Abdominoplasty, known more commonly as a "tummy tuck," is a surgical procedure to remove excess skin and fat from the middle and lower abdomen and to tighten the muscles of the abdominal wall. The procedure can dramatically reduce the appearance of a protruding abdomen and restore its youthful contour. The stretch marks and dimpled skin that are typically located below the navel are eliminated. Frequently, a lengthy scar is required extending from hip to hip, but can be well hidden in most bikini lines.
