title: Osteochondroma of the glenoid fossa--report of two cases with sudden onset of symptoms.
abstract: Osteochondroma of the temporomandibular joint is a rare condition that most frequently affects the mandibular condyle. Fixed osteochondroma originating from the glenoid fossa is extremely rare and a literature search identified only two reported cases. The cases of two additional patients in whom osteochondroma developed in the posterior part of the glenoid fossa leading to the sudden onset of chin deviation and malocclusion are reported herein. We conclude that osteochondroma of the glenoid fossa is a slow growing benign tumour with typical clinical and radiological features. It requires surgical treatment, comprising resection of the tumour. Recurrence appears unlikely.
