eustachian tube
Middle ear canal
The eustachian tube is a narrow passage connecting the middle ear to the back of the throat.
It equalizes air pressure on both sides of the eardrum and drains fluid from the middle ear.
When you swallow, yawn, or chew, the tube opens briefly—which is why these actions help relieve ear pressure during altitude changes.
Blockage from colds or allergies can cause muffled hearing or ear pain.
