Danger space

Danger space
Section of the neck at about the level of the sixth cervical vertebra. Showing the arrangement of the fascia coli.

The danger space is a region of the neck.^[1]

Anatomy

It is bounded superiorly by the skull base, anteriorly by the alar fascia and posteriorly by the prevertebral fascia. It comes to an end at the level of the diaphragm.

The retropharyngeal space is found anterior to the danger space between the buccopharnygeal fascia and alar fascia. There exists a midline raphe in this space so some infections of this space appear unilateral.

History

It was first characterized in 1938.^[2][3]

Clinical significance

It gets its common name from the risk that an infection in this space can spread directly to the thorax, it is sometimes also referred to as the Alar space. It is a median space without a midline raphe and hence infection can spread easily to either side.
