The Anatomy Of The Infratemporal Surface Of The Greater Wing Of The Sphenoid

Description

Across the posterior roof of the infratemporal fossa, the animation tracks along the infratemporal surface of the greater wing of the sphenoid as it runs lateral to the pterygoid plates and inferior to the temporal fossa. Anteriorly it approaches the posterior surface of the maxilla and the inferior orbital fissure, while posteriorly it leads toward the spine of the sphenoid near the mandibular fossa of the temporal bone. Medially, the contour resolves into the foramen ovale and foramen spinosum with the intervening sphenoid ridge and adjacent pterygoid region, and laterally it meets the zygomatic bone at the lateral orbital margin. Bony landmarks come into view sequentially as the camera glides and rotates, clarifying how this “flat” skull base area is actually subtly concave and topographically organized. Orientation to this surface matters in skull base teaching because it anchors the corridor used in infratemporal fossa and lateral transzygomatic approaches, where surgeons work between the posterior maxilla, the pterygoid process, and the mandibular ramus. The foramen ovale and foramen spinosum provide fixed waypoints for V3 and the middle meningeal artery, and their relationship to the lateral pterygoid region helps explain patterns of perineural tumor spread and why middle meningeal artery injury is a concern in adjacent cranial base fractures. Motion helps. Seeing the surface swept from anterior to posterior makes the foramina and ridges easier to map than in a single still. Use this animation in head and neck anatomy courses, dental and maxillofacial training modules, and neurosurgical or ENT skull base atlases that need clean spatial relationships between the sphenoid, maxilla, zygoma, and temporal bone. It also fits radiology education when correlating CT bone windows with the expected position of foramen ovale and foramen spinosum. Anatomical accuracy verified by SciePro's Medical Advisory Board.
