Purpose: The purpose of this study was to compare the functions of the condyle and complications after fixation of a subcondylar fracture of the mandible with two noncompression miniplates and a single non-compression miniplate. Materials and Methods : A total of 30 patients who required open reduction of a subcondylar fracture of mandible were selected for the study. The patients were randomly divided into two groups of 15 each. Group I comprised of patients treated with a single miniplate and Group II were treated with two noncompression miniplates. The patients were assessed for malocclusion, lateral deviation on opening, infection, plate removal, facial nerve function, the time taken in the surgery, and cost of implants used, in both the groups. All the parameters were compared statistically using the chi square test. Results: Out of 30 patients, inadequate reduction was noticed in one patient in Group I. Screw loosening occurred in two cases; both the cases were stabilized with a single miniplate. Screw loosening was always associated with chronic infection. In these cases, hardware removal was performed. Plate bending was observed in one case that was stabilized with a single miniplate. Malocclusion and lateral deviation occurred in this case. When two miniplate were used, no plate bending or screw loosening was observed. Malocclusion was observed in Group II. Conclusion: Two plates for subcondylar fractures represent the best solution to obtain stable osteosynthesis in comparison to a single miniplate.
