Endoscopic subcutaneous mastectomy: A novel and effective treatment for gynecomastia

The aim of this study was to evaluate the procedure for and efficacy of endoscopic subcutaneous mastectomy for gynecomastia. Endoscopic subcutaneous mastectomy was performed on 100 benign, palpable breast enlargements in 58 male patients who were followed-up for 15-63 months. The surgery was conducted with the insufflation of CO₂ subdermally. No cases were converted to open surgery. The unilateral surgery time was 70-90 min. The mean volume of the resected tissue was 200 ml. All procedures were completed successfully, with satisfactory clinical effects and ideal esthetic results postoperatively. There were three cases (3%) of papillary epidermal partial necrosis; following removal of the dressing during the hospital stay, normal nipple sensation returned. Endoscopic subcutaneous mastectomy had good clinical effects and ideal cosmetic results and is an appropriate approach for gynecomastia.
