In order to determine the effect of muscular contraction upon the opening processes of the eustachian tube, cineradiography of four monkeys' tubes during stimulation of the tensor and levator veli palatini muscles was carried out. Levator stimulation produced no opening of the tube except a dilation of the pharyngeal orifice. On the other hand, tensor stimulation produced a consistent opening of the tube by outward displacement of the tubal wall along its entire cartilaginous part. A marked time lag in the movement of the tube between its proximal (isthmic) and distal (pharyngeal) parts was regarded to be important in the clearance function of the tube.
为了确定肌肉收缩对咽鼓管开放过程的影响，在对腭帆张肌和腭帆提肌进行刺激时，对四只猴子的咽鼓管进行了X线电影摄影。刺激腭帆提肌时，除了咽口扩张外，咽鼓管未开放。另一方面，刺激腭帆张肌时，咽鼓管管壁沿其整个软骨部分向外移位，从而使咽鼓管持续开放。咽鼓管近端（峡部）和远端（咽部）之间的运动存在明显的时间滞后，这被认为对咽鼓管的清除功能很重要。
