Accessory breasts are mainly classified into gland type and adipose type. Due to the extremely low proportion of adipocytes, gland typed accessory breasts mostly necessitate direct excision to achieve obvious improvement. Adipose typed accessory breasts comprise 70% of fat globules and mostly feel loose and soft, so they can be rapidly and effectively corrected by liposuction. At present, for the treatment of adipose accessory breasts, WiSH Clinic adopts the latest Ultra-Z liposuction method, which only requires creating a 0.5-cm incision at the armpit. Dr. Chuang first guides a special ultrasonic lipolysis probe into the adipose layer of the accessory breast, then emulsifies the fat globules and small parts of mammary tissues by the vibration and thermal effect of the high-frequency ultrasonic wave, and finally suctions fats by a negative pressure liposuction machine. Ultra-Z liposuction not only completely removes superficial fats but also prevents postoperative skin laxity; thus, it is the most effective accessory breast liposuction method.
