It is performed to treat “pseudogynecomastia” which is caused by obesity but not truly mammary gland hyperplasia. Male patients with abnormal breast enlargement due to fat accumulation or obesity mostly do not experience any symptoms and only have relatively protruded breasts such as females. Because majority of the breast is composed of fat, simple breast liposuction can be effective. A 3-mm incision is made at the periphery of the breast, and the same Ultra-Z ultrasonic machine is used to emulsify and suck the fat, creating an almost flat chest. A pressured chest bandge or spandex needs to be worn after surgery to prevent the loosening of chest skin.
