Abdominoplasty, also known as tummy tuck involves the removal of excess skin and fat from the abdomen. When the excess fat and skin are removed, the skin is stretched tight over the stomach, resulting in an impressively flat abdomen. Abdominoplasty can be combined with liposuction and other fat removal surgeries. The full abdominoplasty is a procedure that lasts for about three hours. Two long incisions are made, one along the public bone and the other that frees your belly button from the surrounding tissue. The stomach muscles are tightened and excess fat and skin are removed, thus flattening the tummy.
