A Case of Cholesterol Granuloma of the Frontal and Ethmoid Sinus / 대한이비인후과학회지

ABSTRACT

Cholesterol granuloma of the paranasal sinus is a rare condition. It is rarely diagnosed preoperatively, as correct diagnosis depends on its characteristic histological picture. It is currently thought that impaired drainage, hemorrhage and inadequate ventilation play significant roles in its pathogenesis. We have experienced a case of cholesterol granuloma that had developed in the frontal and the ethmoid sinuses, which was managed successfully by transnasal endoscopic marsupialization. We report this case with a literature review.
