Background: Some people have a "bat wing" deformity and an extension of skin redundancy from the axilla along the lateral chest wall that overlaps in the breast region, which has an effect on surgical choices. Forearm redundancy can also occur in certain people. Objectives: To evaluate the aesthetic outcome and complications of brachioplasty in post massive weight loss patients. Patients and methods: This is a prospective comparative study conducted on 24 patients with brachioplasty; to evaluate the aesthetic outcome and complications of brachioplasty in postoperative weight loss patients, in the Plastic Surgery Department of Menoufia University and Maadi Military Hospital, during a period time from April 2019 to October 2022. Results: According to Spearman's correlation analysis, there was a highly significant positive association between preoperative average arm circumference and postoperative arm circumference (p <0.01). All three procedures displayed non-significant predictive results when separating patients with reduced arm circumference from those without (p > 0.05) using ROC-curve analysis. By using ROC-curve analysis, mini brachioplasty technique predicted complications-free patients with good (82.5%) accuracy, sensitivity= 100% and specificity= 65% (p = 0.0002). Conclusion: In certain patients with generalised inferior arm skin and fat redundancy, a brachioplasty surgery is an effective and repeatable therapy. The markers and resection are made simpler. By protecting lymphatics and nerves and reducing blood loss, it offers a safe process. It generates consistent, foreseeable consequences with reliable performance.
