Description

In order to determine the role of the tensor tympani muscle in Eustachian tube function, pressure change of external and middle ear of 13 cats were measured under 4 experimental conditions. It was revealed that single contraction of the tensor tympani muscle during swallowing elicited no pressure change in the tympanum. Then, acoustic stimulation was used as a measure of consistent contraction of the tensor tympani muscle. Simultaneous contraction of the tensor tympani muscle by sound and that of the tensor veli palatini muscle by electrical stimulation failed to open the tube. As a result it may be concluded that the tensor tympani muscle does not play any role in tubal function.
