Abstract
|
|
|
This study evaluated the results of surgical and conservative treatment of managing simulated unilateral dislocated fractured mandibular condyles. Group A left the fractured condyle in its dislocated position outside the glenoid fossa. Group B
consisted
of surgical treatment by completely detaching the condyle, then replacing it as free graft and its subsequent fixation with interosseous wiring. Immediate postoperative mandibular function was performed in both groups. In both groups, we
performed
simulated retrodiscal injury and discal displacement by incision.
Clinical, morphologic, functional, radiologic, and histologic examinations were conducted on all animals.
@ES We got the following results.
@EN 1. There were no functional and morphological deformities in both groups.
The radiographic examination showed the good union of fractured line and condylar remodeling at 3 months in both groups.
In all experimental period, no inflammatory reaction was observed. In both groups, good condylar remodeling change was observed. The chondroid tissues apperared between the hypertrophic zone and subchondral bone area. None of the condyles were
lost
as
result of necrosis in group B.
