Summary Information: Eustachian tube

Eustachian tube: The eustachian tube is a tiny tube that connects the middle ear to the nasopharynx. The function of the eustachian tube is to allow air to flow in and out of the air-filled middle ear cavity. A normally functioning eustachian tube keeps the air pressure inside the middle ear the same as the air pressure outside the ear, which is necessary for the optimal vibration of the tympanic membrane and acute hearing. The eustachian tube allows the ear to "pop" and maintain normal pressure when there are changes in altitude, such when flying.

The eustachian tube is very short in children, which more easily allows infections to spread from the nasopharynx into the middle ear, resulting in otitis media. Other conditions that can afflict the eustachian tube include strep infection and trauma.
