Severe Complications With Eustachian Tubes
Ear Infection

Eustachian tube complications may arise as result of an ear infection. These tubes are responsible for creating an airway passage from the narrow tubes of the ear to the middle ear all the way to the high back of the throat, behind the nasal passages. The throat opens and closes to refresh the air in the ear, drain normal secretions from the middle ear, and regulate air pressure. During an upper respiratory infection, the Eustachian tubes become blocked and filled with fluid, which causes an ear infection.
