Abstract
BACKGROUND: To present a series of eighteen cases of displaced mandibular condylar fracture managed by extra-corporeal fixation. To evaluate the post operative results in terms of occlusal stability, temporomandibular joint function and radiological findings. METHODS: A series of 18 cases were treated with extra corporeal fixation with mini plate and screws for displaced mandibular condylar fracture. Ramus was exposed through sub mandibular approach. A wire was passed through the angle of mandible to pull the mandible inferiorly. The displaced condyle was retrieved. A suitable bone plate was fixed to the condylar segment and it was repositioned and stabilized with screw with the distal segment. In three cases vertical sub-sigmoid osteotomy was carried out to retrieve the condylar head. After assembling the osteotomised segment and condylar segment, it was repositioned and stabilised in predetermined position. Post operatively the patients were on inter maxillary fixation for a week followed by active physiotherapy. RESULT: The follow up period was between 2-11 years. In nine cases occlusion and mandibular function was good. There was no resorption of the condylar head. One case had complete resorption of the condylar head. Other case had fracture of the bone plate. CONCLUSION: Extracorporeal fixation is an effective method for management of displaced and dislocated condylar fracture.
