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 the canal that connects your middle ear to your throat. When the Eustachian tube is open as it is normally, it prevents fluid and air pressure from building up inside the ear. Infections like colds, the flu, or allergic reactions can cause the Eustachian tube to become swollen and blocked.he Eustachian tube is the canal that connects your middle ear to your throat.
