Detailed aerodynamic patterns for various disorders of the Eustachian tube function were reported. Simultaneous recording of the pressure in the ear canal and the pharyngeal cavity during Valsalva's maneuver and deglutition permitted an objective evaluation of different tubal dysfunctions. The patient with occluded tube showed either disturbance of the air flowing into the tube or outflowing from the tympanum to the pharynx. Depending on the degree of patency, the patulous tube showed either a synchronous change of the tympanal pressure with that of the pharyngeal cavity or an early and sudden drop of the tympanal pressure without deglutition. Through this rather simple aerodynamic technique, evaluation of different tubal dysfunction is possible.
报告了咽鼓管功能各种紊乱的详细空气动力学模式。在瓦尔萨尔瓦动作和吞咽过程中同时记录耳道和咽腔的压力，从而能够对不同的咽鼓管功能障碍进行客观评估。咽鼓管阻塞的患者表现为空气流入咽鼓管或从鼓膜流出至咽部受到干扰。根据通畅程度，咽鼓管异常开放的患者表现为鼓膜压力与咽腔压力同步变化，或在无吞咽情况下鼓膜压力早期突然下降。通过这种相当简单的空气动力学技术，可以评估不同的咽鼓管功能障碍。
