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 danger space serves as an important pathway for complicated infections of the posterior pharynx to enter the chest and spinal column. Anterior to the parapharyngeal space is the masticator space which contains the lower dental row, muscles of mastication, the inferior alveolar nerve as well as branches of cranial nerve V.
The buccopharyngeal fascia envelops the superior pharyngeal constrictor muscles. [ 4 ] [ 1 ] It extends anteriorly from the constrictor pharyngis superior [ 4 ] over the pterygomandibular raphe to cover the buccinator muscle [ 1 ] (though another source describes it as continuous with the fascia covering the buccinator muscle).
In the case of the pharyngeal reflex: the sensory limb is mediated predominantly by CN IX (glossopharyngeal nerve) the motor limb by CN X (vagus nerve). The gag reflex involves a brisk and brief elevation of the soft palate and bilateral contraction of pharyngeal muscles evoked by touching the posterior pharyngeal wall. Touching the soft palate ...
[citation needed] It is formed as a thickening of the pharyngeal mucosa superior to the superior pharyngeal constrictor muscle. It attaches to the basilar part of occipital bone, the petrous part of the temporal bone (medial to the pharyngotympanic tube), the (posterior border of the) medial pterygoid plate, and the pterygomandibular raphe. It ...
Multiview videofluoroscopy is a radiographic technique to view the length and movement of the velum (soft palate) and the posterior and lateral pharyngeal (throat) walls during speech. The advantage of this technique is that the entire posterior pharyngeal wall can be visualized. Disadvantages include the following: 1.
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
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.
