Tummy Tuck & Lipo Dr. Mentz can achieve great results with liposuction alone, but liposuction cannot fix a lose abdominal wall. A tummy tuck is usually done in combination with liposuction to repair the abdominal muscles and tighten loose skin. Notice this patient’s beautiful curves and flat stomach. Dr. Mentz is usually able to hide the resulting scar from the tummy tuck below the panty line, as seen in these photos.
