From the photos, there is abdominal skin laxity and contour change, but the need for muscle repair cannot be confirmed from photos alone. Muscle repair during a tummy tuck is usually recommended when there is rectus diastasis, meaning separation or stretching of the abdominal muscles, which is checked by physical exam while you tighten your abdomen. If diastasis is present, repairing it can help flatten the abdominal wall and improve waist contour. If the muscles are not separated, a tummy tuck may focus more on skin removal, scar placement, and limited fat contouring. An in-person exam with a board-certified plastic surgeon is the right way to decide whether muscle repair is truly needed in your case.
