摘要
目的分析鼓膜穿孔的慢性中耳炎患者咽鼓管功能和咽鼓管功能障碍的发生率。方法以正-负压平衡法结合Valsalva测试,检测42例(46耳)外伤性鼓膜穿孔和225例(248耳)慢性中耳炎患者的咽鼓管功能。结果外伤性鼓膜穿孔患者咽鼓管主动和被动开放功能均优于慢性中耳炎患者。前者咽鼓管功能障碍的发生率为2.17%(1/46),而后者高达76.21%(189/248)。结论在慢性中耳炎患者群体中,负压状态下咽鼓管开放压最先受到损伤。咽鼓管功能障碍的高发,主要表现为腭帆张肌功能不良为主的主动开放功能障碍。
Objectives To assess eustachian tube function and the incidence of eustachian tube dysfunction in patients with chronic otitis media and in those with tympanic membrane perforation. Methods Positive-negative pressure balance was used in combination with Valsalva＇s maneuver to assess eustachian tube function in 42 patients（46 ears） with traumatic tympanic membrane perforation and 225 patients（248 ears） with chronic otitis media. Results Voluntary and passive eustachian tube opening in patients with traumatic tympanic membrane perforation were superior over those with chronic otitis media. The rate of eustachian tube dysfunction was 2.17%（1/46） in the former group and 76.21%（189/248） in the latter.Conclusions In patients with chronic otitis media, eustachian tube opening under negative pressure is the first to be affected, with an increased incidence of eustachian tube dysfunction, mainly due to poor tensor veli palate functions that lead to impaired voluntary tube opening.
