What Are Eustachian Tubes? According to WebMD, âThe Eustachian tubes connect the middle ears to the back of the throat. The tubes help the ears drain fluid. They also keep air pressure in the ears at the right level. When you swallow or yawn, the tubes open briefly to let air in to make the pressure in the middle ears equal to the pressure outside of the ears. Sometimes fluid or negative pressure gets stuck in the middle ear. The pressure outside the ear gets too high. This causes ear pain and sometimes trouble hearing,â resulting in something known as Eustachian Tube Dysfunction.
Eustachian tubes are small tubes that run between your middle ears and the upper throat. They are responsible for equalizing ear pressure and draining fluid from the middle ear, the part of the ear behind the eardrum. The eustachian tubes are usually closed except for when you chew, swallow, or yawn. These passageways are small in size and can get plugged for a variety of reasons. Blocked eustachian tubes can cause pain, hearing difficulties, and a feeling of fullness in the ears. Such a phenomenon is referred to as eustachian tube dysfunction (ETD).
