Osteochondroma and osteoma of the mandibular condyles : Report of 2 cases and literature review

Osteochondroma and osteoma are benign bone tumors occurred rarely on the condyle of the mandible. Although they grow very slowly and have no specific malignant signs or symptoms in ealy stage, they can cause severe dentofacial deformities and/or functional disturbances as facial asymmetry, malocclusion, posterior open-bite and temporomandibular joint dysfunctions when they are increased markedly on the condylar head of the mandible. This is a report of 2 cases of osteochondroma and osteoma which occurred unilaterally in the condylar head of the mandible and resulted in severe facial asymmetry, malocclusion and functional disturbances due to large expansion of tumor masses. We obtained successful functional and esthetic results by simple surgical excision of tumor mass, intermaxillary fixation for short duration and active physical therapy.
