What Is Subcutaneous Emphysema?
1. Subcutaneous Emphysema
Subcutaneous emphysema is a condition that means that air is able to find itself in the tissues of the skin, and there it can become trapped. It is often quite visible from the surface as it can cause the skin to bulge outward. In addition, it will also often cause a crackling sensation when pressure is placed on it. This crackling is known as crepitus, and it happens because the air is being forced through the patients tissues. Subcutaneous emphysema will usually occur in the neck or in the chest, but it can occur elsewhere in the body. It is quite common, and how serious it is will depend on the underlying cause.
