The Eustachian tubes help to equalize the air pressure in your middle ears. When the tubes are open, they allow air to flow in and out. If the tubes are blocked, this is called Eustachian tube dysfunction. When this happens, sounds may be muffled and you may experience a sensation of ear fullness or discomfort.
Eustachian tube dysfunction is usually caused by the common cold, sinus infections or nasal allergies. It can also be caused by quick changes in elevation.
