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.
The eustachian tube is surrounded by muscles that function to open and close the tube depending on the situation. This allows for ânormalâ functioning of the tube. Often, the Eustachian Tube functions poorly leading to ear infections and fluid build-up in the middle ear cavity. This occurs because the tube does not open appropriately. Patient with Patulous Eustachian Tube (PET) have the opposite problem, with the eustachian tube remaining open and not closing appropriately.
