ANTERIOR MANDIBLE AND CONDYLAR FRACTURE;

A COMPARATIVE EVALUATION OF OPEN AND CLOSED REDUCTION.

Abstract

ABSTRACT… Objectives: To compare the outcome of two treatment protocols (open and closed reduction) in the management of Anterior mandible and condyle fracture in our center. Study Design: Comparative cross sectional study. Place and Duration of Study: Department of Oral & Maxillofacial Surgery, Liaquat University of Medical & Health Sciences, Jamshoro, Hyderabad. This study was conducted from April 2017 to September 2017. Methodology: This study was consisted of total 48 patients which were equally divided into two groups Group-A(Closed Reduction that is Eyelet or Arch Bar) and Group-B(Open Reduction) having anterior mandible were included. For closed reduction technique, maxillomandibular fixation was applied for 4-6 weeks. For open reduction, fracture was fixed with miniplates after achieving the normal occlusion. Post operatively, occlusal disturbances was considered having poor occlusion and patient with maximum intercuspation was considered as good occlusion. Mouth opening more than 25mm was considered as good mouth opening. Results: In group-A 23(95.8%) patients at 3^rd month were found with good occlusion. In group-B, good occlusion was found in 21(87.5%) patients at 3^rd month. In group-A 22(91.7%) subjects at 3^rd month were found with good range of motion and in group-B good range of motion was found in 20(83.3%) subjects at 3^rd month.In group-A, mean deviation was 0.54±0.72 mm at 3^rd month while in group-B, mean deviation was 1.12±1.65 mm at 3^rd month. Conclusion: Open reduction with two correctly positioned plates for the stabilization of anterior mandibular and condylar fractures yielded better function compared to closed reduction.
