Cholesterol granulomata of the middle ear occasionally accompany chronic middle-ear diseases with diminished ventilation. 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.
中耳胆固醇肉芽肿偶尔会伴随通气功能减退的慢性中耳疾病出现。在鼻窦，尤其是额窦中，胆固醇肉芽肿在文献中偶尔也有提及。通气紊乱和引流障碍是胆固醇肉芽肿发病的决定性致病因素。关于胆固醇的来源以及出血在胆固醇肉芽肿形成过程中的重要性，目前观点仍存在分歧。本文报告并讨论了两例额窦胆固醇肉芽肿患者。
