Large exostosis of the mandibular coronoid process. Report of a case.

The clinical experience of a patient with a large exostosis who had a chief complaint of difficulty in opening the mouth is reported. Radiographic examinations, especially tomography and a CT scan, were useful in the diagnosis. Surgical removal is the treatment of choice. The lesion is usually approached by a combination of intraoral and buccal routes; we also employed such an approach in this particular case.
