Eustachian Tube Dysfunction: Causes, Symptoms, & Treatment

A recently developed procedure may help millions of people struggling with Eustachian tube dysfunction (ETD) without the need for surgery or constant medication. Eustachian tube balloon dilation is an FDA-approved procedure that has been shown to help people with chronic ETD by resolving the source of the problem rather than treating symptoms alone.

5 Not So Well Known / Surprising Facts About Eustachian Tube Dysfunction and Allergies

  • đź“Ź Size and Functionality: The Eustachian tube, though only about 1.5 inches long and 3 mm in diameter, is critical in regulating ear pressure, protecting the ear from internal sounds, and draining fluids from the middle ear.
  • 🗣️ Self-Sound Perception: When the Eustachian tube stays open too much, individuals may experience autophony, hearing their voice, breathing, and other body sounds more loudly than usual.
  • 🤧 Allergic Rhinitis Impact: Allergic rhinitis, commonly known as hay fever, is a significant contributor to Eustachian tube dysfunction, causing symptoms such as clogged ears, hearing loss, and increased ear pressure due to the narrowing of the Eustachian tube passageway.
  • đź©ş Rare Causes: While upper respiratory infections are common causes, rare causes of Eustachian tube dysfunction include nasal tumors, cleft palate, and tumors at the base of the skull.
  • 🌸 Treatment Approaches: Managing underlying allergies through nasal corticosteroids, oral or nasal decongestants, antihistamines, and allergy immunotherapy (effective in 80-85% of patients) can significantly reduce Eustachian tube dysfunction symptoms.

What Is Eustachian Tube Dysfunction (ETD)?

The Eustachian tube is a small tubular passageway connecting the middle ear to the back of the nose and upper throat. It plays a vital role in regulating ear pressure, protecting the ear from internal sounds, and draining fluids. Eustachian tube dysfunction (ETD) occurs when this tube fails to open properly, causing symptoms like ear pressure, pain, hearing loss, and tinnitus.

ETD affects roughly 11 million adults in the U.S., with a prevalence of 4.6% nationwide, so it’s a widespread issue.

Causes of Eustachian Tube Dysfunction

Upper Respiratory Infections

Upper respiratory infections, such as the common cold, flu, or sinus infections, are common causes of ETD. These infections can cause inflammation and blockage of the Eustachian tube.

Allergies

Allergic rhinitis, commonly known as hay fever, is another significant cause of ETD. Allergies can cause inflammation and narrowing of the Eustachian tube, leading to symptoms like ear pressure, pain, and hearing issues.

Symptoms of Allergic Rhinitis

  • Runny nose
  • Nasal congestion
  • Sneezing
  • Post-nasal drip
  • Itchy and watery eyes
  • Sinus pain and pressure

Impact on Eustachian Tube

Allergies can lead to the narrowing of the Eustachian tube, causing symptoms such as clogged ears, hearing loss, increased ear pressure, ear pain, popping sounds, vertigo, dizziness, and tinnitus.

Eustachian Tube Dysfunction Causes

ETD has several potential causes, including the following.

Cold and Sinus Infections: ETD often results from the common cold or sinus infections. In these instances, the Eustachian tube becomes inflamed or blocked by thick mucus, restricting airflow. Typically, this only lasts a week or two after the infection clears up.

Smoking: It can also be caused by smoking, including second-hand smoke. For instance, one study found that about 6.1% of children aged 12 to 19 who were exposed to environmental tobacco smoke had ETD.

Glue Ear: Often, children might experience ETD as a result of glue ear, in which a glue-like substance fills the middle ear, congesting the Eustachian tube and tightening the eardrum.

Seasonal Allergies: Finally, allergies are another frequent cause. Seasonal allergies such as hay fever lead to congestion and inflammation that may restrict airflow through the Eustachian tube for months at a time.

For instance, Los Angeles experiences high tree pollen counts from December through June; after that comes grass pollens through September, which are then followed by weed pollens through November. Las Vegas has two allergy seasons—one in the spring and then ragweed season in the fall. Depending on where you live and your exact allergies, that can mean months of nonstop congestion and ETD.

ETD Symptoms

ETD is often characterized by the following symptoms:

  • Muffled or dull hearing as the eardrum is pulled taut
  • A sensation of fullness or water inside your ear
  • Tinnitus (or ringing in your ear)
  • Dizziness
  • Intermittent ear pain (typically not constant)

These symptoms often only last a few hours, but chronic ETD could result in these symptoms lasting for weeks or even months.

How Can ETD Be Treated?

In most cases, ETD goes away on its own. For instance, Eustachian tube dysfunction might last a week or two after a cold as mucus residue drains out. However, if it persists, several possibilities exist, such as nasal sprays, antihistamines, or nose drops, but these may only provide temporary relief. A more permanent solution to chronic ETD is Eustachian tube balloon dilation.

Treating the underlying allergy is crucial for managing ETD. Treatment options include:

  • Nasal corticosteroids
  • Oral or nasal decongestants
  • Oral and nasal antihistamines
  • Allergy immunotherapy (allergy shots)

How Eustachian Tube Balloon Dilation Helps with ETD

Eustachian tube balloon dilation utilizes a narrow rod with a balloon at the end that’s inserted into the Eustachian tube through the nose. The balloon is then filled up with a saline solution to expand the tube. After being left for a few minutes, the balloon is deflated and removed.

Success Rate

Studies show that balloon dilation is highly effective, with one study showing an 81% success rate a year after the procedure. Another study found similar rates of success after 5 years, making this procedure a safe and effective way to treat ETD.

Advantages of ET Balloon Dilation

Eustachian tube balloon dilation promises to be an effective alternative to ear tubes for adults as well as other treatments that only tackle symptoms. With enduring results from a single procedure and no need for constant medication, it is a safe, effective, and efficient way to treat Eustachian tube dysfunction.

Eustachian Tube Dysfunction and Balloon Dilation FAQs 

Common questions on ETD and Eustachian tube balloon dilation include the following.

Can allergies cause Eustachian tube dysfunction?

Yes. The inflammation and excess mucus caused by allergies can restrict airflow through the Eustachian tube to the middle ear.

How long can Eustachian tube dysfunction last?

It depends on the exact cause. Usually, it only lasts a few weeks at most, but chronic ETD resulting from allergies can last several months at a time.

How effective is Eustachian tube balloon dilation?

Studies and clinical trials show very favorable rates of success for balloon dilation. It is a highly effective treatment.

How long does it take Eustachian tube dilation to work?

The procedure itself only takes a few minutes, and the results are instant. That said, you may experience some pain and soreness for a day or two. Also, avoid strenuous activity and popping your ears for at least a week.

What happens if Eustachian tube dysfunction is left untreated?

Chronic ETD may lead to dizziness, upper respiratory tract infections, and (rarely) loss of hearing if it’s left untreated long enough.

Is Eustachian Tube Balloon Dilation Right for You?

Eustachian tube balloon dilation is quick, safe, and effective, but the only way to be sure whether it’s right for you is to talk to an ENT specialist like Dr. Kayem.
