Temporal Surface Of The Sphenoid's Greater Wing, Anterior View

Description

Sphenoid bone anatomy dominates the frame, focusing on the temporal surface of the greater wing as it faces laterally and slightly anteriorly in an anterior view. The smooth concavity sits inferior to the frontal bone and anterior to the squamous part of the temporal bone, contributing to the medial wall and floor region of the temporal fossa. Along the inferior margin, the infratemporal crest forms a sharp ridge separating the temporal surface above from the infratemporal surface below, a reliable landmark when orienting the greater wing in the intact skull. Fracture lines through the greater wing commonly involve the pterion region, where the thin temporal fossa wall overlies the anterior branch of the middle meningeal artery, so small bony disruptions can correlate with epidural hematoma risk and urgent neurosurgical decision-making. For skull base teaching, the fixed anterior perspective clarifies how the temporal surface participates in the temporal fossa without conflating it with the foramina of the infratemporal surface (foramen ovale and foramen spinosum) that lie inferior to the crest and are approached from different surgical corridors. Orientation is unambiguous. The concavity reads as a muscle bed rather than a passageway. Use this illustration in head and neck anatomy curricula when introducing the temporal fossa, temporalis muscle origin, and the bony landmarks used to localize the pterional approach in neurosurgery and craniofacial surgery atlases. It also suits figure panels in radiology teaching files that correlate calvarial fractures with sphenoid wing involvement on CT. Anatomical accuracy verified by SciePro's Medical Advisory Board.
