Ultrasound-guided Fat Graft of the Obliques–Serratus Complex

BACKGROUND: The idea of the anterolateral thoracic musculature in men during the contour procedure is very limited, particularly in terms of surgical techniques that improve its appearance and aesthetics. Therefore, this study aimed to describe a technique of deep definition liposuction with intramuscular grafting of the serratus external oblique muscle complex. METHODS: A retrospective case series of a total of 11 cases of male patients aged between 29 and 60 years in the year 2022 is presented. These patients underwent body contouring surgery and subsequently underwent ultrasound-guided intramuscular fat grafting in the serratus external oblique complex. As part of the study, measurements were taken before and immediately after surgery. The data were stored in a database and analyzed with the statistical software SPSS, v23.0. RESULTS: The patients were aged between 29 and 60 years, with a mean age of 38.3 years (±8.5). All cases had a body mass index of 30. Results were matched preinfiltration and postinfiltration; These results were subjected to statistical validation using the Student t test for related samples, and statistically significant differences were obtained in all the measures tested. CONCLUSIONS: The technique of fat grafting in the oblique-serratus complex allows for increasing muscle thickness. The measurements were made only immediately after the infiltration; it is important in the future to show the long-term follow-up. No adverse events occurred during the study.
