A giant osteoma of the mandible.

An osteoma is a benign, slow growing osteogenic tumor characterized by proliferation of either compact or cancellous bone. It can be central, peripheral or extraskeletal. Clinically osteomas are usually asymptomatic. These lesions often go undetected unless incidentally found on radiographic survey or until they have extended to such an extent that they cause facial asymmetry or functional impairment. The most common site of osteoma to develop in maxillofacial region is skull. Giant osteomas in mandible are rare. We present and discuss a case of giant osteoma of right mandible which was surgically excised.
