Lateral Orbitofrontal Artery, Lateral View

Description

Running along the inferior surface of the frontal lobe, the lateral orbitofrontal artery is traced in lateral profile as it courses anteriorly toward the orbital gyri. Its caliber and branching pattern are shown as a small cortical vessel (often an arteriole at the periphery) distributed over the gyrus rectus and lateral orbital gyrus, lying inferior to the frontal pole and anterior to the insular region. Nearby surface landmarks implied by this perspective include the Sylvian fissure laterally and the anterior cranial fossa floor deep to the orbital surface. Fine pial branches spread distally across the orbitofrontal cortex. Small vessel, big implications. Clinically, this artery sits in territory frequently discussed in relation to the anterior cerebral artery and middle cerebral artery cortical branches, and a lateral view helps clarify which orbitofrontal regions are supplied by small anteroinferior frontal vessels rather than deep perforators. That distinction matters when teaching cortical infarct patterns that produce disinhibition, anosmia, or executive dysfunction after an anterior circulation stroke, and when correlating contusions on the orbital surface of the frontal lobe after head trauma with the pial vessels that can be torn. For skull base and anterior cranial fossa approaches, understanding the vessel’s superficial course over the orbital gyri helps anticipate bleeding points during dural elevation near the cribriform plate region. Neuroanatomy faculty can drop this plate directly into lectures on frontal lobe vascular territories, pial arterial networks, and surface anatomy correlations for clinical neurology and neurosurgery modules. It also fits well in stroke education materials, case reports describing orbitofrontal infarcts, and surgical atlases where a quick lateral reference clarifies the relationship between cortical arteries and the inferior frontal surface.
