The Eustachian tube is a passageway that connects the interior of the ear to the back of the throat and nasal cavity. A Eustachian tube that is functioning properly will open when you yawn, chew, or swallow. This important canal protects the middle ear from disease and controls pressure in the middle ear. When it’s not functioning properly, Eustachian tube dysfunction (ETD) can occur and cause discomfort and symptoms such as a blocked sensation in the ears.
ETD is caused when the Eustachian tube gets clogged and is prevented from opening. Plugging can be the result of inflammation or swelling due to allergies or sinus infection that causes mucus to build up and plug the Eustachian tube. Mild cases can often be resolved with medication to treat the allergy or sinus issues causing ETD. For those with recurring or severe ETD, Eustachian tube balloon dilation can be an ideal treatment option.
