Abstract:
Objective To explore the clinical applicating and efficacy of free fibula osteomyocutane- ous flap in mandible defect reconstruction in osteoradionecrosis patients.Methods The mandible defects were reconstructed by free fibula flaps with or without muscle cuff.The soft tissue defects were repaired by skin paddles.Status of osteotomy in fibula and flap survival was recorded.The complication in recipient site and donor site,as well as mouth opening and occlusion were reviewed.Facial contour and chewing function after reconstruction were evaluated.Results Patients were followed up 3-16 months.4 free fibula flaps with muscle cuff and 5 without muscle cuff survived well.The size of mandible defects covered from 6cm to 17cm. And the harvested fibula flaps with length of 8.6-17cm were cut into 3 segments in 2 cases,and 2 segments in 5 cases.Fibula flap was divided into 2 segments and overlapped in 2 cases.No serious complication was oh- served in recipient site and donor site.Satisfying esthetic result and normal occlusiong of heath mandible were obtained in all cases.The degree of mouth opening was 2.5-3.3cm.Fair chewing function was revealed in re- constructive region after prosthesia repaired.Conclusion Free fibula osteomyocutaneous flap is relatively ideal reconstruction material of mandible defect in osteoradionecrosis patients for its high survival rate and well esthetic results.
