A group of 12 children with acquired cholesteatoma had the ventilatory function of the Eustachian tube assessed by the inflation-deflation technique. All had varying degrees of functional rather than mechanical obstruction of the Eustachian tube. In these children, the pathogenesis of acquired cholesteatoma appeared to be the result of the following sequence of events: functional Eustachian tube obstruction, high negative middle ear pressure, atelectasis of the tympanic membrane-middle ear, a retraction pocket in either the posterosuperior or attic portion of the tympanic membrane, and adhesive otitis media. Tympanoplasty in these children was not successful. It is suggested that when the middle ear-mastoidectomy cavity is allowed to remain open, then the bony portion of the Eustachian tube should be surgically closed to prevent postoperative reflux of nasopharyngeal secretions.
一组12名患有后天性胆脂瘤的儿童通过充放气技术评估了咽鼓管的通气功能。所有儿童均存在不同程度的咽鼓管功能性而非机械性阻塞。在这些儿童中，后天性胆脂瘤的发病机制似乎是由以下一系列事件导致的：咽鼓管功能性阻塞、中耳负压增高、鼓膜 - 中耳萎陷、鼓膜后上或鼓室上隐窝处的内陷袋以及粘连性中耳炎。这些儿童的鼓室成形术未成功。建议当允许中耳 - 乳突切除腔保持开放时，应通过手术封闭咽鼓管的骨性部分，以防止术后鼻咽部分泌物反流。
