A plastic surgery thigh lift can be performed to tighten sagging muscles and remove excess skin in the thigh area. Because a thigh lift leaves noticeable scars in the inner or outer thigh area, some patients find the thigh lift procedure undesirable. A thigh lift is often performed to correct sagging skin or loose skin in the inner and outer thighs, as well as to remove excess fat deposits and improve thigh contours. It is not uncommon for a thigh lift to be performed as part of a total body lift or lower body lift combination surgery.
