The retropharyngeal space (abbreviated as "RPS" [1] [2]) is a potential space [2] [3] and deep compartment of the head and neck [1] situated posterior to the pharynx. [4] The RPS is bounded anteriorly by the buccopharyngeal fascia , posteriorly by the alar fascia , and laterally by the carotid sheath .

At the base of this recess is the retropharyngeal lymph node (the node of Rouvière). This is clinically significant in that it may be involved in certain head and neck cancers , notably nasopharyngeal cancer .
The retropharyngeal lymph nodes, from one to three in number, lie in the buccopharyngeal fascia, behind the upper part of the pharynx and in front of the arch of the atlas, being separated, however, from the latter by the longus capitis. Their afferents drain the nasal cavities, the nasal part of the pharynx, and the auditory tubes.
Retropharyngeal abscess (RPA) is an abscess located in the tissues in the back of the throat behind the posterior pharyngeal wall (the retropharyngeal space).Because RPAs typically occur in deep tissue, they are difficult to diagnose by physical examination alone.
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. Some sources say the retrovisceral space is the same as the retropharyngeal space. [1]
Acute calcific tendinitis of the longus colli muscle can occur. This presents with acute onset of neck pain, stiffness, dysphagia and odynophagia, and must be distinguished from retropharyngeal abscess and other sinister conditions. Imaging diagnosis is by CT or MRI, demonstrating calcification in the muscle in addition to retropharyngeal oedema.
The danger space or alar space, is a region of the neck. [1] The common name originates from the risk that an infection in this space can spread directly to the thorax, and, due to being a space continuous on the left and right, can furthermore allow infection to spread easily to either side.
