Abdominoplasty is performed by making a horizontal incision just above the pubis. The length of the incision varies depending on the amount of excess skin to be removed. The excess skin and fat is pulled down and excised. An incision may also be necessary around the navel. The abdominal muscles are examined through the incision and can be tightened to improve the contour of the waistline. Liposuction can also be performed as an adjunct to the procedure.
