The Osteochondroma of the Mandibular Condyle: Report of a Case

하악과두에 발생된 골연골종의 증례보고

The osteochondroma, also known as osteocartilagenous exostosis, is one of the most common benign tumors of the axial skeleton, but is rarely found in the facial bones. When present, the tumor is most often reported to affect the mandibular coronoid process. Osteochondroma of the mandibular condyle is extremely rare and may cause signs and symptoms like those seen in patients with temporomandibular joint dysfunction. Sometimes, differentiation between osteochondroma and condylar hyperplasia is not possible on histologic grounds alone, but the radiographic and intraoperative findings together are usually sufficient to establish a definite diagnosis. This report reviews the literature concerning osteochondroma, especially of the maxillofacial region, and describes a case of osteochondroma of the condyle.
