Abstract

It is common to find cholesterol granuloma in the mastoid antrum and air cells of the temporal bone, but it is very rare in paranasal sinuses, especially in ethmoid sinus. Diagnosis is rarely suspected preoperatively, and depends on the finding of characteristic histological picture. It is currently thought that disturbed ventilation, impaired drainage and hemorrhage play a significant role in the formation of cholesterol granuloma. Five cases with cholesterol granuloma of the paranasal sinus, one that was limited to ethmoid sinus and the others of the maxillary sinuses, are presented and discussed.
