3. What is the Eustachian tube and why does it matter for my ears?The Eustachian tube is a tiny canal that connects the middle ear to the back of the throat. It helps keep the ear pressure balanced and clears mucus so we can hear and feel comfortable.
4. How does the Eustachian tube open when we fly or dive?Muscles in the throat, like the tensor veli palatini, lift the tube when we swallow or yawn, letting air move in or out of the ear to equalize pressure.

Barotrauma: Injury caused by pressure differences between a body cavity and the surrounding environment.
Otitis Media: Inflammation or infection of the middle ear.
Eustachian Tube Dysfunction (ETD): A condition where the Eustachian tube fails to equalize pressure properly.
