Gluteoplasty (gluteal augmentation) procedures are increasing in popularity, but there is not a universally accepted technique to produce optimal outcomes while minimizing risk. In this systematic review, we perform a meta-analysis to evaluate rates of complication from autologous fat grafting, implants, and local flaps, which are the three most common gluteoplasty operations.
A search of the PubMed/MEDLINE database for articles including the terms "gluteoplasty" OR "gluteal augmentation" OR "buttock augmentation" OR "Brazilian butt lift" OR "gluteal autologous fat graft" OR "buttock autologous fat graft" OR "gluteal implant" OR "buttock implant" OR "gluteal flap" OR "buttock flap" generated 229 articles. This number was brought down to 134 after initial screening by title. Inclusion criteria then removed those not written in English, those without access to the full text, those without extractable data on complications, and duplicates, leaving 46 articles to examine.
A total of 4362 patients who underwent gluteoplasty between 1992 and 2017 were found. The overall complication rate was 12.4%. Implants had the highest rate (31.4%), whereas fat grafting had the lowest (6.8%); flaps were intermediate (23.1%). A χ test yielded a statistically significant (P < 0.001) nonindependent relationship between combined complication rate and type of surgery. Individual complications, such as asymmetry, capsular contracture, fat embolism, hematoma, infection, necrosis, pain, seroma, wide scar formation, and wound dehiscence, were also analyzed.
Fat grafting by plastic surgeons might be the best option for gluteoplasty with regard to complications. In certain cases, however, there may only exist one choice for an operation because of anatomical limitations, which predisposes patients to those associated complications.
臀成形术（丰臀术）越来越受欢迎，但目前尚无一种普遍接受的技术能在将风险降至最低的同时产生最佳效果。在本系统评价中，我们进行了一项荟萃分析，以评估自体脂肪移植、植入物和局部皮瓣这三种最常见的臀成形术的并发症发生率。
在PubMed/MEDLINE数据库中搜索包含“臀成形术”或“丰臀术”或“臀部增大术”或“巴西提臀术”或“臀自体脂肪移植”或“臀部自体脂肪移植”或“臀植入物”或“臀部植入物”或“臀皮瓣”或“臀部皮瓣”等术语的文章，共检索到229篇文章。经标题初步筛选后，数量降至134篇。纳入标准随后排除了非英文撰写的文章、无法获取全文的文章、没有可提取并发症数据的文章以及重复文章，最终留下46篇文章进行审查。
共发现4362例在1992年至2017年间接受臀成形术的患者。总体并发症发生率为12.4%。植入物的发生率最高（31.4%），而脂肪移植的发生率最低（6.8%）；皮瓣的发生率居中（23.1%）。χ检验显示联合并发症发生率与手术类型之间存在统计学显著（P < 0.001）的非独立关系。还对个体并发症进行了分析，如不对称、包膜挛缩、脂肪栓塞、血肿、感染、坏死、疼痛、血清肿、广泛瘢痕形成和伤口裂开。
就并发症而言，整形外科医生进行的脂肪移植可能是臀成形术的最佳选择。然而，在某些情况下，由于解剖学限制，手术可能只有一种选择，这使患者易发生相关并发症。
