Ear - blocked at high altitudes
High altitudes and blocked ears; Flying and blocked ears; Eustachian tube dysfunction - high altitudeThe air pressure outside of your body changes as altitude changes. This creates a difference in pressure on the two sides of the eardrum. You may feel pressure and blockage in the ears as a result.
Pressure and blockage in the ears
Ear barotrauma causes discomfort in the ear due to pressure differences between the inside and outside of the eardrum. It may include damage to the ...
Information
The eustachian tube is a connection between the middle ear (the space behind the eardrum) and the back of the nose and upper throat. This structure connects the middle ear space to the outside world.
Swallowing or yawning opens the eustachian tube and allows air to flow into or out of the middle ear. This helps equalize pressure on either side of the eardrum.
Swallowing or yawning can unclog blocked ears when you are going up or coming down from high altitudes. Chewing gum the entire time you are changing altitudes helps by causing you to swallow often. This may prevent your ears from getting blocked.
People who always have blocked ears when flying may want to take a decongestant about an hour before the flight leaves.
If your ears are blocked, you can try breathing in, then gently breathing out while holding your nostrils and mouth closed. Use care when doing this. If you breathe out too forcefully, you can cause ear infections by forcing bacteria into your ear canals. You can also create a hole (perforation) in your eardrum if you blow too hard.
Ear infections
Otitis is a term for infection or inflammation of the ear.

The ear consists of external, middle, and inner structures. The eardrum and the 3 tiny bones conduct sound from the eardrum to the cochlea.

Medical findings based on ear anatomy - illustration
The external structures of the ear may aid in diagnosing some conditions by the presence or absence of normal landmarks and abnormal features including earlobe creases, preauricular pits, and preauricular tags.

The ear is a complicated organ controlling hearing and balance. When sounds waves reach the ear, they are translated into nerve impulses. These impulses then travel to the brain where they are interpreted by the brain as sound.
