应用ＫＮＹ型咽鼓管通气功能检测仪检测１１０名现役飞行人员的咽鼓管开放压值（ＥＴＯＰＶ）及其波形（ＷＳ），并进行飞行试验（８０名）和低压舱试验（３０名），研究ＥＴＯＰＶ的大小及其ＷＳ与耳气压机能（ＯＢＦ）的关系。实验结果提示：（１）ＥＴＯＰＶ及其ＷＳ与ＯＢＦ之间有密切关系，ＥＴＯＰＶ大的人耳气压调节机能差，容易发生耳气压伤（ＥＢＴ），ＥＴＯＰＶ小的人耳气压调节机能好，很少发生ＥＢＴ。（２）Ｂ型波是咽鼓管通畅程度不良的波形，较Ａ型波更易发生ＥＢＴ。
The Eustachian tube open pressure (ETOPV) and its waveform (WS) of 110 active pilots were tested by KNY type Eustachian tube ventilation test, and 80 flight tests and 30 low pressure cabin tests were conducted. Study ETOPV size and its WS and ear pressure function (OBF) relationship. The results suggest that: (1) There is a close relationship between ETOPV and its WS and OBF, and ETOPV with large ETOPV is poor in air-pressure regulation and is prone to ear-stroke pressure injury (EBT) EBT occurs. (2) Type B wave is a waveform of poor eustachian tube patency, more prone to EBT than Type A wave.
