magnetic resonance examination of tmjs following open reduction and internal fixation using rhombus and two miniplates in management of unilateral subcondylar fracture
The objective of this study was to present a prospective study to investigate TMJ following open of unilateral subcondylar fracture using MRI. 30 adult male patients with recent history of unilateral mandibular subcondylar fractures were included. Three groups based on the method management of the subcondylar fracture mandibular fracture. Group 1 comprised patients who had unilateral condylar fractures treated by open reduction and internal fixation of subcondylar fracture using 3D rhombus plate (Orthomed) Group 2 patients were treated by open reduction and internal fixation of subcondylar fracture using 2 mini plates. Group 3 Control group were treated patients had a unilateral condylar fracture treated by closed reduction. Magnetic resonance imaging was performed on the patients within 10 days from the primary injury. The same clinical examination, radiographic and magnetic resonance imaging were performed six months later. The result of this study demonstrate that,there was no statistically significant differences observed between the three treatment groups for parameters like age, gender, type and side of the fracture, mechanism of injury and incidence of associated injuries, post-operative occlusion and need for IMF There was a no statistically significant difference between the MRI findings in all groups.
