摘要
目的 研究探讨一种简便、灵敏、客观的咽鼓管功能的评价法。方法 利用声导纳仪检测捏鼻鼓气 (Valsalva法 )峰压时峰导纳之变化 ,描记时间 导纳曲线 (T Y) ,评价疑有咽鼓管功能障碍者 10 0例 (130耳 )的咽鼓管功能 ,并与Valsalva、Toynbee及Inflation Deflation试验 (V T ID)相比较。结果 疑有咽鼓管功能障碍者T Y阳性率为 99.4 % ,与V T ID(88.7% )相比有显著性差异 (P <0 .0 1) ;正常对照组采用两种方法检测咽鼓管功能假阳性率也有显著差异 (P <0 .0 5 )。结论 闭口捏鼻鼓气状态下描记的时间 导纳曲线 (T Y) ,可作为评价咽鼓管功能的指标。
Objective To investigate a simple,sensitive and objective method for evaluating the function of eustachian tube. Method To examine the changes of peak admittance at peak pressure by Valsaslva with acoustic impedence admittance measurements machine and record the curve of T-Y to evaluate the function of 100 individuals whose eustachian tube maybe dysfuction.The results were compared with those measured by Valsalva,Toynbee and Inflation-Deflation respectively.Results the positive rates in doubtful eustachian tube dysfunction was 99.4%,which had significant difference compared with V-T-ID(P<0.01); the false positive rates were remarkable differences in normal controlled group examined by two different methods.(P<0.05).Conclusion The T-Y curve associated with Valsalva measurement can be regarded as an index to evaluate the function of eustachian tube.
