The function of the Eustachian tube was assessed in 50 patients suffering from sudden hearing loss, using the pressure chamber impedance method. We investigated the existence of a relationship between sudden hearing loss and the occurrence of a patulous tube. We could not observe more patulous tubes in patients with sudden hearing loss compared to a control group with healthy ears. We registered the parameters "tissue resistance pressure" and "tubal opening pressure", both characterising the passive qualities of the Eustachian tube. There was no indication of a facilitated passive tubal opening nor a tendency to a patulous tube among our patients. Statistical evaluation of these parameters showed no significantly different tubal function on comparing the right and the left ear, as well as the ear affected by sudden hearing loss and the healthy ear. We conclude that there is no relationship between sudden hearing loss and patulous tube.
采用压力室阻抗法对50例突发性听力损失患者的咽鼓管功能进行了评估。我们研究了突发性听力损失与咽鼓管异常开放之间是否存在关联。与健康耳朵的对照组相比，我们在突发性听力损失患者中未观察到更多的咽鼓管异常开放情况。我们记录了“组织阻力压力”和“咽鼓管开放压力”这两个参数，它们均表征咽鼓管的被动特性。在我们的患者中，没有迹象表明咽鼓管被动开放容易或有咽鼓管异常开放的倾向。对这些参数的统计评估表明，比较左右耳以及受突发性听力损失影响的耳朵和健康耳朵时，咽鼓管功能没有显著差异。我们得出结论，突发性听力损失与咽鼓管异常开放之间没有关联。
