Abstract

Osteochondroma is the most common benign tumor of the axial skeleton, though it is rarely found in the oral and maxillofacial regions. Reported is a case of osteochondroma affecting the mandibular condyle of a 22-year-old Japanese woman. The patient visited the hospital with the chief complaint of facial asymmetry. She had pain with clicking on her right temporomandibular joint (TMJ), resulting in trismus and facial asymmetry with a chin deviation to the left side. Her maximum jaw opening was 34 mm, with moderate left TMJ tenderness. There was Class I occlusion without open bite. Panoramic radiography and computed tomography (CT) revealed an enlarged right mandibular condylar head. Magnetic resonance imaging (MRI) also showed an enlarged condyle with hyperintense bone marrow on a T2-weighted image. Condylectomy and condyloplasty were performed. Surgical specimen of the lesion revealed osteochondroma of the mandibular condyle head. Two months after the initial surgery, facial asymmetry was surgically corrected by Le Fort I osteotomy and chin reduction. The patient was discharged from the hospital with no subjective complaints. At the time of this report, the patient had been followed up for seven months, and there had been no evidence of recurrence.
