A woman's breast is primarily composed of fatty tissue and mammary glands. Mammary glands drain into the lactiferous sinus, which connects them to the nipple. The nipple is encircled by a pigmented ring called the areola.
Women who are uncomfortable with the size, shape, or position of their breasts may elect to have breast augmentation with the insertion of breast implants. Breast implants come in many sizes, and they are usually filled with either saline or silicone gel. Today, saline implants are more commonly used.
Breast augmentation using saline implants requires only a small incision either below the breast, along the edge of the areola, or in the armpit. The implants consist of empty silicone sacks, which are inserted through the incision and positioned either below the chest muscle or between the muscle and the existing breast tissue. The sacks are then filled with a saline solution using a needle and syringe.
After a brief period of swelling and tenderness, the incision lines begin to fade and the breasts take on a more natural shape. There are several potential complications associated with this procedure that should be discussed with a doctor prior to surgery.
