Overview of Dilated Eustachian Tubes

dilated eustachian Tube (PET) occurs when the Eustachian tube remains open most of the time. This is a rare condition that affects only about 1 in 10,000 people. The Eustachian tube, also known as the auditory tube, runs from the inner ear to the back of the throat.

Unlike PET, the Eustachian tube should be in a closed position to protect your inner ear from bacteria, viruses, and fluids. To equalize pressure and drain any fluid in your inner ear, your Eustachian tube opens once or twice an hour. It also turns on when you swallow, yawn or sneeze. It stays open for about half a second.

This article explains the symptoms and causes of a dilated Eustachian tube, as well as the non-invasive and invasive methods doctors use to treat it.

PET symptoms

If you are undergoing PET, you may experience one or more of the following symptoms:

  • I feel like my ears are blocked
  • automatic soundor hear your own voice in your ear
  • tinnitus, tinnitus

Spontaneous vocalization is a typical hallmark symptom of dilated Eustachian tubes. In this case, you will hear feedback that your voice, breathing, and heartbeat are unusually loud.Spontaneous vocalization is a symptom of other disorders involving the ear, such as the superior semicircular canal splitan abnormal opening in the ear canal.

What type of tinnitus are you experiencing?


The cause of PET is what medical experts say idiopathic, Means their origin is unknown. However, there are several factors that can cause you to have a long-term open Eustachian tube, including:

  • Chewing gum excessively
  • frequent and forced nose blowing
  • high levels of estrogen (such as pregnancy, birth control pills, or hormone replacement therapy)
  • nasal decongestant
  • Neurological disorders, such as stroke, multiple sclerosis, or facial nerve trauma
  • Radiation therapy to the head or neck
  • Significant and rapid weight loss
  • temporomandibular Joint syndrome (TMJ) or malocclusion

non-invasive treatment

Before getting treatment, you may find that sniffing or lowering your head can temporarily relieve narcissism. Mild symptoms may not require any treatment.

However, if symptoms are severe enough and persist for more than six weeks, then you will need to start treatment that focuses on addressing the dilated Eustachian tube.

Hydration is essential

Initial treatment includes proper hydration. Drinking enough water is essential, supplementing with nasal saline or rinsing the nose to help keep the mucous membranes moist.

The most common treatment for a dilated Eustachian tube is a nasal spray. Brine is the most common choice in the United States. While many inner ear conditions can benefit from nasal decongestants or steroids, this practice may worsen PET symptoms. If this occurs, treatment should be discontinued.

If steroids are used, treatment should be tapered off under the supervision of a doctor to prevent rebound symptoms and withdrawal side effects. There is a lot of anecdotal support for nasal estrogen creams and other intranasal fillers. However, clinical evidence to support its use is still lacking.

invasive treatment

Surgery may be more effective when minimally invasive approaches prove insufficient to address dilated Eustachian tube symptoms.The most common surgical intervention is the placement of a tympanostomy tube. It keeps the ear open, provides ventilation, and allows excess fluid in the ear to drain. This procedure is only about 50% effective and may help resolve symptoms, make them worse, or do nothing at all.

Unfortunately, there is insufficient evidence to predict who will respond positively to ear tube surgery. However, ear tube placement is a fairly straightforward process with few side effects. If the synthetic tube does not provide relief, it can be removed.

Other more invasive treatments being studied include:

  • cauterize the Eustachian tube, destroying tissue with heat or chemicals
  • Eustachian tube injection with cartilage filler
  • Manipulate the muscles around the Eustachian tube
  • Place the cartilage in the Eustachian tube

Other options include inserting a catheter in the Eustachian tube or performing muscle tissue Manipulate to narrow the Eustachian tube. In the process, a small tool is used to manipulate muscles and other soft tissues. While the process does not restore the tube to normal function, it does reduce the amount of air flow into the middle ear. This helps reduce spontaneous symptoms.


There is insufficient evidence to predict which types of patients are likely to respond positively to surgical placement of ear tubes. But it’s a fairly simple process with few side effects. If synthetic tubes don’t provide relief, they can be easily removed.


A dilated Eustachian tube (PET) occurs when the Eustachian tube remains open. You may not know you have the disease unless you encounter some red flags. These feel like your ears are blocked, hear your own voice in your ears, or experience a loud sensation, a condition known as tinnitus. Of the three, the hallmark symptom of PET is the second, also known as idiopathic.

The cause of PET is not known, but it is thought that certain habits and conditions may predispose you to PET, from using nasal decongestants to losing a lot of weight quickly.

Many physicians turn to non-invasive treatments first. These treatments usually involve some form of proper hydration. The most common invasive treatment involves placing a tympanostomy tube in the ear. It keeps the ear open, provides ventilation, and allows excess fluid in the ear to drain. However, this process only works about half the time.

VigorTip words

Whether or not they’ve been diagnosed with PET, some people who develop symptoms turn to antihistamines or decongestants to relieve symptoms. In fact, some doctors may even recommend medications to treat Eustachian tube dysfunction. However, these drugs may not provide any relief. In some cases, they can even make symptoms worse. If any of these results occur, contact your doctor right away.

Frequently Asked Questions

  • Do Decongestants Help Eustachian Tube Dysfunction?

    Decongestants are unlikely to help with Eustachian tube dysfunction and will make the condition worse. Instead, treatment should include drinking plenty of water, limiting the use of decongestants and caffeine, and using medicated nasal drops or nasal saline. If none of these show signs of improvement, it is best to see a doctor for further treatment.

  • How is the Eustachian tube opened?

    The Eustachian tube opens when the muscles around it contract, usually triggered by yawning or swallowing. Air passing under pressure through the middle ear can also push open the Eustachian tube; this can happen when traveling by plane or driving through high altitudes.

  • What is spontaneity?

    Autophony is the experience of hearing your own voice and internal breathing function sounds (such as heartbeat and breathing) at uncomfortably high volumes. It is a symptom of dilated eustachian tube (PET) and superior canal dehiscence syndrome (SCDS).
