• Symptoms of eustachian tube dysfunction (ETD) include fullness in the ears, feeling like your ears are plugged, changes in hearing, tinnitus, and pain. 
• Some people are at a higher risk for ETD, including those struggling with obesity, smokers, and people with allergies. 
• If left untreated, the symptoms of ETD are likely to recur.

Eustachian tube dysfunction is a disorder in which passageways in the ears are plugged up and cause uncomfortable symptoms. According to Dr. Brian Lee of the Scottsdale Sinus and Allergy Center, the eustachian tubes can be affected by sinus issues. 

"The eustachian tubes drain out to the back of the nose. So essentially anything that inflames the sinuses could be allergies," Dr. Lee told the Grand Canyon Times. "Chronic sinus issues can cause inflammation around the eustachian tube to cause it to plug up as well."

According to Healthline, eustachian tubes are small tubes that run between your middle ears and the upper throat. They are responsible for equalizing ear pressure and draining fluid from the middle ear, the part of the ear behind the eardrum. The eustachian tubes are typically closed except during chewing, swallowing, or yawning. 

These passageways are small in size and can become plugged due to a variety of reasons, according to Healthline. Blocked eustachian tubes can cause symptoms, including pain, hearing difficulties, and a feeling of fullness in the ears, which is referred to as eustachian tube dysfunction (ETD). Depending on the cause, it may resolve on its own or through simple at-home treatment measures. ETD is a relatively common condition, though severe or recurring cases may require a visit to the doctor.

ETD can be caused by allergies, a common cold, the flu, or chronic acid reflux, according to the Cleveland Clinic. ETD frequently resolves on its own, but patients are advised to consult a physician if symptoms persist for more than two weeks. At-home remedies to address ETD include chewing gum, yawning, swallowing, or saline nasal sprays. People with ETD due to allergies can treat their symptoms with an antihistamine or other over-the-counter medications.

According to Scottsdale Sinus and Allergy's website, Dr. Brian Lee graduated from Loma Linda University School of Medicine as a member of the Alpha Omega Alpha Honor Society. He subsequently completed his internship and residency in otolaryngology (head and neck surgery) at the University of Southern California. Dr. Lee was recognized as one of the Valley's "Top Doctors" by Phoenix Magazine in both 2015 and 2016.
