Severe Complications With Eustachian Tubes

Eustachian Tube Dysfunction Causes

Causes of eustachian tube dysfunction include the common cold, or infections of the throat, nasal, ear, or sinus. Thick mucus or a blocked nose from the common cold or an infection may cause the eustachian tube to become blocked. This occurs when the infection causes the lining of the tube to come swollen or infected, which usually occurs during the common cold. These symptoms can last up to one week. It is caused by trapped mucus and inflammation, which takes a while to clear even after the germs causing the infection have been removed.
