Inter maxillary fixation versus open reduction for the treatment of mandibular condyle fractures: A comparative evaluation

Abstract

Background: The treatment for fractured mandibular condyles aims at restoring the masticatory ability, occlusion, symmetry, and function as the bit were before the trauma. The treatment of the mandibular condylar fracture can be done based on the two protocols. Aims: The present clinical trial was conducted to collate aftertreatment upshot of closed treatment and open surgical treatment for mandibular condyle fractures. Materials and Methods: Forty-two patients were divided into two groups (n = 12) which were treated with either the closed reduction using intermaxillary fixation or open reduction and internal fixation. The following clinical parameters were assessed at 1st and 3rd day and at 1, 3, and 6 weeks: lateral excursion and protrusion, occlusion; interincisal opening, mandibular ramus height, deviation/deflection during jaw opening, and pain assessment using visual analog score. The collected data were subjected to statistical evaluation. Results: Interincisal opening was found to be 8.125 ± 0.3467 mm and 6.016 ± 0.1528 mm, respectively, for Group I and Group II which was statistically significant (P < 0.00001). At the 3 months and 6th week postoperatively, it was increased in the surgical groups to 17.433 ± 0.3822 mm and 19.175 ± 0.3696 mm, respectively. Conclusion: The present trial suggests surgical open reduction and internal fixation treatment of the mandibular condylar fracture is better than the nonsurgical closed reduction in terms of interincisal opening, lateral excursion, and protrusive mandibular movement range.
