Barotrauma is the pain or discomfort that is felt with a difference in air or water pressure between the outside environment and the inside of the body.
Any part of the body that contains air can be sensitive to these pressures:
Normally air moves easily between outside and inside of the ear, sinuses, and lungs, helping to maintain a balance of pressure. Imbalances may be created with:
The imbalance of pressure causes the air inside your body to shrink or swell. This is what can cause pain and damage.
Activities that can expose someone to significant pressure changes include:
The inner ear is connected to outside air through tubes to keep inner and outer pressure balanced. Blockages and congestion in these tubes increase the risk of ear barotrauma because the inside pressure is not allowed to change to match the outside pressure. These tubes may be blocked or limited by:
Similarly, blockages in the sinuses will block the flow of air from outside to inside the body. Sinuses may be impaired by:
Pulmonary barotrauma may be more likely in those with damage from previous or current lung conditions.
Other factors that may affect the ability for air spaces in the body to work properly include:
Symptoms will depend on what areas are affected.

Sinus barotrauma may cause:

Pulmonary barotrauma is serious and needs immediate medical attention. Treatment will depend on the specific lung problem that is present.
The following measures can also prevent barotrauma. Treatment options include the following:
Pressure can be relieved with self-care and medications.
To relieve the pressure in the eustachian tube, you can:
It is important to relieve nasal congestion and open your eustachian tube. Medications to relieve ear and sinus pressure include:
Pain relievers can be used if ear or sinus pressure is causing pain. Antibiotics may be used if a bacterial infection is present or possible.
Emergency medical care may include:
Surgery may be necessary to relieve the pressure if your eustachian tube does not open with other treatments. Your doctor will make a small cut in your eardrum to equalize the air pressure. Any fluid blocking the tube may also be removed.
To help reduce your chances of barotrauma during:
To help your baby through pressure changes, give your baby a pacifier or bottle during landing and take off.
