Abstract
Arm contouring usually represents a challenge for the surgeon due to zones with high risk of irregularities/asymmetries, the variable degree of skin laxity, and the differences between patient/gender preferences. In men, the bigger and muscular the arms the better, while women tend to prefer a slim and soft silhouette. METHODS: We performed arm cadaveric dissections and also searched our records for patients who underwent fat grafting of the arm in addition to HD2, from January 2016 to May 2022 at a single center in Bogotá, Colombia. RESULTS: Two hundred eighty-nine consecutive patients (275 men and 14 women) underwent high-definition lipoplasty/HD2 plus fat grafting of the biceps (72 muscles), the triceps (46 muscles), the deltoids (426 muscles), or a combination of them. Mean age was 39 and 36 years for men and women, respectively. Range of the fat graft volume was 30-150 ml. No major complications were reported. Follow-up period ranged from 2 to 24 months. Most patients were satisfied with the results. CONCLUSIONS: Men usually seek an overall well-toned and muscular extremity, while women tend to prefer a slim but also athletic contour. Such outcomes can be achieved through intramuscular fat grafting of the biceps, triceps, and deltoids. The proper recognition of the pedicles and a precise surgical technique will ensure both its safety and the reproducibility of the results.
