Evaluation of mandibular fracture treatment.

A total of 124 patients treated for mandibular fractures were analyzed. Patients were divided into three groups according to treatment: intermaxillary fixation, wire fixation and mini-plate fixation. For each method, the success of treatment was evaluated with respect to surgical approach, fracture site and injury to treatment interval. Five basic parameters were used for evaluation of the outcome: occlusion, appearance, mastication, duration of IMF and complications. The treatment was surveyed based on both the surgeon's and patient's-evaluation. All parameters were scored and average values for every parameter calculated. The most successful treatment was achieved with mini-plate fixation in symphyseal and angle fractures. Intermaxillary fixation is indicated for mandibular body fractures with or without minimal displacement and a sufficient number of teeth. However, mini-plate fixation should be used for fractures with displacement. Wire fixation has been shown to be the poorest choice for all sites. Results showed that the intraoral approach has advantages over the extraoral one. The optimal time for treatment of mandibular fractures is within 72 h from time of injury. Even in fractures older than 7 days we recommended mini-plate fixation.
