Detailed anatomical diagram of the parapharyngeal space showing: inverted pyramid shape with apex at hyoid bone and base at skull base, labeled boundaries (superior: sphenoid and temporal bones, inferior: hyoid, anterior: pterygomandibular raphe, medial: superior constrictor muscle, lateral: medial pterygoid, ramus of mandible, deep lobe of parotid, posterior: prevertebral fascia), the styloid process dividing space into prestyloid and poststyloid compartments, aponeurosis of Zuckerkandl and Testut fascia, contents of each compartment clearly labeled, carotid sheath, cranial nerves IX-XII, sympathetic chain, stylomandibular tunnel, retropharyngeal space relation. Medical textbook style, black and white line diagram with labels

Flowchart showing parapharyngeal space compartments and contents: top box "PARAPHARYNGEAL SPACE (Inverted Pyramid)", divides into two branches: left branch "PRE-STYLOID COMPARTMENT (Anterior)" with sub-items: fat and areolar tissue, deep lobe of parotid, ascending pharyngeal artery, internal maxillary artery, inferior alveolar nerve, lingual nerve, auriculotemporal nerve, tensor veli palatini nerve, ectopic salivary gland tissue, lymphatics; right branch "POST-STYLOID COMPARTMENT (Posterior/Retrostyloid)" with sub-items: internal carotid artery, internal jugular vein, CN IX glossopharyngeal, CN X vagus, CN XI accessory, CN XII hypoglossal, cervical sympathetic chain, lymph nodes, glomus bodies. Bottom section shows communications: connects to retropharyngeal space, masticator space, submandibular space, carotid space, parotid space. Clean medical flowchart with blue and orange color coding
