ABSTRACT

Objective:To evaluate the clinical outcomes of 2 kinds of osteocutaneous flap in the treatment of mandibular osteoradione-crosis.Methods:35 cases with mandibular osteoradionecrosis were treated by partial mandibulectomy and bone graft according to de-fect size and patients'requirements.The defects in 7 patients were reconstructed with iliac osteocutaneous flap and 28 with fibular os-teocutaneous flap.All flaps and wounds were monitored regularly.Results:One flap with venin crisis was observed in the patients treated with iliac osteocutaneous flap,its skin island was failed but the bone graft was survived.In the fibular osteocutaneous flap group,3 flaps with vein crisis were observed.2 of them were failed and 1 was rescued after second surgery.The most common compli-cations were infection,delayed wound healing and scar.The appearance and function were all satisfied and limitation of mouth opening was improved after surgery.Conclusion:Both of fibular osteocutaneous flap and iliac osteocutaneous flap can be applied in the defect reconstruction of patients with mandibular osteoradionecrosis.Fibular osteocutaneous flap is a good choice for huge mandibular defect and iliac osteocutaneous flap seems more esthetical.
