The Eustachian tube connects your neck to your middle ear and is a tiny canal.
The Eustachian tube, which is mucous-lined like the lining of the nose and throat, connects the middle ear to the base of the back of the tongue. The Eustachian tube is made up of small bones that carry sound to the ear.
The Eustachian tubes open when you cough, swallow, or yawn. This prevents the buildup of air pressure and moisture inside your ear.
