Abstract: PURPOSE: To evaluate the epidemiology and the treatment of infected fractures of the mandible. METHODS: Thirty-five cases of infected mandible fractures treated by extra oral open reduction and rigid internal fixation with reconstructive plates were retrospectively investigated. RESULTS: The fracture healing and occlusion recovery of 34 cases were satisfied without any nonunion or deformity, except 1 case healed after bone grafting for bone defect. CONCLUSIONS：The reconstructive plate fixation is applicable to the treatment of infected mandible fractures by its excellent stability and reliability.
