Abstract
Osteochondroma is one of the most common benign tumors of the axial skeleton, but is rarely found in the facial bones. Osteochondroma shows an irregular radiopaque lesion and chondromatic area surrounded by osteoma. It may appear different findings as calcification levels. When it develops in the long bone, it has a marked tendency in the ages from 10 to 20 years and ceases with the end of pubertal growth. However, when it develops in the condyle, it is prevalent in the third decades (average 39.2 years) and continues to develop. Lesions developed in the long bone have a predilection for men (M:F = 2:1), but for women in the mandible. Osteochondroma is differentiated from chondroma, osteochondromatosis and osteoma. Mandibular condyle osteochondroma presents asymptomatic facial swelling, rarely posterior openbite, pain during mouth opening and internal derangement of the temporomandibular joint disc due to condylar lengthening and condylar hyperplasia. The first choice of treatment of the massive osteochondroma is the surgical removal. We report osteochondroma of the mandibular condyle showing good result to treat the lesion.
