Clinically, the cost of gynecomastia surgery varies depending on the level of the hospital where the patient is seen. First of all, if the patient’s hospital is a Level II-A hospital, the cost of gynecomastia surgery is about$5,000. The second is that if the patient is in a tertiary care hospital, the cost of gynecomastia surgery is about$8,000. Depending on the extent of the patient’s condition and the speed of recovery after surgery, the patient’s cost will fluctuate. Gynecomastia surgery is preceded by an accurate surgical evaluation of the patient to achieve precise removal. It is important to remove the patient’s breast gland while ensuring that the patient’s breast flap does not necrotize and that the patient’s nipple functions. It is important to note that for gynecomastia surgery, subcutaneous drainage must be performed to prevent the occurrence of subcutaneous fluid in the breast in order to facilitate the patient’s postoperative recovery.
