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.
