Male breast development refers to gynecomastia. Surgeries include post-liposuction circumareolar mastopexy, lumpectomy, and minimally invasive rotational mastopexy. 1. Liposuction post-circumareolar areola incision: it is necessary to make a longitudinal incision of 0.5 cm in the armpit, and then use a suction device to draw out the fat, and then make a circumareolar incision of 1.5~2.0 cm under the areola, and then enter the scissors through the incision to cut the gland into strips and then remove it. 2. Lumpectomy: It is necessary to suction out the fat first, and then put in the lumpectomy through the axillary incision. Under the assistance of the lumpectomy, the fibrous tissue between the skin and the gland is cut off and the gland is removed. 3. Minimally invasive rotary excision surgery: it is necessary to make a point-shaped incision close to the nipple near the axillary side, first suction the fat, and then under the guidance of color ultrasound, insert the minimally invasive rotary excision knife through the incision, and then excise the gland layer by layer. Once the patient goes to the hospital for a relevant examination, the doctor will take into account the specific situation and recommend the appropriate surgical method.
