Severe Complications With Eustachian Tubes
Impacted Earwax

Earwax is a yellowish and waxy substance lining the inside of the ear canal. Wax is used to protect the ear from foreign objects, injury, infection, and water. But when there's too much wax built up, it can cause problems. The buildup is referred to as impacted earwax. Impacted earwax can be related to eustachian tube dysfunction when it blocks the eustachian tube, or when the eustachian tube is too narrow to cope with the amount of earwax in the ear. The ear contains glands that make secretions which combine with dead cells to make earwax. Over time, earwax migrates from the inner ear canal to the outer portion of the ear. But if the ear canal is blocked, the wax may build up without naturally migrating to the outside of the ear. Impacted earwax may also occur due to individuals sticking things into their ears, such as cotton swabs, which is why this should not be done.
