对五十六例鼓室乳突手术后的患者进行检查，以确定乳突通气的恢复情况以及各种术前和术中因素，如咽鼓管（ET）功能、术中如何处理乳突粘膜以及是否在中耳放置了大硅橡胶片或使用了通气管。57例病例中有27例（47%）在术后12个月内通过计算机断层扫描证实乳突通气恢复。在所检查的因素中，发现保留上鼓室粘膜对乳突通气的恢复最为重要。用大的硅橡胶片覆盖从骨ET和鼓室到上鼓室、窦口或窦的区域，发现在完全切除粘膜和乳突气房后，对恢复乳突通气有一定帮助。术前ET功能、前鼓室切开术和使用通气管不影响恢复。
Fifty-six patients after tympanomastoid surgery were examined to determine recovery of mastoid aeration and various pre- and intraoperative factors such as eustachian tube (ET) function, how the mastoid mucosa had been treated during surgery and whether or not a large silastic sheet had been placed in the middle ear or a ventilation tube used. Mastoid aeration recovery was confirmed by computed tomography in 27 of the 57 cases (47%) within 12 months of surgery. Among the factors examined, preservation of the epitympanic mucosa was found to be most Important in mastoid aeration recovery. Use of a large silastic sheet to cover the area from the bony ET and tympanic cavity to epitympanum, aditus ad antrum or antrum was found to be of some help in recovery mastoid aeration after complete resection of the mucosa and mastoid air cells. Preoperative ET function, anterior tympanotomy and use of a ventilation tube did not influence recovery.
