Abstract

Aim: to evaluate the treatment outcome of fixation of mandibular fractures with eccentric dynamic compression plates. Material and methods: A Retrospective study was conducted in the Department of Dentistry, Anugrah Narayan Magadh Medical College and Hospital, Gaya, Bihar, India from feb 2019 to July 2019. All the 50 patients underwent open reduction with internal fixation of the fractured segments using 2.5 mm, 4 holes with gap Titanium Eccentric Dynamic Compression Plates and 2.5x8 mm titanium screws under general anesthesia or local anesthesia. Fractures of the associated condyle were treated with rigid fixation which was placed for 2-3 weeks. The patients were evaluated preoperatively, intra-operatively and postoperatively for various parameters. Postoperative clinical evaluation was done at the 1st week, 3rd week, 6th week & 3rd month. Evaluation was done for the operative time, ease of fixation of plate (access, reduction and fixation of fractured segments, stability (hardware failure), postoperative occlusion, neurosensory deficits (paraesthesia of the area involved), radiographic evaluation of fracture site at 1 week, 3 weeks, 6 weeks and 3 months and postoperative complications (infection, non-union, mal-union, delayed union). Results: Among the study population, majority of the population were in the age group of 20-30 years. There were 40 (80%) male and 10 (20%) female patients. With road traffic accident (RTA) 45 patients (90%) being the most common aetiology followed by 5 patients with (10%) work related or self-falls. The Fracture distribution consisted of the following, mid- symphysis fracture of mandible 12 (24%) patients, left parasymphysis fracture of mandible 16 (32%) patients, right parasymphysis fracture of mandible 22 (44%) patients, along with associated fracture of the condyle accounting for 26(52%) of patients. The infection rate in our study was found to be 12%. We found the incidence of malocclusion to be 12 % in our study which was due to intra-capsular condylar fracture supposed to be treated with IMF but the patient was non- compliant for the same. Conclusion: All the patients present in the study appreciated early recovery of normal jaw function, primary healing and good union at the fracture site with minimal weight loss due to early functional rehabilitation.
