This surgery is applicable to patients with simple fatty breast tissue proliferation (adipose type) or obesity-induced pseudogynecomastia, which accounts for approximately 30% of all cases of gynecomastia. The characteristics of gynecomastia are that the male chest texture is as soft as the female breast and that it is usually combined with whole body obesities. Procedures are similar to those of female accessory breast liposuction. A 2-mm incision is made at the inferolateral margin of the chest, and after hemostatics and painkillers are injected into the periphery of the mammary gland, liposuction tubes of diverse sizes are inserted into the subcutaneous layer for liposuction till the breast becomes flat. Dr. Chuang utilizes the latest Ultra-Z lipolysis machine that shatters the relatively hard fat and fiber tissues adjacent to the mammary gland via high-frequency ultrasound waves, which completely melts adipose cells before they are aspirated. This not only effectively removes very superficial fats in copious amounts but also sculpts pectoralis lines to render more significant results.
