摘要
探讨以粘连性中耳炎为主要表现的中耳胆脂瘤的形成机理及临床意义。方法：通过复习文献并对３例中耳胆脂瘤的临床表现进行分析。结果与结论：①该病属后天原发性胆脂瘤；②咽鼓管通气障碍及前、后鼓峡的阻塞导致内陷袋形成是胆脂瘤发生的直接原因；③颞骨ＣＴ对本病的诊断价值明显大于普通Ｘ线片；④术中如能彻底清除鼓室病变，可一期或分期行鼓室成形术。
To explore the mechanism of cholesteatoma formation in adhesive otitis media withcholesteartoma. Method:Three cases of this kind of disease were reported and literatures were also reviewed. Result and Conclusion:It is a acquired primary cholesteatoma. The eustachian tube and tympanic isthmus blockare the direct cause of these cholesteatoma. CT examination of the temporal bone is more valuable in diagnosisthan that of normal X-ray. If the cholesteatoma lesions can be removed completly, tympanoplasty may be performed in first stage or separate stage.
