Aims and Objectives: The aim of the present study was to compare closed treatment with open reduction internal fixation (ORIF) for subcondylar and condylar neck fractures. Materials and Methods: This randomized prospective study was conducted on thirty patients who visited the Department of Oral and Maxillofacial Surgery, Government Dental College, Srinagar, with condylar fractures. All fractures were displaced; either angulated between 10° and 45° and the ascending ramus was shortened by >2 mm to <15 mm. Patients were divided into two groups after satisfying the inclusion and exclusion criteria – Group I (closed treatment) and Group II (open reduction) (15 implants in each group). In Group I, patients were treated by mandibulo-maxillary fixation using arch bar and elastics for 4 weeks, and in Group II, patients were treated by ORIF using two 1.5-mm miniplates. Follow-up was done at 1 month, 3 months, and 6 months. Our postoperative evaluation included five parameters – maximal interincisal opening, protrusion, lateral excursion on fractured and nonfractured sides, anatomical reduction, and pain and malocclusion. Nonparametric data were compared for statistical significance with Chi square test and parametric data with an independent sample's t-test (P < 0.05). Results: Correct anatomical position of the fragments was achieved significantly more accurately in the operative group in contrast to the closed treatment group. Regarding mouth opening/lateral excursion on fractured and nonfractured sides/protrusion, significant (P < 0.05) differences were observed between both groups (open 39.73/7.50/8.17/7.87 mm vs. closed 36.87/6.07/7.23/7.13 mm). Pain also revealed significant (P = 0.025) difference with less pain in the operative treatment group. Conclusion: Both treatment options for condylar fractures of the mandible yielded acceptable results. However, operative treatment was superior in all objective and subjective functional parameters except occlusion.
