Open Reduction Internal Fixation of Condylar Head/Diacapitular Fracture of Mandible: Case Series.

Objective: Surgical management of condylar head is largely deferred due to the lack of appropriate armamentarium or instrumentation, restricted surgical access and risk of iatrogenic complications. Here we delineate open reduction internal fixation of condylar head fracture with various fixation modalities using specialized instrumentation for visualization and providing access for reduction with minimal complications.

Methods: A total of 21 patients were reported with condylar head fracture of mandible to the Department of Oral and Maxillofacial Surgery from January 2017 to June 2018. Three patients had bilateral condylar head fracture, making it a total of 24 fractures. All patients had clinical symptoms including deranged occlusion, limited mouth opening, jaw deviation and restricted mandibular movements. The radiological findings were dislocated or displaced condylar head medially or laterally. All patients were treated by open reduction internal fixation using lag screws or standard long screws.

Results: Among condylar head fractures, 19 of the study population were male and 2 were female. Distribution of age among the condylar head fractures ranges from 19 years to 40 years with the mean being 22 years. At the end of three-month follow-up, all patients had satisfactory results, both clinically and radiologically. The functional outcome of this study was found to be superior.

Conclusion: We recommend open reduction internal fixation of condylar head for patients with high risk of ankylosis, and it is possible without complications due to the availability of minimally invasive surgical access system.
