Anatomical Location Of The Cerebral Surface Of The Sphenoid Greater Wing

Description

Sphenoid greater wing, cerebral surface, occupies the lateral floor of the middle cranial fossa and lies lateral to the body of the sphenoid and sella turcica. In this internal cranial view, the broad concave plate sits anterolateral to the petrous part of the temporal bone and posterior to the lesser wing, with its margins contributing to the region around the superior orbital fissure. Foramina within the greater wing, classically the foramina rotundum, ovale, and spinosum, punctuate this surface and orient the viewer to the anterior and lateral limits of the middle cranial fossa. Bony landmarks read at a glance. Clinical work in the skull base often begins by recognizing this exact bony geography, because the foramen spinosum transmits the middle meningeal artery and the nearby foramen ovale and foramen rotundum transmit mandibular (V3) and maxillary (V2) divisions of the trigeminal nerve. Surgeons planning extradural middle fossa approaches, and radiologists localizing skull base fractures on CT, use the greater wing cerebral surface to anticipate where an epidural hematoma may arise from middle meningeal injury or where perineural tumor spread can track along V2 or V3. The fixed perspective and isolated emphasis on the internal sphenoid surface support clean mental mapping between foraminal positions and adjacent cranial sutures, including the sphenoparietal region and the interface with temporal squama. Use this illustration in gross anatomy and neuroanatomy teaching when introducing the middle cranial fossa floor, in neurosurgery or ENT lecture slides on foraminal corridors, or in medical publishing figures on trigeminal neuropathies and skull base fracture patterns.
