Mandibular osteoma as a cause of ankylosis and progressive trismus.

Osteomas are benign tumours of bone tissue restricted to the craniofacial skeleton. The aim of this article is to present and discuss the demographic and clinical aspects and the management of craniomaxillofacial osteomas. When the patient was submitted from primary care to our hospital, he was 68 years old, and he had ankylosis of the temporomandibular joint for the previos 4 years. A CT scan was performed, finding a giant mandibular osteoma. Conservative treatment and radiological follow-up were carried out with clinical stability. Osteomas more often are seen in the paranasal sinuses and in young adults, with no differences in gender. Most are asymptomatic, but they can cause local problems. For its diagnosis, CT is usually performed. Treatment options are conservative management and follow-up or surgery. Although rarely, they can recur. Mandibular peripheral osteoma is a rare entity. Depending on the symptoms, a conservative or surgical treatment can be chosen. A clinical and radiological follow-up is necessary to detect possible recurrences or enlargement.
