Abstract
We describe our experience with a case of osteochondroma of the left mandibular condyle. A 38-yearoldman presented with a 16-year history of slowly developing facial asymmetry and occlusal dysfunction. Preoperative computed tomography (CT) and magnetic resonance imaging (MRI) revealed a well-definedtumor arising from the left mandibular condyle. A huge tumor was located in the infratemporal fossa. Osteochondroma of the mandibular condyle was diagnosed. Preoperative analysis of a gnathostatic model andpaper surgery indicated that facial asymmetry and occlusal dysfunction would be improved by immediate reconstructionof the jaw with an artificial mandibular condyle after resection of the tumor. The lesion was surgicallytreated via a temporal-preauricular approach, Al-Kayt-Bramley's method, by resecting the zygomatic arch temporarily.The tumor was removed by means of condylectomy, and the defect was repaired with artifical material.The postoperative course was uneventful. The use of an artificial mandibular condyle with an adjustable connectorcontributed to the postoperative TMJ function and occlusal restoration.
