Osteochondroma of the mandibular condyle : literature review and report of two cases

Osteochondroma is the most common benign tumor of axial and appendicular skeletons. While this tumor occurs at long bones exclusively, however, the lesion have been reported in many other skeletal site including the scapula, vertebra, ilium and mandible. In the mandible, most of lesions involve the coronoid process and the condylar osteochondroma is very rare. Condylar osteochondroma may manifests varying clinical signs and symptoms which include prognathic deviation of the mandible to the opposite side, malocclusion, cervicofacial pain and limited mouth opening. The majority of surgical treatments have been condylectomy. But recently, simple extirpation of lesion with condylar salvage were reported to maintain functions of mandible and the ramal height postoperatively. We have experienced two cases of condylar osteochondroma treated with simple extirpation of lesion and condylar shaving, and would like to report these with review of literatures.
