目的:探讨咽鼓管-鼓室气流动态图法(TTAG法)对健康人群咽鼓管功能进行不同亚群分类的临床实用性。方法:对66例(132耳)健康人使用TTAG法采用Valsalva动作检测咽鼓管被动通气功能,并对结果和图形进行分析。结果:TTAG法检测阳性率为93.3%(124/132)。根据曲线特点和吞咽次数将阳性耳分为Ⅰ型77耳,Ⅱ型47耳,两型ET开放时鼻咽腔压力均值比较差异无统计学意义(P>0.05),外耳道压力均值差异有统计学意义(P<0.01)。结论:TTAG法对判定健康人群中咽鼓管功能不同亚群状态有一定临床应用价值。
Objective: To investigate the clinical utility of EEG - TEG method in different subgroups of eustachian tube function in healthy subjects. Methods: 66 cases (132 ears) of healthy people using Tals method Valsalva action detection of Eustachian tube passive ventilation function, and the results and graphics were analyzed. Results: The positive rate of TTAG was 93.3% (124/132). According to the characteristics of the curve and the number of swallowing, the positive ear was divided into type Ⅰ 77 ears and type Ⅱ 47 ears. There was no significant difference in mean nasopharyngeal pressure between two types of ET (P> 0.05) Significance (P <0.01). Conclusion: TTAG has some clinical value for judging the status of different subgroups of Eustachian tube function in healthy people.
