Osteochondroma of the mandible causing severe facial asymmetry: A case report

Osteochondroma of the temporomandibular joint: a case report

“…These conditions may also be found in unilateral condylar hyperplasia and other differential diagnoses including osteoma, chondroma, giant cell tumor, myxoma, fibro-osteoma, fibrous dysplasia, fibrosarcoma and chondrosarcoma. In spite of the common clinical features, the definitive diagnosis should always be based on clinical, radiological and histological criteria (2,10,11). Complementary examinations such as panoramic radiography and computed tomography (CT) can be useful to visualize the existing relationships among anatomic structures (13).…”

“…Complementary examinations such as panoramic radiography and computed tomography (CT) can be useful to visualize the existing relationships among anatomic structures (13). Scintigraphy may also be used to detect the presence of intense uptake in the lesion (2,14). In addition, growing bone surrounded by cartilage is expected to be observed under histological evaluation (2,13).…”

“…However, treatment could also be performed without condylectomy (2,3,9), and an association with orthodontic treatment should also be considered.…”

“…It usually occurs in the axial skeleton, especially long bones, such as the distal metaphisis of the femur or the proximal metaphisis of the tibia (1,2). The oral and maxillofacial regions are not common sites of OCs, but the embryonic development of the temporomandibular joint (TMJ), by the endochondral ossification, makes this area the most frequent facial site of this type of tumor (2)(3)(4)(5)(6)(7). Differently from long bones, craniofacial OCs occur at older ages with a slow growth, even at the end of puberty, most frequently affecting women in their second decade of life (1,8,9).…”
