在实验室条件下，对8名耳鼻喉正常成年人进行了7 1/2小时的单侧鼻气道阻力变化与同侧中耳压力的关系研究。 尽管与鼻周期相关的单侧鼻阻力的平均变化为0.75 Pa/cm 3/s，但通过连续中耳压力记录判断，与同侧咽鼓管功能的变化不存在相关性（r = 0.06，r2 = 0.00，p = 0.461）。 在受控环境中，健康成人的中耳压力保持非常恒定（平均值= -6.71 +/- 0.52达帕）。 69%的中耳压力等于或高于0达帕，这代表了支持中耳气体净正产生的证据。
The relationship between unilateral changes in nasal airway resistance and the ipsilateral middle ear pressure were investigated in 8 otologically and rhinologically normal adults over the course of 7 1/2 h under laboratory conditions. Despite mean changes in unilateral nasal resistance of 0.75 Pa/cm3/s associated with the nasal cycle, no correlation existed with changes in ipsilateral Eustachian tube function, as judged by serial middle ear pressure recordings (r = 0.06, r2 = 0.00, p = 0.461). Middle ear pressure in healthy adults in a controlled environment remained very constant (mean = -6.71 +/- 0.52 daPa). 69% of middle ear pressures were equal to or above 0 daPa, which represents evidence in favour of a net positive production of middle ear gas.
