superior orbital fissure

It can be used to divide the regions of the superior orbital fissure.

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

It then enters the orbit through the superior orbital fissure and innervates the lateral rectus muscle of the eye.

The main features of the lesser wing are the optic canal, the anterior clinoid process, and the superior orbital fissure.

The inferior surface forms the back part of the roof of the orbit, and the upper boundary of the superior orbital fissure.

It then divides into two branches, which enter the orbit through the superior orbital fissure, between the two heads of the lateral rectus.

Behind the medial end of the superior orbital fissure is the foramen rotundum, for the passage of the maxillary nerve.

The oculomotor nerve passes through the lateral wall of the cavernous sinus and enters the orbit through the superior orbital fissure.

It passes forward in a separate tube of dura mater, and enters the orbit through the narrowest part of the superior orbital fissure.

Tolosa-Hunt syndrome is a variant of orbital pseudotumor in which there is extension into the cavernous sinus through the superior orbital fissure.

Involvement of the cranial nerves that pass through the superior orbital fissure may lead to diplopia, paralysis of extraocular motions, exophthalmos, and ptosis.

It enters the orbit through the superior orbital fissure, not running within the tendinous ring, and runs forward between the Levator palpebræ superioris and the periosteum.

These nerves, with the exception of CN V, pass through the cavernous sinus to enter the orbital apex through the superior orbital fissure.

One can zoom in on the superventricular crest of the right ventricle of the heart, and fly through an eyeball to the superior orbital fissure of a skull.

The ophthalmic, maxillary and mandibular branches leave the skull through three separate foramina: the superior orbital fissure, the foramen rotundum and the foramen ovale.

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.

Behind, it is united with the dura mater by processes which pass through the optic foramen and superior orbital fissure, and with the sheath of the optic nerve.

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.

The exact cause of Tolosa-Hunt syndrome is not known, but the disorder is thought to be associated with inflammation of the areas behind the eyes (cavernous sinus and superior orbital fissure).

Jarrahy R, Cha ST, Shahinian HK: Retained foreign body in the orbit and cavernous sinus with delayed presentation of superior orbital fissure syndrome.

Below the medial end of the superior orbital fissure is a grooved surface, which forms the posterior wall of the pterygopalatine fossa, and is pierced by the foramen rotundum.

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.

Superior orbital fissure syndrome, also known as Rochon-Duvigneaud's syndrome, is a neurological disorder that results if the superior orbital fissure is fractured.

In 1896 he described a neurological disorder characterized by exophthalmos, diplopia, and anaesthesia in regions innervated by the trigeminal nerve, occurring with a traumatic collapse of the superior orbital fissure.

The apex lies near the medial end of superior orbital fissure and contains the optic canal (containing the optic nerve and ophthalmic artery), which communicates with middle cranial fossa.
