In the paranasal sinuses, especially in the frontal sinus, they have occasionally been mentioned in the literature. Disordered ventilation and impaired drainage are decisive pathogenic factors in the causation of cholesterol granuloma. Views remain divided on the source of the cholesterol and on the importance of bleeding in the development of cholesterol granuloma. Two patients with a cholesterol granuloma of the frontal sinus are presented and discussed. Copyright © JLO (1984) Limited 1989 Bütler S.
