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 connects the middle ear cavity with the part of the body called the nasopharynx. The opening and closing function of the middle ear not only regulates the pressure in the ear, but it helps protect the eardrum from loud noises. When the Eustachian tube is not working properly, there are numerous symptoms that can appear. There can be pain in the area due to the unequal pressure between the middle ear and the rest of the area. Dizziness can occur from the incorrect pressure in the head. The tube not working properly can be one of the main causes of ringing in the ears.
