The free greater omental flap for treatment of mandibular osteoradionecrosis.
Osteoradionecrosis can involve the mandible following radical irradiation for treatment of oral cavity cancer. The radionecrosis of the mandible is often associated with severe intractable pain, local or extensive deformity, including pathologic fracture, orocutaneous fistula formation, and frequent loss of function. Treatment has ranged from analgesia and antibiotics to hyperbaric oxygen treatments to local or extensive sequestrectomies with partial or total mandibulectomy and restoration of tissue losses with unirradiated tissue. To our knowledge, this is the first report of the successful use of a free greater omental flap for immediate treatment of mandibular osteoradionecrosis and concomitant reconstruction. We found the omentum to be an excellent vascular bed that rapidly resolved the osteoradionecrosis and pain, promoted healing, and restored mandibular function with minimal discomfort to the patient.
