Retrovisceral space

The retrovisceral space is divided into the retropharyngeal space and the danger space by the alar fascia. It is of particular clinical importance because it is a main route by which oropharyngeal infections can spread into the mediastinum.

Anatomical terminology

Some sources say the retrovisceral space is the same as the retropharyngeal space.[1]

Other sources say that the retrovisceral space is "continuous superiorly" with the retropharyngeal space.[2]
