A horizontal cut (called an osteotomy) is made through the jaw bone (mandible) with a bone saw or chisel. The lower portion of the separated bone is moved forward to the desired position and wired in place. The neurological nerves are carefully protected. The incision is closed with sutures and an external pressure dressing is applied. There is no visible scarring since the surgery is performed through an incision inside the mouth.
