Eustachian tube dysfunction
Blocked ears or unusually loud sounds of your own voice or breathing can involve the Eustachian tube, which connects the middle ear to the back of the nose. Obstructive and patulous dysfunction need different assessments.

Obstructive and patulous dysfunction
The tube normally opens briefly when swallowing and remains closed at rest. Obstructive dysfunction involves difficulty opening; patulous dysfunction involves inadequate closure.
Pressure, nasal symptoms and altitude changes may suggest obstruction. Loud self-voice or breathing, posture-related changes and weight loss can be clues to patulous dysfunction. Symptoms alone are insufficient for diagnosis.
When to seek care
Consult ENT for persistent blockage or bothersome self-voice sounds. Sudden hearing loss needs prompt assessment, ideally the same day. Neurological symptoms with severe dizziness need emergency care.
Assessment at our clinic
We ask about the onset, side, nasal symptoms, pressure changes and posture. We examine the ears and nose and consider hearing testing. Wax, middle-ear fluid and inner-ear disorders must also be considered.
Specialist Eustachian tube tests may require evaluation at another institution.
Treatment principles
Management depends on the type and associated conditions such as rhinitis. Avoid forceful ear-popping or repeated sniffing without advice. Persistent symptoms or a need for specialist procedures may require further evaluation elsewhere.
Frequently asked questions
Should I seek care without pain?
Yes, persistent blockage or a hearing change warrants assessment. A sudden hearing change is particularly urgent.
Will popping my ears fix it?
It depends on the cause. The same approach is not suitable for every type, and forceful repeated pressure manoeuvres may harm the ear.
