Mandibular reconstruction using a free vascularised osteocutaneous flap from the internal condyle of the femur.

The authors present a preliminary report of a new microsurgical mandibular reconstruction procedure using a segment of the internal condyle of the femur as a free vascularised bone graft. It is possible to harvest a compound flap including a bony segment measuring 8 X 1.5 X 1.5 cm and a cutaneous saphenous flap with its nutrient pedicle arising from the descending genicular artery and vein. This surgical procedure provides a good cortico-cancellous bony segment and a separate skin flap. Dissection of the flap is sometimes difficult due to the inconsistency of its vascular anatomy; the donor site is left with minimal morbidity but, because of weakening of the femur, our patients are instructed not to return to full weight-bearing before the sixth postoperative week. We consider segmental reconstruction of the mandibular body to be one of the best indications for the flap.
