Gynecomastia is a benign clinical condition that is the unilateral or bilateral enlargement of the male breast, but sometimes it causes serious psychological and physical stress in young men and brings about phobia of malignancy in elderly men. Minimally invasive and functional therapy represents an inevitable trend in breast surgery. We investigated the feasibility and safety of vacuum-assisted biopsy device in treating gynecomastia.


From January 2006 to January 2010, 20 male patients with gynecomastia were treated by an 8-gauge vacuum-assisted biopsy device. The average age was 24.7 years (range, 18-47 years).


The operation was successfully performed in all 20 patients with a mean operating time of 51 minutes and a hospital stay of 4 days. Postoperative complications included 1 case of hematoma, but no nipple necrosis, local skin necrosis, or skin buttonhole occurred. No other operation-related complications were observed. Satisfactory chest contour was gained in all cases without any abnormality, skin redundancy, or recurrence during the follow-up of 6-48 months.


Treatment of gynecomastia by the Mammotome device is distinctive, practicable in manipulation, safe, and can achieve excellent cosmetic results. The Mammotome procedure simply represents another novel treatment option for gynecomastia.
