The eustachian tubes are small passageways that run between the middle ear and the throat, opening only when you chew, swallow, sneeze or yawn. They are responsible for equalizing pressure in the middle ear and facilitating proper drainage.
The eustachian tubes can get blocked for any number of reasons, leading to inner-ear pain, fullness and difficulty hearing. Affecting both children and adults, this is a common condition referred to as Eustachian Tube Dysfunction (ETD).
