Failure Analysis of the Superior Lateral Plate Technique for Mandibular Angle Fractures

Abstract

The mandibular angle is often found to be the second most common site of mandible fractures following condylar fractures and consists of up to 25% of all mandible fractures, according to Fonseca. Mandibular angle fractures are also known to be the most common site for postoperative complications as with a complication rate reported of up to 30%. Our institution has been treating angle fractures with open reduction and single plate fixation at the superior lateral border utilizing a trans-buccal approach. Other fixation options include a superior border miniplate (Champy technique), 2 miniplate fixation and inferior border fracture or reconstructive plate via a transfacial approach. Previous studies (Ellis) have shown the superior lateral technique was found to be favorable. This study aims to examine current data and review the variables that may contribute to the observed complications in mandibular angle fractures.
