comparative analysis of rigid and non rigid fixation in mandibular fractures: a prospective study

ABSTRACT

The aim of this prospective study was to compare the postoperative outcome in 80 mandibular fractures patients, treated by open reduction and internal fixation [ORIF] and intermaxillary fixation [IMF] at Oral and Maxillofacial Surgery Unit, Khyber College of Dentistry, Peshawar from 10th February 2006 to 9th February 2007. The most common age group involved was 21-30 years and the common cause of fractures was road traffic accidents [38.75%], followed by fall [31.25%]. Most common site of fractures was parasymphysis [41.24%] followed by angle [25%]. Patients were divided in two treatment groups, having 40 patients in each group. Rigid internal fixation was assigned as group A and intermaxillary fixation as group B. Data regarding the study was evaluated and reviewed. Two patient groups were not significantly different in relation to postoperative normal occlusion [p=0.45], malocclusion [p=0.45], mAl union [p=0.45], delayed union [p=0.07], non union, infection [p=0.28] and sensory disturbances [p=0.07]. The result was significant in relation to mouth opening [p=0.0001]. This study will help us regarding the measures to be taken in prevention of postoperative complications
