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 .
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.

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 carotid sheath is situated at each lateral boundary of the retropharyngeal space, [3] deep to the sternocleidomastoid muscle. [ 2 ] : 579 [ 3 ] [ 2 ] The pharynx is situated medial to the carotid sheath, (in the suprahyoid region) the parotid gland laterally to it, in the suprahyoid region the infratemporal fossa anterior to it, and the ...
The retropharyngeal space is found anterior to the danger space, between the alar fascia and buccopharyngeal fascia. There exists a midline raphe in this space so some infections of this space appear unilateral. The retropharyngeal space drains into the superior mediastinum, whereas the danger space drains into the posterior mediastinum.
The parapharyngeal space (also termed the lateral pharyngeal space), is a potential space in the head and the neck. It has clinical importance in otolaryngology due to parapharyngeal space tumours and parapharyngeal abscess developing in this area.
