ICD-Code T70.1: Sinus barotrauma

Your paranasal sinuses were damaged by a rapid change in pressure.

There is a certain pressure in every environment. The pressure in the air is atmospheric pressure and decreases with increasing altitude. The pressure in water is water pressure and increases with depth.

For example, the ambient pressure changes when changing altitude or while diving. There are various air-filled cavities in the body that constantly adjust to the ambient pressure.

If the ambient pressure suddenly changes, then sometimes the pressure in the body’s air-filled cavities may not adjust as quickly. The paranasal sinuses are one example of an air-filled cavity in the body.

The paranasal sinuses are air-filled cavities in the skull. They are each connected to the nasal cavity via an opening that forms the inside of the nose. The paranasal sinuses are lined internally with mucous membrane. There are four different paranasal sinuses.

If the paranasal sinuses are damaged by a change in air pressure, the mucous membrane in the paranasal sinuses may become inflamed. There may then be a feeling of pressure in your head, for example. It may also be harder than usual to breathe through your nose.
