title: Primary osteoma of the sphenoid sinus.
abstract: Osteomas of the nose and paranasal sinuses are rather common benign tumors arising in the head and neck area. The sphenoid sinus is involved in various inflammatory and neoplastic conditions; however, an osteoma arising from the sphenoid sinus proper has not been reported in the available literature. This paper reviews, in detail, osteomas of the paranasal sinuses and their incidence, and a case of a sphenoid sinus osteoma is presented with radiological and pathological findings.
