Contrast roentgenography and cineroentgenography were carried out on nine patients with perforated eardrums to reveal the opening process of the Eustachian tube and its pumping-like clearance function in human beings. The results were as follows: (1) the tubal lumen opens along the cartilaginous part of the tube owing to the outward displacement of its lateral wall; (2) the pumping function of the tube consists in two phases: accumulation of the fluid in the tube by tensor contraction and discharge of the fluid by tensor relaxation.
对9例鼓膜穿孔患者进行了对比X线造影和电影X线造影，以揭示人类咽鼓管的开放过程及其类似泵的清除功能。结果如下：(1) 由于咽鼓管侧壁向外移位，管腔沿软骨部开放；(2) 咽鼓管的泵功能包括两个阶段：通过腭帆张肌收缩使液体在管内积聚，以及通过腭帆张肌松弛使液体排出。
