Management of Mandibular Sub Condylar and Condylar Fractures Using Retromandibular Approach and Assessment of Associated Surgical Complications

Purpose: To evaluate surgical complications associated with open reduction and internal fixation of condylar fractures using retromandibular approach in terms of intraoperative and postoperative complications. Method: Ten patients with displaced unilateral/bilateral condylar fractures were selected for the study. Intraoperative complications were evaluated in the form of haemorrhage due to damage to retromandibular vein and damage to marginal mandibular branch of facial nerve. Postoperative complications like presence of infection, signs of Frey’s syndrome, parotid fistula formation, facial nerve palsy, and discrepancy in occlusion and functions of temporomandibular joint were evaluated at intervals of 24 h, one week, six weeks and three months postoperative. Radiographically, the approximation of fracture fragments, plate fracture and screw loosening on orthopantomograph and Reverse Towne’s view were evaluated at intervals of 24 h, six weeks and three months postoperatively. Results: None of the patients suffered from any major complication intra and post operatively. Conclusion: Open reduction and internal fixation should be given due consideration in the management of displaced mandibular condylar fractures and is associated with minimal morbidity using retromandibular approach. © 2011, Association of Oral and Maxillofacial Surgeons of India.
