Tube Troubles. The Eustachian tube is a small passageway from your inner ear to the back of your nose, and plays an important part in the hearing process. Every time you swallow, yawn, or blow your nose, the Eustachian tube opens and allows air to pass from the middle of your ear to the back of your nose. This process equalizes the pressure in our ears, and prevents the eardrum from bulging in or out too much.
