The effects of age on Eustachian tube efficiency were examined using a tympanometric swallow procedure. Ten aged males and 10 young controls served as subjects. Tympanograms were examined for middle ear pressure and amplitude after a swallow maneuver and manipulation of external auditory meatus pressure. Statistical analysis of pressure peak findings revealed a significant interaction effect (age X tympanometric condition), which reflected less extreme pressure shifts obtained from geriatric subjects. Lack of shift and shift in the opposite direction from expectation among the geriatric subjects were both observed. The authors suggested that further exploration of possible hypofunction of the aged Eustachian tube relative to that of the young controls is warranted.
采用鼓室导抗吞咽法研究年龄对咽鼓管功能的影响。选取10名老年男性和10名年轻对照者作为研究对象。在吞咽动作及外耳道压力操作后，检查鼓室导抗图的中耳压力和振幅。对压力峰值结果的统计分析显示存在显著的交互作用（年龄×鼓室导抗测量条件），这反映出老年受试者的压力变化幅度较小。老年受试者中既观察到压力无变化的情况，也观察到与预期相反方向的压力变化。作者认为有必要进一步探究老年咽鼓管相对于年轻对照者可能存在的功能减退情况。
