Excision techniques are recommended where glandular breast tissue or excess skin must be removed to correct gynecomastia. Excision also is necessary if the areola will be reduced or the nipple will be repositioned to a more natural male contour. Incision patterns vary depending on the specific conditions and surgical preference.
