A panniculectomy is performed to remove the hanging pannus, or apron of skin, from the lower abdomen below the belly button. The excess skin and fat above the belly button are not removed. A panniculectomy is often performed on patients who are still significantly overweight but have skin irritation from their hanging skin. After surgery, these patients have less skin problems but have little improvement in the contour of their bellies. This is NOT the same procedure as an abdominoplasty, or tummy-tuck.
