Danger space

Danger space is a potential space in the human body located in the neck. It is a deep fascial space that extends from the base of the skull to the level of the diaphragm. The danger space is clinically significant because infections can spread from the neck to the mediastinum, which can lead to mediastinitis, a serious condition.

Anatomy

The danger space is located between the prevertebral fascia and the alar fascia. It is a thin, sagittal plane that extends from the base of the skull to the level of the diaphragm. The danger space is so named because it provides a potential pathway for the spread of infections from the neck to the mediastinum.

Clinical significance

Infections in the danger space can spread to the mediastinum, leading to mediastinitis. This can occur as a result of dental abscess, pharyngitis, or tonsillitis. Mediastinitis is a serious condition that can lead to sepsis and shock, and requires immediate medical attention.
