has progressed during the past decade to a point where cosmetic units may be sculpted to improve contours which blend imperceptibly and appropriately with adjacent cosmetic units. The buttocks is ideally suited for sophisticated contouring as its frame is determined by the hips, thighs, and lower back and its proportions are balanced by the anterior projection of the breasts. In addition, ethnic differences in the shape and proportions of the buttocks create a variety of aesthetically pleasing variations in size and shape. The article attempts to elucidate these considerations combined with a logical surgical approach to achieve pleasing results in body sculpting.
