In order to determine the role of the tensor tympani muscle in Eustachian tube function, pressure changes in the external and middle ear of 13 cats were measured under four experimental conditions. It was revealed that contraction of the tensor tympani muscle during swallowing did not result in any tympanic pressure rise which might assist in tubal ventilation. Acoustic stimulation was then used to measure consistent contraction of the tensor tympani muscle. Combined contraction of the tensor veli palatini and tensor tympani muscle under the condition of positive tympanic pressure failed to open the tube. It was concluded that the tensor tympani muscle might not play any part in tubal function.
为了确定鼓膜张肌在咽鼓管功能中的作用，在四种实验条件下测量了13只猫的外耳道和中耳的压力变化。结果显示，吞咽过程中鼓膜张肌的收缩并未导致任何可能有助于咽鼓管通气的鼓室压力升高。随后使用声学刺激来测量鼓膜张肌的持续收缩。在鼓室正压条件下，腭帆张肌和鼓膜张肌的联合收缩未能打开咽鼓管。得出的结论是，鼓膜张肌可能在咽鼓管功能中不起任何作用。
