(1) Background: The increase in the number of bariatric surgery procedures has led plastic surgeons to look for new approaches to improve outcomes of body-contouring surgeries. A major concern in brachioplasty is the scarring process. Here, we propose a novel technique to minimize the incidence of pathological or unsatisfactory scars from brachioplasty. A video of the entire procedure is provided. (2) Methods: From January 2016 to August 2020, we performed the "Jaws" brachioplasty on 16 post-bariatric patients. We evaluated the effectiveness of the technique through pre- and postoperative assessments by patients and surgeons, the Vancouver Scar Scale, and the detection of major and minor complications within 12 months of follow-up. (3) Results: Thirteen patients were female and three were male, with a mean age of 32.5 ± 6.8 years (range: 22-47 years). The BODY-Q© Arms Section scores improved significantly, with no incidence of major or minor complications over 1 year of follow-up, and favorable aesthetic outcomes. (4) Conclusions: We believe that the "Jaws" technique is a valid contribution to post-bariatric surgery, as it aims to solve specific aesthetic problems of scarring from brachioplasty. The small number of patients does not allow the comparison of our original technique to others previously described in the literature.
