title: Cholesterol granuloma of the frontal sinus: a case report.
abstract: Cholesterol granulomas are common in the mastoid antrum and air cells of the temporal bone. In the paranasal sinuses, especially in the frontal sinus, they have occasionally been mentioned in the literature. The pathogenesis is unknown, but the majority of the authors support the concept of airway obstruction in the cells well pneumatised of temporal bone and paranasal sinuses. The authors report a case of cholesterol granuloma of the frontal sinus treated with radical surgical techniques, and they also recommend an endoscopic approach to frontal sinus to restore or enlarge the nose-frontal canal and promote drainage and ventilation of the frontal sinus.
