Adipose-type accessory breasts are composed of 70% fat globules, so they are loose and soft to touch. Liposuction can be efficiently applied to solve the problem. Currently, Dr. Chuang uses the newest Ultra-Z ultrasonic liposuction in such cases. Only one 0.5-cm incision in the axilla is needed. Then, a special ultrasonic probe enters the subcutaneous fat layer. It emulsifies fat particles and some mammary gland tissue with ultrasound shocking wave and heat, and the fat is laterally sucked out. This method not only allows a more thorough elimination of fat cells but prevents skin sagging after the procedure. It is the most effective surgery of accessory breast liposuction at present.
