[Osteoma of the mid-face area--a rare site]

Osteomas are benign, symptomless, slowly growing tumors that are usually found incidentally. The most frequent site of origin is a paranasal sinus. We report a 17 year old man with an osteoma of the middle face. The history, clinical findings and surgical procedure are described. Aetiological factors and possible complications of paranasal osteomas are discussed.
