Osteochondroma of mandibular condyle: A clinic-radiographic correlation
A 45-year-old male patient reported to the department with complaint of painless hard slow growing swelling on the right TMJ area and asymmetrical face since two years. He noticed reduced mouth opening and deviation of the jaw while opening and closing the mouth []. There was no history of any trauma or ear infection. The medical history was non-contributory. The clinical examination revealed non-tender bony hard oval swelling on right TMJ measuring around 2 cm × 2 cm [], reduced TMJ movements, facial asymmetry with approximately 8 mm deviation of the midline to the right side, severe malocclusion, unilateral posterior cross bite on the right side, 7 mm negative horizontal overjet and 30 mm mouth opening. No pain but clicking sound was observed on TMJ movements.\nThe Panoramic radiograph [] and open and close right TMJ view [Figure , ] showed a well circumscribed oval-shaped mixed lesion having thin corticated rim. The lesion was attached to the neck of the right condyle. The coronal and axial computed tomograms showed a large hyperdense well defined cartilaginous/bone growth attached to the neck of the right condylar head. The lesion extended from the antero-medial surface of the condyle towards the glenoid fossa and sigmoid notch [Figures -]. The serological investigations were within normal limits.\nBased on history, clinical examination and radiographic findings, the diagnosis of osteochondroma of right TMJ was made with differential diagnosis of osteoma, benign osteoblastoma, chondroma, chondroblastoma. The patient due to phobia has refused surgical intervention and correction of malocclusion. Presently, he is under observation from last six months and no significant changes have been noted.
