Lateral Orbitofrontal Artery, Inferior View

Description

Seen from an inferior perspective, the orbital surface of the frontal lobe is exposed with the lateral orbitofrontal artery coursing anteromedially across the gyrus rectus and adjacent orbital gyri. Its trajectory is shown in relation to neighboring branches of the anterior cerebral artery and middle cerebral artery along the basal frontal cortex, with cortical veins paralleling portions of the arterial tree and draining posteriorly toward the cavernous and sphenoparietal pathways. Yellow-coded cranial nerves track in the same field, so the artery can be appreciated against the optic nerve region and the anterior perforated substance near the proximal anterior circulation. Orientation is clear. Medial and lateral basal frontal landmarks are easy to separate. Clinically, this small cortical branch matters when you are explaining vascular territories on the orbital frontal cortex, an area at risk in anterior circulation aneurysm surgery and basal frontal contusions. During clipping of an anterior communicating artery aneurysm or dissection around the A1 to A2 segments, orbitofrontal branches can be sacrificed inadvertently, and the resulting ischemia may be subtle on exam but evident on postoperative imaging. The inferior view also supports teaching of subfrontal and pterional approaches, where the relationship between the basal frontal arteries, olfactory tract region, and optic apparatus guides safe retraction and dissection. Common uses include neuroanatomy and neurosurgery teaching files, stroke and aneurysm atlases, and figure panels for papers discussing ACA cortical branches, orbitofrontal infarcts, or basal frontal surgical corridors. It also fits well in radiology education when correlating CTA/MRA vascular branching patterns with the orbital gyri and gyrus rectus. Anatomical accuracy verified by SciePro's Medical Advisory Board.
