Abdominoplasty or tummy tuck is a cosmetic surgery procedure used to make the abdomen more firm. The surgery involves the removal of excess skin and fat from the middle and lower abdomen in order to tighten the muscle and fascia of the abdominal wall. This type of surgery is usually sought by patients with loose tissues after pregnancy or individuals with sagging after major weight loss.Abdominoplasty operations vary in scope and are frequently subdivided into categories. Depending on the extent of the surgery, a complete abdominoplasty can take 1 to 5 hours. A partial abdminoplasty (Mini-Tuck Abdominoplasty) can be completed between 1 to 2 hours.
