Osteoma of mandible: A case report.

Osteoma is a leisurely growing benign tumour involving bone consisting of well differentiated compact or cancellous bone that increases in size by continuous growth. It can be of a central, peripheral or extraskeletal type. The peripheral type emerges from periosteum. Solitary osteoma can be classified as peripheral (parosteal, periosteal or exophytic) when arising from the periosteum, central (endosteal) when arising from the endosteum or extraskeltal (so- called osseous choristoma) when arising in soft tissue. This article describes a case of 27 years old female who presented with painless swelling in the left body mandible and which was slowly growing and resulted in facial disfigurement. Ostectomy of the lesion was done under general anaesthesia. Postoperatively there was no complication and there was no facial asymmetry. After one year of follow up no recurrence was noted and patient has been kept on regular follow up.
