Understanding the optic strut, anterior clinoid process, and adjacent anatomical structures is important for planning a neurosurgical approach to ophthalmic artery aneurysms and tumors involving the anterior cavernous sinus, medial sphenoid wing, and optic canal.

Aug 16, 2021 · The optic strut is a paired bony projection that joins the body of the sphenoid bone with the anterior clinoid process of the lesser wing of the sphenoid bone. It separates the optic canal superomedially from the superior orbital fissure inferolaterally 1 .

Feb 27, 2023 · The posterior root of the ACP is called optic strut (OS)—also known as the “optic pillar” or “sphenoid strut” (3, 4). The OS is an important landmark during the removal of the ACP (i.e., anterior clinoidectomy) and has been colloquially named the “Rosetta Stone” of the paraclinoid region ( 5 ).

Jan 3, 2024 · The sphenoid bone is one of the eight bones that make up the cranium – the superior aspect of the skull that encloses and protects the brain. Its name is derived from the Greek ‘sphenoeides’, to mean wedge-shaped.

Mar 3, 2016 · The anterior (superior) root is thin and flat, and the posterior (inferior) root, referred to as the sphenoid strut, is thick and rounded. The circular opening between the two roots is the optic canal. The greater wings arise from the sides of the body of the sphenoid bone and curve laterally, posteriorly, anteriorly, and superiorly. The ...

The anatomy, radiological appearance, and diagnostic importance of the optic strut are described and five cases presented to illustrate its value in the diagnosis of infraclinoid aneurysms, optic gliomas, and orbital deformities associated with neurofibromatosis.

Dec 2, 2021 · Objective Anatomic variability of the optic strut in location, orientation, and dimensions is relevant in approaching ophthalmic artery aneurysms and tumors of the anterior cavernous sinus, medial sphenoid wing, and optic canal.

The optic strut, the term used by radiologists and neurosurgeons, or the posterior root of the sphenoid bone, as described in anatomy texts, receives only passing notice of its existence. Yet an incr...

The optic strut represents a bony formation that connects the body of sphenoid bone and its lesser wing and separates optic canal from the medial part of the superior orbital fissure. Surgical procedures on cavernous sinus and suprasellar region demand total removal of the optic strut, which if not removed can

May 25, 2021 · The inferior root of the sphenoid’s lesser wing (LSW) is also known as the optic strut (OS). The OS is a bony projection that forms the inferolateral wall of the optic canal (OC), separating it from the superior orbital fissure (SOF) and all its content.
