Comparative evaluation of post treatment CT scan and clinical parameters in open reduction and closed reduction treatment of condylar fractures

Abstract

Background: Mandibular fracture is the second most common fracture of facial bone, next to nasal bone. Twenty-five to forty percent of mandibular fractures involve the condyle. In the literature, there exists no consensus “gold standard” treatment for mandibular condylar fractures, and there is a continuing debate on whether condylar fractures should undergo closed or open reduction. Materials and Method: Twenty patients who had undergone open reduction and closed reduction treatment were included in the study. Clinically maximal interincisal opening, laterotrusive and protrusive movements, pain on mouth opening, malocclusion, chin deviation on mouth opening, facial nerve palsy, hematoma, infected implant, and bite force were evaluated after a minimum of 3 months postoperatively. Also, a postoperative CT is done to evaluate the anatomical position of fragment. Results: On evaluation of clinical parameters, both groups had comparable results. However, none of the patients in open reduction group had deviation of mandible from midline on mouth opening. Also, better anatomical repositioning is obtained in open reduction group. Conclusion: The results of this study suggest that the open reduction method is a better alternative to closed reduction in treatment of mandibular condylar fractures.
