The Eustachian tube is a small channel that equalises pressure between your middle ear and the back of the nose. When it stops opening properly, you feel a persistent fullness, your hearing dulls, and the simple act of swallowing no longer "pops" the ears as it should.
ETD often follows a cold, an allergy flare, or a flight. For most people it resolves within a week or two. When it lingers, fluid can collect behind the drum (glue ear in adults), gradually muffling hearing.
Modern endoscopic balloon dilation is a minimally invasive option for stubborn cases that don't respond to medical management.
See us if symptoms last beyond two weeks, if there is significant hearing loss, or if you experience pressure or pain on flights despite over-the-counter measures. Long-standing ETD can lead to ear-drum retraction, which is better caught early.
