Summary

Fractures involving the anterior transition zone of the mandible are frequently encountered and hold particular clinical significance due to the presence of the mental nerve. Consequently, mental nerve paresthesia is among the common postoperative complications associated with these fractures. To assess the mental nerve functional integrity during fixation of fractures at the anterior transition zone using twin fork-miniplate, 3d interlocking miniplate and two miniplates

Detailed description

A total of 36 patients (they were divided into three groups 16 patients in each group ) with parasymphyseal-body fractures , one group was treated with twin-fork miniplate , the second group was treated using 3d interlocking miniplate and the third one was treated with conventional two miniplates. Postoperative evaluation of the mental nerve was conducted using both subjective and objective methods at intervals of 24 hours, and at 1, 4, 6 and 12 weeks. Furthermore, an electrophysiological study was performed at 6 weeks postoperatively to measure the mental nerve's amplitude, onset latency and conduction velocity
