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