Eustachian Tube Dysfunction: Why Does the Ear Feel Pressurised or Full?

The Eustachian tube links the middle ear to the back of the nose. It briefly opens during swallowing to balance pressure and help clear middle-ear secretions. Dysfunction can cause pressure, fullness, popping, or muffled hearing. Because earwax, middle-ear fluid, and sudden inner-ear hearing loss can feel similar, symptoms alone do not establish the diagnosis.

In obstructive dysfunction, the tube does not open adequately and negative middle-ear pressure may develop. Baro-challenge symptoms arise mainly during flying, diving, or rapid altitude change, while tests may look normal at rest. With a patulous tube, the passage remains too open and a person may hear their own voice and breathing loudly. Correct typing matters because advice for one form can aggravate another.

Assessment starts with onset, duration, one- or two-sided symptoms, pressure triggers, allergy, and infection history. Otoscopy can show eardrum retraction or fluid, tympanometry measures middle-ear pressure, and audiometry measures hearing. Eardrum movement with breathing may support a patulous tube. Persistent unilateral findings may prompt nasoendoscopy; imaging is selected for suspected alternative disease rather than used routinely.

The goal is not simply to ‘open the ear’ but to identify the type and contributing problem. Brief post-viral symptoms may be observed; allergy or nasal disease is managed when present. Pressure-equalising manoeuvres may help some people but should not be forced through pain. Tubes or balloon dilation are discussed only for appropriately selected chronic obstructive disease.

ENT assessment is appropriate for symptoms beyond three months, recurrent or unilateral pressure, or meaningful effects on hearing and daily life. Sudden hearing loss, severe vertigo, blood or discharge, symptoms after trauma, facial weakness, or neurological signs require urgent assessment. A safe plan before flying also begins with the correct diagnosis.
