If excess glandular tissue is the primary cause of the breast enlargement, it will be excised, or cut out, with a scalpel. The excision may be performed alone or in conjunction with liposuction. In a typical procedure, an incision is made in an inconspicuous location–either on the edge of the areola or in the under arm area. Working through the incision, the surgeon cuts away the excess glandular tissue, fat and skin from around the areola and from the sides and bottom of the breast. Major reductions that involve the removal of a significant amount of tissue and skin may require larger incisions that result in more conspicuous scars. If liposuction is used to remove excess fat, the cannula is usually inserted through the existing incisions.
If your gynecomastia consists primarily of excessive fatty tissue, your surgeon will likely use liposuction to remove the excess fat. A small incision, less than a half-inch in length, is made around the edge of the areola–the dark skin that surrounds the nipple. Or, the incision may be placed in the underarm area. A slim hollow tube called a cannula which is attached to a vacuum pump, is then inserted into the incision. Using strong, deliberate strokes, the surgeon moves the cannula through the layers beneath the skin, breaking up the fat and suctioning it out. Patients may feel a vibration or some friction during the procedure, but generally no pain.
