Eustachian Tube Dysfunction: Symptoms, Causes and Treatment

01What

What is the Eustachian tube?

The Eustachian tube is a narrow channel, about 3–4 cm long in adults, connecting the middle ear to the back of the nose. It is normally closed and opens briefly when you swallow, yawn or chew, letting air into the middle ear and equalising pressure with the outside. It also drains small amounts of fluid and protects the ear from nasal secretions. In children it is shorter and more horizontal, which is why they are more prone to problems.

02Symptoms

Symptoms of ETD

• A feeling of fullness or blockage in one or both ears.
• Muffled hearing.
• Popping, clicking or crackling noises when swallowing.
• Mild ear pain or pressure, sometimes worse with altitude changes.
• Tinnitus or a feeling of “water in the ear”.
• Occasional dizziness or imbalance.
• Symptoms usually come and go and often follow a cold or allergy.

03Causes

Causes

• Colds and sinus infections, with swelling of the lining of the nose and tube.
• Allergic rhinitis.
• Rapid pressure changes: flying, diving, mountain driving.
• Enlarged adenoids in children, and nasal polyps or masses.
• Reflux, smoking and irritants.
• Craniofacial differences, such as cleft palate.
• Patulous Eustachian tube (a tube that stays open) is a different condition with autophony and breathing sounds in the ear.

04Home

Self-care

• Swallow, yawn or chew gum frequently.
• Gentle Valsalva: pinch the nose, close the mouth and blow very gently as if blowing up a balloon.
• Saline nasal spray or rinse to reduce congestion.
• Steam or a warm shower.
• Avoid smoking and irritants.
• Do not use cotton buds or insert objects in the ear.
• Avoid flying or diving when you are very congested, if possible.

05Medicines

Medicines

Nasal steroid sprays reduce inflammation of the nose and tube lining, and are the most commonly used treatment for ETD due to allergy; they take 1–2 weeks to reach full effect. Antihistamines help if allergy is the trigger. Short courses of decongestant sprays (not more than 3–5 days) or tablets can help temporarily, but oral decongestants should be avoided in people with high blood pressure or heart disease. Oral steroids are sometimes used for severe cases. Antibiotics do not help unless there is a bacterial infection. Evidence for many popular ETD treatments is limited, so your doctor will individualise advice.

06ENT

When ENT treatment is needed

If ETD lasts longer than three months, keeps returning or causes hearing loss, retraction of the eardrum or fluid, an ENT specialist will examine the ear and nose (often with a small camera), test the hearing and eardrum movement (tympanometry) and treat the cause. Options include treating allergy and nasal disease, grommets (small ventilation tubes in the eardrum) to ventilate the middle ear, and for selected adults, balloon dilation of the Eustachian tube, a procedure in which a small balloon widens the tube opening.

07Flying

Flying and diving with ETD

• Use nasal decongestant spray 30–60 minutes before descent if appropriate.
• Swallow, chew or yawn throughout descent; do not sleep through landing.
• Consider a gentle Valsalva during descent.
• Do not fly if you have a significant ear infection or very blocked nose, unless advised.
• Scuba divers should not dive with ETD.
• Special filtered earplugs can slow pressure changes for some people.

08Children

ETD in children

Children are prone to ETD and middle ear fluid after colds, with muffled hearing, speech delay or inattention in class. Most cases clear in 3 months. If fluid persists with hearing loss, the doctor may suggest grommets and sometimes removal of adenoids. See crackling in the ear for more.

10Cases

Three common situations

Blocked ear after a cold: saline, steam, swallowing; most settle in a couple of weeks.

Ear popping and fullness every pollen season: consider a nasal steroid and antihistamine plan.

Blocked ear after a flight, lasting a week: see a doctor to exclude barotrauma and fluid.

11Myths

Myths about blocked ears

Cotton buds, ear candles and syringing do not fix Eustachian tube problems: the blockage is behind the eardrum, not in the canal. Holding your nose and blowing hard can do harm and should be gentle. Antibiotics do not work for non-infectious ETD. Time, nasal care and treating allergy are the foundations of recovery.

12Summary

Key points to remember

ETD is common and mostly temporary. Treat the nose and allergy, use simple measures to open the tube and seek ENT assessment if symptoms are chronic or severe.
