Compartmentalization of the human cephalic parapharyngeal space: a scoping review.
Article in Surgical and radiologic anatomy : SRA, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe existing literature tends to describe the division of the cephalic parapharyngeal space into its prestyloid and poststyloid compartments by relying on either the tensor-vascular-styloid fascia, the styloid diaphragm, or one of many other musculofascial structures, while disregarding the existence of the rest. This scoping review is aimed at integrating these widely differing anatomical descriptions to achieve a more complete understanding of this complex region.
methodsIn accordance with the PRISMA-ScR guidelines, online databases were used to identify scientific publications that described the compartmentalization of the cephalic parapharyngeal space. 202 studies were deemed eligible for review and were subsequently categorized according to what anatomical structure they considered to compartmentalize the region.
resultsThe anatomical structures most frequently considered to be the dividing boundary between the prestyloid and poststyloid compartments were the tensor-vascular-styloid fascia (in 43.6% of reviewed studies) and the styloid diaphragm (in 30.7%), followed by the styloid process on its own (7.4%), the styloid muscles (5.9%), fascial condensations (4%), the styloid process and the tensor veli palatini muscle (2%), the stylopharyngeal aponeurosis (1%), the stylohyoid ligament (0.5%), and an imaginary plane (0.5%).
conclusionWe propose a more comprehensive description of the region considering the coexisting musculofascial structures that subdivide it, with the styloid diaphragm coronally dividing the cephalic parapharyngeal space into poststyloid and prestyloid compartments, and the latter being further divided by the stylomandibular membrane and the tensor-vascular-styloid fascia into the parotid, paramasticatory, and paratonsillar spaces.
