Management of the male pectoral region to obtain a natural but athletic contour through liposuction is constantly changing, but no single method can avoid all long-term problems, such as gynecomastia with eventual loss of pectoral definition, fat graft asymmetry, and/or unnatural definition.
The aim of this article was to describe a surgical technique to improve the male pectoral region through liposuction in specific areas, muscular volumization with objectively established fat volumes based on intracompartmental pressure measurements, and the management and prevention of gynecomastia. This approach aims to ensure the maximal survival of the fat graft with reduced fat necrosis and long-term asymmetry, producing sustained results over time.
Measurement of pectoralis major pressure after fat grafting was conducted in 150 patients (19-60 years old; BMI < 30 kg/m2) between January 2021 and June 2023.
The 2 models used in this study exhibited strong explanatory power, indicating that a significant portion of the variability in fat graft resorption could be explained by the variables included in these models. Postoperative exercise, patient age, and intramuscular pressure of the transferred fat showed statistically significant correlation with fat graft survival. BMI did not show a statistically significant relationship. The established volumes did not exceed 8 mm Hg intracompartmental pressure. Higher volumes reduced fat survival. Large volumes led to greater postoperative asymmetry and loss of fat grafts.
This technique can treat and prevent gynecomastia while simultaneously improving the appearance of the male chest through volumization of the pectoralis major with safe fat graft volumes.
通过抽脂术来塑造男性胸肌区域,以获得自然且富有线条感的轮廓,相关方法在不断演变,但尚无单一方法能够避免所有长期问题,如乳腺增生导致胸肌轮廓最终消失、脂肪移植不对称和/或外形不自然。
本文旨在描述一种手术技术,通过特定区域的抽脂术、基于肌室内压力测量客观确定脂肪量来增加肌肉体积以及对乳腺增生进行管理和预防,以改善男性胸肌区域。该方法旨在确保脂肪移植的最大存活率,减少脂肪坏死和长期不对称问题,随着时间推移产生持续效果。
在2021年1月至2023年6月期间,对150名患者(年龄19 - 60岁;BMI < 30 kg/m²)进行了脂肪移植后胸大肌压力测量。
本研究中使用的两个模型具有很强的解释力,表明这些模型中包含的变量可以解释脂肪移植吸收变异性的很大一部分。术后运动、患者年龄和移植脂肪的肌内压力与脂肪移植存活率呈统计学显著相关。BMI未显示出统计学显著关系。确定的脂肪量不会使肌室内压力超过8 mm Hg。脂肪量越高,脂肪存活率越低。大量脂肪会导致术后更大的不对称和脂肪移植丢失。
该技术可以治疗和预防乳腺增生,同时通过安全的脂肪移植量增加胸大肌体积,改善男性胸部外观。
