An illustration used to instruct patients on the muscles that control the shape of the Eustachian tubes, levator veli palatini and tensor veli palatini. The Eustachian tubes’ ability to open is critical in equalizing air pressure in the middle ears. The eardrum or tympanic membrane does not allow air from the auditory canal into the middle ear, which in occasions of air pressure changes can be painful. With the help of levator veli palatini and tensor veli palatini the Eustachian tubes allow air to the middle ears from the throat when the mouth is opened.
