Eustachian tube (ET) function was measured before and after surgery in patients with acquired cholesteatoma. The cholesteatoma group and a group of patients without cholesteatoma but with dry tympanic membrane perforations (TM-Perf) were compared in this respect. ET function was measured by the air pressure equalization technique; if necessary, a transmyringeal tube was inserted to establish direct communication between the external ear canal and the middle ear cleft. No difference in ET function was found before and after surgery in the cholesteatoma group. The ET testing results in the cholesteatoma group were inferior to those in the group with TM-Perf. These findings are discussed in relation to proper surgical procedure in ears with cholesteatoma.
对获得性胆脂瘤患者在手术前后测量了咽鼓管（ET）功能。在这方面，对胆脂瘤组和一组无胆脂瘤但有干性鼓膜穿孔（TM-Perf）的患者进行了比较。通过气压平衡技术测量ET功能；如有必要，插入经鼓膜管以建立外耳道与中耳腔之间的直接连通。胆脂瘤组手术前后的ET功能未发现差异。胆脂瘤组的ET测试结果低于TM-Perf组。结合胆脂瘤耳的适当手术操作对这些发现进行了讨论。
