“…Venous bleeding from the pterygoid plexus 26 may be copious and should be anticipated when planning any surgery involving the infratemporal fossa and UPPS. 14,27 The extent of the pterygoid plexus is variable, but the deep pterygoid plexus is always evident at the medial aspect of lateral pterygoid muscle.…”

Background Lesions of the upper parapharyngeal space (UPPS) present a surgical challenge. The objective of this study was to ascertain the feasibility of a novel technique of modified transpterygoid approach to the UPPS. Methods Six fresh cadaveric specimens (12 sides) were dissected, developing a technique that includes en bloc mobilization of the lateral pterygoid plate and muscle to access the UPPS. Results Following an endoscopic Denker's approach and the removal of posterolateral wall of the antrum, the lateral pterygoid plate was detached from the pterygoid process. Subsequently, the lateral pterygoid plate and muscle were displaced laterally as a unit, allowing the identification of the posterior trunk of V3 and the fat in prestyloid compartment. Dissecting off the styloid aponeurosis affords entering the poststyloid UPPS exposing the internal carotid artery, internal jugular vein, and cranial nerves IX to XII. Conclusion This novel modification of the endonasal transpterygoid approach offers a viable alternative for access to the UPPS.

A methyl methacrylate casting technique was used to make detailed casts of the intracerebral venous system of four human cadaver specimens. Seven of the eight petrous apices studied were diploeic (n = 5), or pneumatic (n = 2) and had venules coursing in the anterior petrous apex. These venules form conduits connecting the cavernous to the inferior petrosal sinus or the jugular bulb and have not been previously described. In addition to the air cell system of the petrous apex, these venules may represent pathways for the spread of infection and the development of petrous apicitis, Gradenigo's syndrome, and the rare otogenic cavernous sinus thrombophlebitis. Their presence also may help explain the location of cholesterol granulomas, which afflict this area of the skull base.

“…The deep (periosteal) branch of the occipital artery supplies the pericranial flap [28]. The occipital artery runs over the superior oblique capitis muscle and pierces the occipitofrontal muscle aponeurosis in a variable location within the lateral two-thirds of the supreme occipital line.…”
