The aesthetics for the male posterior torso remain a topic not fully studied in body contouring surgery, neither the lipoinjection of its muscles have been considered before. As a result, we carried out a retrospective cohort study including patients who underwent fat grafting of either the trapezius or the latissimus dorsi muscles as part of dynamic definition liposculpture (HD2).
Methods: We performed cadaveric dissections to support the fat grafting technique for both the trapezius and the latissimus dorsi muscles. We also searched our records for patients who underwent fat grafting of these muscles in addition to HD2 from January 2016 to November 2021 at a single center in Bogotá, Colombia.
Results: Thirty-five consecutive patients met the inclusion criteria. In total, 22 (63%) and 7 (20%) of 35 underwent fat grafting at the trapezius and the latissimus dorsi muscles alone, respectively, and 6 out of 35 (17%) of both. Mean age is 39 years (range = 22-63). All patients were men. No complications were recorded related to fat grafting. Almost all patients were satisfied with the procedure (97%). Follow-up period ranged from 2 to 48 months.
Conclusions: Liposuction might not be enough to achieve the ideal V-shape of the men's back in some cases; hence, fat grafting of the power muscles becomes the best option. Recognition of the main neurovascular pedicle, proper preoperative markings, and a correct surgical technique ensure both the safety and the reproducibility of the technique.
