A causal association between eustachian tube (ET) dysfunction and otitis media (OM) has been documented. We present normative data for eustachian tube function (ETF) in an otologically normal population of 107 college-age subjects using two noninvasive methods: nine-step tympanometric testing and sonotubometry. The results show a 78% agreement between the two methods when one test session was performed. The nine-step test showed a 52% repeatability rate on three sequential test sessions while the sonotubometry test showed a 34% repeatability rate. The combined tests showed a 34% agreement for the three sequential tests. The findings reveal that the combination of the two tests identify 96% of normal subjects as having at least some tubal function present. Although both tests provide similar information regarding the presence of tubal opening, the sonotubometry method is more physiologic. Additional information shows that the average category of the nine-step test in a normal population was category 2, the mean duration of tubal dilation was 0.40 seconds, and the mean middle-ear pressure was -12 mm H2O.
咽鼓管（ET）功能障碍与中耳炎（OM）之间的因果关联已有文献记载。我们使用两种非侵入性方法，即九步鼓室图测试和咽鼓管测压法，为107名听力正常的大学生群体提供咽鼓管功能（ETF）的标准数据。结果显示，在进行一次测试时，两种方法的一致性为78%。九步测试在连续三次测试中的可重复性率为52%，而咽鼓管测压法测试的可重复性率为34%。联合测试在连续三次测试中的一致性为34%。研究结果表明，两种测试相结合可识别出96%的正常受试者至少具有一定的咽鼓管功能。虽然两种测试在咽鼓管开放方面提供了相似的信息，但咽鼓管测压法更具生理性。其他信息显示，正常人群中九步测试的平均类别为2类，咽鼓管扩张的平均持续时间为0.40秒，平均中耳压力为-12 mm H2O。
