Axial unenhanced T1-weighted spin-echo MR image obtained at nasopharynx level shows fat-filled prestyloid parapharyngeal space (asterisks) located between masticator space and pharyngeal mucosal space. Torus tubarius represents …
Parapharyngeal Space - an overview | ScienceDirect Topics
The parapharyngeal space is a largely fat-filled spaced in the suprahyoid neck that has been variably described by anatomists, head and neck surgeons, and radiologists. 1–6 The bilateral parapharyngeal spaces are regions in neck that have historically been subdivided by surgeons into prestyloid and retrostyloid compartments. 4 The more ...

The parapharyngeal space (also termed the lateral pharyngeal space or prestyloid parapharyngeal space), shaped like a cone or a pyramid, inverted with its base at the sphenoid bone, with its apex inferiorly pointing to the greater cornu of the hyoid bone. It occupies the space between muscles of mastication and the muscles of deglutition.

2012年5月11日 · The prestyloid space (clear stars) extends inferomedially to continue to a space surrounding the constrictor pharyngis superior muscle (CPS in c). The prestyloid space posterior fascia (arrowheads in a–c) extends along the medial aspects of these two muscles.
parapharyngeal space is a deep potential neck space shaped as an inverted pyramid extending from the base of the skull to the hyoid bone. The dif-ferentiation of a prestyloid lesion from a post-styloid lesion is critical for guiding the surgeon in both the differential diagnosis as well as the potential surgical approach.

Results: A definite posterior marginal fascia of the space was seen along the anterior aspect of the stylopharyngeus and styloglossus muscles. Inferiorly, the prestyloid space faced the bucallis and medial pterygoid muscles and the submandibular gland. The external carotid artery ran along the posterolateral side of the space.
