The superior orbital fissure is a foramen in the skull, although strictly it is more of a cleft, lying between the lesser and greater wings of the sphenoid bone.
The main features of the lesser wing are the optic canal, the anterior clinoid process, and the superior orbital fissure.

Oculomotor nerve

superior and inferior divisions of oculomotor nerve (III)
It enters the orbit via the superior orbital fissure and innervates extrinsic eye muscles that enable most movements of the eye and that raise the eyelid.

Orbit (anatomy)

orbitorbitseye socket
A number of important anatomical structures pass through the fissure, and these can be damaged in orbital trauma, particularly blowout fractures through the floor of the orbit into the maxillary sinus.
There is a supraorbital foramen, an infraorbital foramen, a superior orbital fissure, an inferior orbital fissure and the optic canal, each of which contains structures that are crucial to normal eye functioning.

Ophthalmic nerve

ophthalmicophthalmic divisionophthalmic branch
lacrimal, frontal and nasociliary branches of ophthalmic (V 1 ).
The frontal branch passes through the orbit superiorly, then reenters the frontal bone briefly before exiting above the orbit through the superior orbital fissure and the supraorbital notch to provide sensory innervation for the skin of the forehead and scalp.

Frontal nerve

frontal
lacrimal, frontal and nasociliary branches of ophthalmic (V 1 ). Lateral part transmits: superior ophthalmic vein, lacrimal nerve, frontal nerve, trochlear nerve (CN IV), recurrent meningeal branch of lacrimal artery (anastomotic branch of lacrimal artery with the middle meningeal artery)
It enters the orbit through the superior orbital fissure, not running within the tendinous ring, and runs forward between the levator palpebrae superioris and the periosteum.

Lacrimal nerve

lacrimal, frontal and nasociliary branches of ophthalmic (V 1 ). Lateral part transmits: superior ophthalmic vein, lacrimal nerve, frontal nerve, trochlear nerve (CN IV), recurrent meningeal branch of lacrimal artery (anastomotic branch of lacrimal artery with the middle meningeal artery)
It passes forward in a separate tube of dura mater, and enters the orbit through the narrowest part of the superior orbital fissure.

Greater wing of sphenoid bone

alisphenoidgreat winggreat wing of the sphenoid
The superior orbital fissure is a foramen in the skull, although strictly it is more of a cleft, lying between the lesser and greater wings of the sphenoid bone.
Its medial sharp margin forms the lower boundary of the superior orbital fissure and has projecting from about its center a little tubercle that gives attachment to the inferior head of the lateral rectus muscle; at the upper part of this margin is a notch for the transmission of a recurrent branch of the lacrimal artery.

Finally, it enters the orbit through the superior orbital fissure and innervates the superior oblique muscle.

Cavernous sinus

This presentation indicates either compression of structures in the superior orbital fissure or the cavernous sinus.
Anteriorly: superior orbital fissure.

Superior ophthalmic vein

Lateral part transmits: superior ophthalmic vein, lacrimal nerve, frontal nerve, trochlear nerve (CN IV), recurrent meningeal branch of lacrimal artery (anastomotic branch of lacrimal artery with the middle meningeal artery)
Forming a short single trunk, it passes between the two heads of the Rectus lateralis and through the medial part of the superior orbital fissure, and ends in the cavernous sinus.

Inferior orbital fissure

4) Orbital branches pass through the superior orbital fissure or through separate canals in the great wing of the sphenoid, to anastomose with the lacrimal or other branches of the ophthalmic artery.

The superior orbital fissure is a foramen in the skull, although strictly it is more of a cleft, lying between the lesser and greater wings of the sphenoid bone.

Inferior ophthalmic vein

inferiorinferior ophthalmicinferior ophthalmic veins
Medial part transmits: Inferior ophthalmic veins and sympathetic nerves arising from the plexus that accompanies the internal carotid artery
One of these passes through the inferior orbital fissure and joins the pterygoid venous plexus, while the other enters the cranium through the superior orbital fissure and ends in the cavernous sinus, either by a separate opening, or more frequently in common with the superior ophthalmic vein.

Lacrimal artery

Lateral part transmits: superior ophthalmic vein, lacrimal nerve, frontal nerve, trochlear nerve (CN IV), recurrent meningeal branch of lacrimal artery (anastomotic branch of lacrimal artery with the middle meningeal artery)
A recurrent branch passes backward through the lateral part of the superior orbital fissure to the dura mater, and anastomoses with a branch of the middle meningeal artery.
