Abstract

Background: In order to obtain a natural but athletic contour through liposuction, the management of the male pectoral region is constantly changing. Cutting-edge methods including mammary gland excision and fat grafting to the pectoralis major have been created. There isn't yet a single method that can handle all long-term problems, like gynecomastia with eventual loss of pectoral definition, fat graft asymmetries, and/or unnatural definition..vic.

Objectives: This article proposes a surgical technique to improve the male pectoral region through liposuction in specific areas, muscular volumization with objectively established fat volumes based on intracompartimental 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, long-term asymmetry, and sustained results over time.

Methods: Measurement of the pectoralis major pressure, following fat graft, was conducted between January 2021 and June 2023. Patients aged between 19 and 60 years at the time of surgery, with a body mass index below 30 kg/m², were included. The surgical technique is presented in this article.

Results: The two 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, patients age, and intramuscular pressure of the transferred fat showed statistically significant results in the survival of fat grafts. BMI did not show a statistically significant relationship.

Conclusions: 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 grafts volumes. The established volumes did not exceed 8 mmHg intracompartimental pressure. Higher volumes reduced fat survival. Large volumes lead to greater postoperative asymmetry and loss of fat grafts.
