How To Open Eustachian Tube [exclusive]

Three primary muscles are responsible for dilating the tube: the tensor veli palatini, the levator veli palatini, and the salpingopharyngeus. The tensor veli palatini is the primary dilator. When these muscles contract, they pull on the cartilaginous walls of the tube, prying it open against the elastic forces that keep it closed. This action usually occurs involuntarily during swallowing or yawning, but it can also be facilitated through specific voluntary maneuvers.
