There are few cases accompanying it trismus, although, it is observed comparatively a lot that unilateral condylar osteochondroma accompanies the mandibular asymmetry and malocclusion, and a such report with bony-ankylosis is hardly observed.
We report a case of unilateral condylar osteochondroma with bony-ankylosis of temporomandibular joint (TMJ) after arthroplasty. The patient was a 71-year-old woman, complaining of severe trismus and bone-like hard induration at her left TMJ. Radio-graphic examination showed severe deformation of the left mandibular condyle. Condylectomy was performed, and a favorable post-operation course has obtained in the one year after surgery.
