A standard abdominoplasty is where an incision is made at the waist crease and also around the umbilicus (belly button or navel). The umbilicus is freed from its attachment to the abdominal skin all the way down to the abdominal wall to be re-positioned later on. An umbilicus is nothing more than a scar, a remnant of what once was where the fetal umbilical cord entered the abdominal cavity, carrying blood with oxygen and nutrition from the mother to the fetus.
