Abdominoplasty-Systematization of a technique without external umbilical scar

The author describes an abdominoplasty emphasizing preparation of the abdominal flap, reinforcement of the muscular aponeurotic wall, treatment of the excess of cutaneous tegument, and careful handling of the umbilicus. He makes three umbilical flaps which are alternately stitched to three other flaps originating on the abdominal wall, which result in a scar hidden inside the umbilicus.
