Danger space
Danger Space
The Danger Space (pronunciation: dayn-jer speys) is a potential space in the human neck. It is a deep compartment situated posterior to the retropharyngeal space, extending from the base of the skull to the posterior mediastinum.
Etymology
The term "Danger Space" is derived from the potential risk it poses for the spread of infections. Due to its anatomical location, infections in this space can rapidly spread to the mediastinum, leading to life-threatening conditions such as mediastinitis.
Anatomy
The Danger Space is bounded anteriorly by the alar fascia and posteriorly by the prevertebral fascia. It extends from the base of the skull to the level of the diaphragm. This space allows for the potential spread of infections from the neck to the posterior mediastinum.
Clinical Significance
Infections in the Danger Space can lead to serious complications due to its anatomical continuity with the mediastinum. These infections can result from various sources, including dental infections, foreign bodies, or surgical procedures. The most common clinical presentation is retropharyngeal abscess, which can lead to mediastinitis, a life-threatening condition if not promptly treated.
