Understanding Ear Barotrauma

Front view cross section of outer, middle, and inner ear showing pressure on both sides of eardrum.Ear barotrauma is a type of ear damage. It is caused by a difference in pressure between the inside of the ear and the air around you. It can cause pain and may lead to lasting hearing loss. It can harm the eardrum. The eardrum is between the outer and middle ear. Harm to the eardrum can cause bleeding or other damage to the outer, middle, or inner ear.

How pressure works in the ear

The middle ear is an air-filled hole. It sits between the inner and outer parts of the ear. It has 3 small bones that help send sound. It also has the opening of the Eustachian tube. This is a small tube that leads from the middle ear to an area behind the nose. This tube stays closed most of the time.

For your hearing to work, the pressure in the middle ear has to match the pressure in the air around you. If the pressure does not match, the Eustachian tube will open. This makes the pressure in the middle ear and the air around you the same.

What causes ear barotrauma?

It’s caused by a pressure difference that can happen during:

  • Scuba diving

  • Air travel

  • High pressure oxygen therapy for wound healing

  • Exposure to an explosive blast

Most people in these situations don’t get ear barotrauma. It only happens when the Eustachian tube does not open. Swelling or fluid buildup in the area around the tube can make it not open. This may be caused by:

  • Allergies

  • Sinus stuffiness

  • Having a cold or other infection

  • Anatomical problems

  • Contact with irritants like tobacco smoke

  • Certain hormonal changes (such as, during pregnancy)

Symptoms of ear barotrauma

Symptoms can be mild to severe. The most common symptoms of ear barotrauma may include:

  • Feeling of pressure in the ear

  • Ear pain

  • Dizziness

  • Feeling like you have a blocked ear

  • Bleeding from the ears or into the middle ear

  • Ringing in your ears

  • Hearing loss

Some events that cause ear barotrauma may also harm the lungs and sinuses. This can cause symptoms such as facial pain or shortness of breath.

Diagnosing barotrauma

Your healthcare provider will ask about your health history and your symptoms. You’ll be asked about recent events that may have cause ear barotrauma, such as air travel. He or she will give you a physical exam. This may include an exam of the ear, and hearing and balance tests.
