Clinical Outcome of Open Reduction and Internal Fixation of Mandibular Condyle Fracture: A Prospective Observational Study

Abstract

Introduction: Condyle of mandible plays crucial role in functioning of jaw. Untimely and inadequate treatment leads to deformity of face along with range of complications. The purpose of this study was to assess outcomes of open reduction and internal fixation of mandibular condyle fractures in terms of mouth opening, facial nerve function and occlusion.Methods: This was a prospective observational study conducted at Chitwan Medical College. Thirty-two patients of mandibular condyle fracture were treated by open reduction and internal fixation via retromandibular approach and evaluated for mouth opening, facial nerve function, and occlusion on 2nd day, 10th day and 25th day postoperatively. All collected data were entered on SPSS version 21 and analyzed using descriptive statistical methods. The results were presented as graphs and tables.Results: Of 32 patients, 7 patients show abnormal occlusion while 25 patients show normal occlusion. A gradual improvement in mouth opening and facial nerve function was also seen on 25th day.Conclusion: Open reduction and internal fixation gives superior clinical outcomes in terms of mouth opening, facial nerve function and occlusion. It also allows good anatomical repositioning and early function.Keywords: Facial nerve function, Mouth opening, Occlusion, Open reduction internal fixation Layman summary: The mandible is largest and strongest bone of face. However, it is also most common facial bone that is fractured. Condyle of the mandible is highly prevalent site of mandibular fracture. The fracture of mandible is managed by open or closed reduction. Both of the methods have their own merits and demerits. In this study, we planned to assess the outcomes of open reduction and internal fixation of mandibular condyle fractures at a tertiary care center of Nepal. We found that ORIF has a good clinical outcome in mandibular fracture in terms of mouth opening, facial nerve function and occlusion.
