What is eustachian tube dysfunction?
The eustachian tubes are small passageways that connect the upper part of your throat (pharynx) to your middle ears. When you sneeze, swallow or yawn, your eustachian tubes open, allowing air to flow in and out. But sometimes a eustachian tube might get plugged. This is called eustachian tube dysfunction. When this happens, sounds may be muffled and your ear may feel full, or you may have ear pain.
