RESUMO

BACKGROUND: The objective of this study is to report the outcomes of a modified comprehensive Apert syndrome surgical protocol in which fat injection was performed during early infancy concurrent with postposterior vault distraction osteogenesis (PVDO) distractor removal. METHODS: A retrospective study was performed on 40 consecutive young patients with Apert syndrome who underwent PVDO and subsequent distractor removal between 2012 and 2022. Of these 40 patients, 12 patients underwent facial fat injection concurrent with distractor removal to treat residual supraorbital bar recession as part of a modified comprehensive Apert syndrome surgical protocol. Preoperative and postoperative severity of recession and irregularity was graded from 1 to 3, with 1 being less severe and 3 being the most severe. Recession severity was correlated with the number and type of suture fusion. The complication rate was stratified via a Clavien-Dindo scale. RESULTS: The average patient age was 14.3±5 months, with 5 males (41.6%) and 7 females (48.3%). The average hospital stay was 1.08 days. The average volume of free fat graft injection was 8.29±5 mL. According to the Likert scale, forehead morphology improved in 91.67% of the patients. Complete resolution of supraorbital bar recession was achieved in seven patients (58.33%), all of whom presenting a single suture synostosis. One patient with a cloverleaf skull presented a type IIIB complication. CONCLUSIONS: Facial fat grafting markedly reduces forehead asymmetry and improves forehead contour in Apert syndrome patients following PVDO. Total resolution of forehead recession directly correlated with a single suture fusion.

RESUMO

BACKGROUND: The BAAPS advice against Brazilian butt lift (BBL) surgery in the UK was set in October 2018. A Delphi study conducted by BAAPS highlighted the importance of defining current practice and perceptions amongst UK surgeons, as this is currently unknown. OBJECTIVES: To evaluate BAAPS members' current practice and perceptions around BBL surgery to ensure patient safety and propose better recommendations. METHODS: A BAAPS-commissioned survey was emailed to all BAAPS members through an on-line link. The survey collected quantitative and qualitative information in several domains. RESULTS: This survey received a 44% response rate. Of 102 respondents, 32 surgeons undertook BBL surgery before the BAAPS advice to halt it. There was a wide variation in actual fat volumes injected, and in perceptions of what constituted a small or large volume. Virtually all respondents (96.9%) performed only subcutaneous fat injections. There were differences in fat harvest techniques. The majority (66.7%) felt that BAAPS should maintain its recommendation against undertaking BBL surgery until further data became available. Nearly a quarter of 102 respondents (20.6%) had been treated for BBL complications, the majority as a result of surgical tourism. CONCLUSIONS: The survey provides member-reported perception and experience with regard to BBL surgery in the UK. The demand for BBL surgery and its provision should be reassessed in the UK. This information will be analysed with further national and international data to better define and shape the scope of the safety of BBL surgery in the UK. BAAPS will use such data towards the production of future guidance and support for surgeons and patients.

RESUMO

BACKGROUND: Gluteal fat augmentation has increased worldwide, and so have major complications. Brazilian plastic surgeons have been performing this procedure for more than 30 years, and more often every year. Therefore, the authors performed a study among board-certified plastic surgeons, members of the Brazilian Society of Plastic Surgery, to evaluate their techniques; identify their preferences, complications, and outcomes with this procedure; and make some recommendations. METHODS: An anonymous Web-based survey consisting of 16 questions was sent to 5655 members in July of 2017. A supplementary survey was subsequently sent to obtain more information about major complications. RESULTS: A total of 853 responses were analyzed. The highest percentage of responses in the different categories were as follows: fat decantation for processing, injection with a 3-mm-diameter cannula, use of superior incisions, subcutaneous fat grafting only, and with a volume of 200 to 399 ml of fat per buttock. The majority of surgeons received training in this procedure during residency. The most common complications were contour irregularities. The estimated mortality rate was one in 20,117 cases, and the rate of nonfatal fat embolism was one in 9530. The risk of death was 16 times greater when fat was injected intramuscularly. CONCLUSIONS: Based on this survey, the authors recommend injecting fat only subcutaneously, by means of superior incisions, using cannulas 3 mm in diameter or more. They find that by following these recommendations, this procedure can be as safe as any other. More research to establish guidelines and increase its safety is necessary.

RESUMO

BACKGROUND: Laboratory reports on adipose tissue suggest that fat grafting to the breast may pose an oncologic risk. One possible reason for this is the theoretic chronic inflammation due to adipokynes released by grafted white adipose tissue (WAT). OBJECTIVES: The aim of this study was to analyze inflammatory activity in lipofilled breast through the use of proinflammatory markers. METHODS: Fifty-four paired-breasts of female rats were divided into 4 groups: control, sham, and breasts grafted with either autologous subcutaneous (SC) WAT or autologous omentum (OM). The WAT was prepared through centrifugation, and the grafting was performed with the use of 0.9-mm blunt-tip cannula. The rats were killed 8 weeks postoperatively, and their breasts were harvested for immunohistochemical staining for CD68-expressing macrophages, gene expression (real-time PCR) for monocyte chemoattractant protein 1 (MCP-1), F4/80, Cox-2, and IL-6. RESULTS: The weights of the rats that underwent a procedure differed from those of the unmanipulated control group (P < 0.01). The macrophage counts of CD68 differed only between breasts lipofilled with OM and control (P < 0.01). MCP-1, F4/80, and Cox-2 were similarly expressed among the groups (P = 0.422, P = 0.143, and P = 0.209, respectively). The expression of IL-6 differed between breast samples grafted with SC and OM WAT (P = 0.015), but not between samples of control and OM (P = 0.752), and control and SC (P = 0.056). CONCLUSIONS: No inflammation activity was identified in the microenvironment of lipofilled breasts, indicating that chronic inflammation does not seem to be triggered by the breast lipofilling procedure.

RESUMO

Background: Fat grafting for gluteal augmentation is one of the most popular aesthetic surgery procedures. It has an associated mortality to fat embolism of 0.2%. Objectives: The authors of this study sought to describe which technique for synthetic graft application was least likely to cause a fat embolism. Methods: Ten fresh bodies were obtained and 4 groups arranged with 5 buttocks each randomly assigned. Group 1 was infiltrated through the upper medial intergluteal sulcus (upper medial intergluteal sulcus) with an angulation of -30°, -10°, and 0°. Group 2 was infiltrated through the middle lower gluteal sulcus with an angulation of -30°, 0°, and +15°. Group 3 was infiltrated through a peritrochanteric (PT) access at the level of the femur head at 0° and +10° and in the middle of the buttock at the level of the posterior superior iliac crest at -30° toward the trochanter (lateral direction). Group 4 was infiltrated in the same manner as group 1 without -30°. A complication occurred when the graft was in contact with the vascular or nervous bundle, within the gluteus medius muscle, or both. Results: Group 1 had 3 buttocks with a complication (UMIGS -30°). Group 2 had complications in all the injection techniques. Group 3 had 5 buttocks with a complication (PT at 0°). Group 4 had no complications. Conclusions: The injection of the fat graft through the UMIGS at 0° and 10° angles, and through the middle of the buttock at the level of posterior superior iliac crest a -30° angle, reaches the surface needed for gluteal augmentation. The group 2 techniques should be avoided because they have a high risk of complication.

RESUMO

BACKGROUND: Cellulite is one of the most common skin and subcutaneous tissue conditions, affecting predominantly the thighs and hips in postadolescent women. Its etiology is not well defined, and multiple available treatments show variable efficacy. OBJECTIVES: To describe a technique for treatment of cellulite of the gluteal region, thighs, and hips through superficial liposuction utilizing a special cannula, combined with subcutaneous autologous fat grafting. METHODS: A retrospective review was performed of patients treated over 26 years at the Hospital São Lucas, Pontifical Catholic University of Rio Grande do Sul, Porto Alegre, Brazil. Patients underwent pretreatment evaluation as to the extent of their cellulite, and pretreatment and posttreatment photographs were obtained for visual evaluation of the results. RESULTS: Procedures were performed on 126 patients: 121 (96%) women and 5 (4%) men. The majority considered their results good or excellent. The complication rate was low, with the most common complications being ecchymosis, contour irregularities, partial recurrence of cellulite, seroma, and numbness. CONCLUSIONS: We describe an effective method for the treatment of cellulite. Whereas subcision techniques utilize a needle or microblade to cut fibrous septa, we utilize a special cannula; larger areas can be treated than with subcision. Fat grafting is utilized to correct depressions and improve skin quality, which are added benefits compared to traditional subcision. Considering the multiple available cellulite treatments and their limitations, and the high patient satisfaction rate we achieved, with a low recurrence and complication rate, this technique can be a safe and effective option for patients with cellulite.

RESUMO

Background: The results of experimental studies indicate that grafting of autologous adipose tissue may induce tumorigenesis at the recipient site, but clinical results do not support a carcinogenic effect of fat grafting to the breast. Objectives: The authors assessed cancer risk following transplantation of autologous fat into murine mammary tissue. Methods: In this animal study, mammary tissues from 54 breasts of 9 female rats were either grafted with autologous subcutaneous fat, grafted with autologous omental fat, or unmanipulated. Tissues were harvested and processed for histologic and immunohistochemical analyses, and the mRNA expression levels of specific genes were determined. Results: No atypia or changes in lobular structures were observed in lipofilled breasts compared with controls. The numbers of ductal cell layers and terminal ductal units were similar for lipofilled and control breasts. Macrophage concentrations also were similar for the 3 groups. The localization and magnitude of plasminogen activator inhibitor 1 were similar for lipofilled and unmanipulated breast tissue. The percentages of cells expressing Ki67 or estrogen receptor (ER) and the ER/Ki67 balance were similar for the 3 groups. Gene expression was not altered in lipofilled breasts, compared with controls. Conclusions: No theoretical risk of cancer was detected in the microenvironment of the lipofilled rat breast.

RESUMO

Long-term dietary and pharmacological treatments for obesity have been questioned, particularly in individuals with severe obesity, so a new approach may involve adipose tissue transplants, particularly autologous transplants. Thus, the aim of this study was to evaluate the metabolic effects of autologous subcutaneous adipose tissue (SAT) transplants into two specific intraabdominal cavity sites (omental and retroperitoneal) after 90 days. The study was performed using two different diet-induced obesity (DIO) rat models: one using a high-fat diet (HFD) and the other using a high-carbohydrate diet (HCHD). Autologous SAT transplant reduced hypertrophic adipocytes, improved insulin sensitivity, reduced hepatic lipid content, and fasting serum-free fatty acids (FFAs) concentrations in the two DIO models. In addition, the reductions in FFAs and glycerol were accompanied by a greater reduction in lipolysis, assessed via the phosphorylation status of HSL, in the transplanted adipose tissue localized in the omentum compared with that localized in the retroperitoneal compartment. Therefore, the improvement in hepatic lipid content after autologous SAT transplant may be partially attributed to a reduction in lipolysis in the transplanted adipose tissue in the omentum due to the direct drainage of FFAs into the liver. The HCHD resulted in elevated fasting and postprandial serum insulin levels, which were dramatically reduced by the autologous SAT transplant. In conclusion, the specific intraabdominal localization of the autologous SAT transplant improved the carbohydrate and lipid metabolism of adipose tissue in obese rats and selectively corrected the metabolic parameters that are dependent on the type of diet used to generate the DIO model.
