A CASE REPORT ON AN OLD FRACTURE-DISLOCATED MANDIBULAR CONDYLAR PROCESS CORRECTED BY CONDYLECTOMY

This is a case report on the old fracture- dislocated mandibular condylar process corrected by condylectomy. Fracture. dislocation of the mandibular condylar process was caused by car accident. This case report could be summerized as follows. 1. Fracture of the condylar process of the mandible resulted in the limitation of the mandibular movement, difficulty of the mastication and the malocclusion accompaning the pain. 2. Reduction of the mandibular condylar process was difficult because of the atrophy of the joint capsule and the significant scarring and fibrous filling of the vacated joint space. 3. In the patient with old fracture-dislocation of the mandibular condylar pro cess, condylectomy was necessavy. 4. In the patient with unilateral condylectomy, occlusal condition returned to normal, but slight mandibular deviation toward operation site was noted in maximum mouth opening.
