Airplane ear occurs when an imbalance in the air pressure in the middle ear and air pressure in the environment prevents your eardrum (tympanic membrane) from vibrating as it should. Air pressure regulation is the work of a narrow passage called the eustachian tube. One end is connected to the middle ear. The other end has a tiny opening where the back of the nasal cavity and the top of the throat meet (nasopharynx).
When an airplane climbs or descends, the air pressure in the environment changes rapidly, and your eustachian tube often doesn't react quickly enough. Swallowing or yawning activates muscles that open the eustachian tube and allow the middle ear to replenish its air supply, often eliminating the symptoms of airplane ear.
Ear barotrauma also may be caused by:
- Scuba diving
- Hyperbaric oxygen chambers
- Explosions nearby
You may also experience a minor case of barotrauma while riding an elevator in a tall building or driving in the mountains.
