The middle ear is an air-filled cavity separated from the external ear canal by the tympanic membrane (eardrum). The Eustachian tube connects the middle ear to the nasopharynx (back of the throat). Under normal conditions, this tube opens during swallowing, yawning, or jaw movement to equalize pressure.
During a flight’s ascent, ambient pressure decreases, causing the middle ear pressure to become relatively higher than the cabin pressure—the eardrum bulges outward, and the Eustachian tube opens passively to release excess pressure. cabin pressure increases rapidly, compressing the middle ear air volume. The Eustachian tube, which collapses during increased external pressure, must be actively opened to allow high-pressure air from the nasopharynx to re-enter the middle ear. Failure to do so results in a relative vacuum in the middle ear, retracting the eardrum inward—the sensation of a “blocked” ear. how to pop ear after flight
