Objectives:To compare the clinical and radiological outcomes after closed reduction (CR) and open reduction and internal fixation(ORIF) in the management of subcondylar fractures.
Materials and Methods:Forty-eight patients presenting with subcondylar fracture between January 2010 and March 2013 were evaluated retrospec-tively. Fifteen patients were treated with CR and 33 patients with ORIF. The clinical and radiologic parameters were evaluated during follow-up (mean, 7.06 months; range, 3 to 36 months).
Results: In the CR group, no patients had any problems with regard to the clinical parameters. The average period of maxillomandibular fiation (MMF) was 5.47 days. The preoperative average tangential angulation of the fractured fragment was 3.67º, and loss of ramus height was 2.44 mm. In the ORIF group, no clinical problems were observed, and the average period of MMF was 6.33 days. The preoperative average tangential angulation of the sub-condylar fragment was 8.66º, and loss of ramus height was 3.61 mm.
Conclusion: CR provided satisfactory clinical results, though ORIF provided more accurate reduction of the fractured fragment. So there is no dis-tinct displacement of fractured fragment, CR should be selected than ORIF because of no need for surgery.
