摘要
咽鼓管通气障碍产生中耳负压是鼓膜内陷囊袋的发生机制,内陷囊袋如果不断加深,就可能导致后天原发性胆脂瘤。为什么临床上常看到松弛部胆脂瘤患者的紧张部和中鼓室是正常的,耳内镜技术的发展给出了清晰的答案:大多数人的上鼓室通气完全依赖鼓峡,在咽鼓管功能恢复后仍长期封闭,上鼓室就形成了"选择性低通气",由此可能出现最常见的后天原发性胆脂瘤。本文就中耳通气影响因素和上鼓室选择性通气障碍的研究进展作一综述。
Disfunction of Eustachian tube will cause negative pressure of middle ear, which may result in tympanic membrane retraction pocket. Severe pocket can consequently cause cholesteatoma. In clinical practice it is not uncommon to find a cholesteatoma limited to epitympanum, with an otherwise normal pars tensa and mesotympanum. This review explains the theory of "selective epitympanic dysventilation syndrome" developed by endoscopic technique. In the majority of the patients, the only ventilation pathway to the epitympanum is through the tympanic isthmus. Even if Eustachian tube function has recovered, an isthmus blockage with selective epitympanic dysventilation may lead to common attic cholesteatoma.
