BREAST LIFT MASTOPEXY The breast lift procedure, or mastopexy, is usually performed to correct the forces of gravity or aging or after pregnancy and nursing. As the skin loses elasticity, the breasts often lose their shape and firmness and begin to sag. This surgical procedure raises and reshapes sagging breasts. Mastopexy can also reduce the size of the areola, the darker skin surrounding the nipple. If your breasts are small or have lost volume, breast implants inserted in conjunction with mastopexy can increase both their firmness and size.
