分泌性中耳炎C型鼓室导抗图咽鼓管功能的检测

The evaluation of eustachian tube function in patients suffered from SOM with C type curve

目的 :探讨分泌性中耳炎 ( SOM)、鼓室导抗图为 C型患者的咽鼓管功能。方法 :检测捏鼻吞咽法( Toynbee法 )和捏鼻鼓气法 ( Valsalva法 )后的鼓室导抗图 ,峰压点的移动进行量化处理 ,评价 3 0例 SOM( 4 2耳 )的咽鼓管功能 ,并与正常对照组相比较。结果 :咽鼓管功能障碍者占 5 2 .3 8% ,与正常对照组相比有显著性差异 ( P<0 .0 5 )。结论 :咽鼓管功能障碍是 SOM的病因之一 。

Objective:To explore eustachian tube (ET) function in patients suffered from SOM with C type curve.Method:To test the tympanogram following toynbee test and valsalva manoeuvre respectively.The shift of peak point was quantified and the results were compared with normal subjects.Result:ET dysfunction was found in 52.38 % of the patients,it was observed in 30% of the normal subjects (P< 0.05 ).Conclusion:ET dysfunction is one of the causes of SOM with C type curve,but not the only cause.
