Video describes anatomy and contents of superior orbital fissure and orbital apex and the mnemonic to remember it. It is bordered superiorly by the lesser wing and inferiorly by the greater wing of the sphenoid bone. 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. Shi x (1), han h, zhao j, zhou c. In the superior orbital fissure the oculomotor nerve runs very medial, accompanied laterally by the abducent nerve and medially by the nasociliary nerve.

The inferior orbital fissure is located at the margin between the lateral wall and the orbital floor. Involvement of the cranial nerves that pass through the superior orbital fissure may lead to diplopia, paralysis of extraocular muscles, exophthalmos, and ptosis. Projection of the fissure into the antrum in waters view can simulate trabeculation of the sinus or fracture of the inferior orbital rim. ta a cleft between the greater and the lesser wings of the sphenoid establishing a channel of communication between the middle cranial fossa and the orbit, through which pass the oculomotor and trochlear nerves, the ophthalmic division of the trigeminal nerve, the abducens nerve, and the superior or combined.

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. It is composed of fat, small veins, and nerve fibres associated with the pterygopalatine ganglion (ppg) (weninger and prahmas 2000 ). The superior orbital fissure is the narrow cleft through which the orbit communicates with the middle cranial fossa. Other structures passing through it are superior & inferior ophthalmic veins, meningeal branch of the lacrimal artery and anastomotic branch of middle meningeal artery which anastomoses with the recurrent branch of lacrimal artery. The most common orbital component arises from tumor growth through the superior orbital fissure but optic canal extension is occasionally seen. The artery of the superior orbital fissure was identified in 20 of 54 patients;
The superior orbital fissure forms the largest communication between the orbit and intracranial structures and therefore forms a conduit for infectious or neoplastic processes between the orbital apex and the cavernous sinus.
The cavernous sinus fills the posterior margin and the orbital contents fill the anterior margin of the fissure. Mnemonic for all structures passing through the superior orbital fissure (superior to inferior) include: This fissure divides the greater as well as lesser wings of the sphenoid and is located in the middle of the optic foramen and the foramen rotundum. It arose at the pterygopalatine segment of the maxillary artery, either singly or from a common trunk with the artery of the foramen rotundum, and ran upward to reach the superior orbital fissure. Associated orbital enlargement can lead to diagnostic confusion in the investigation of headache, especially if the superior orbital fissures show marked asymmetry suggesting erosion. The superior orbital fissure is a narrow cleft connecting the middle cranial fossa and the orbit. This fissure, which separates the greater and lesser wings of the sphenoid and lies between the optic foramen and the foramen rotundum, provides passage to the three motor nerves to the extraocular muscles of the orbit: About press copyright contact us creators advertise developers terms privacy policy & safety how youtube works test new features press copyright contact us creators. The sof contains the third, fourth, and sixt … It is bordered superiorly by the lesser wing and inferiorly by the greater wing of the sphenoid bone. Structures passing through superior orbita. The superior orbital fissure is a bony cleft found at the orbital apex between the roof and lateral wall. The superior orbital fissure is the largest opening that connects the orbit with the middle cranial fossa.
This fissure, which separates the greater and lesser wings of the sphenoid and lies between the optic foramen and the foramen rotundum, provides passage to the three motor nerves to the extraocular muscles of the orbit: Orbital apex syndrome (oas) involves cranial neuropathies in association with optic nerve dysfunction. It arose at the pterygopalatine segment of the maxillary artery, either singly or from a common trunk with the artery of the foramen rotundum, and ran upward to reach the superior orbital fissure. Long fissures seem to store only nerves, instead of arteries, including ophthalmic veins. Superior division of oculomotor nerve.
Lateral Aspect Of The Left Cavernous Sinus Superior Orbital Fissure And Orbit Neuroanatomy The Neurosurgical Atlas from assets.neurosurgicalatlas.com The superior orbital fissure is a bony cleft found at the orbital apex between the roof and lateral wall. The nerves passing through superior orbital fissure are (from top to bottom) : The mnemonic helps to recall all the nerves passing through superior orbital fissure. The superior orbital fissure is a cleft that opens anteriorly into the orbit, and enables communication between the cavernous sinus and the apex of the orbit. The most common orbital component arises from tumor growth through the superior orbital fissure but optic canal extension is occasionally seen. The superior orbital fissure is the narrow cleft through which the orbit communicates with the middle cranial fossa. It anastomosed with the anteromedial branch of the inferolateral trunk at the superior orbital fissure with. The microsurgical anatomy of the superior orbital fissure was examined in cadaver specimens.
Mnemonic for all structures passing through the superior orbital fissure (superior to inferior) include:
The pterygopalatine fossa presents an extension within the superior orbital fissure ( sof ), inferior to the lateral sellar compartment and muller's muscle. The superior orbital fissure is the largest opening that connects the orbit with the middle cranial fossa. Because of this, the emphasis of the technique is on the medial aspect of the fissure, while turning the patient's head to the side of the fissure being treated. The nerves passing through superior orbital fissure are (from top to bottom) : Video describes anatomy and contents of superior orbital fissure and orbital apex and the mnemonic to remember it. This fissure divides the greater as well as lesser wings of the sphenoid and is located in the middle of the optic foramen and the foramen rotundum. The superior orbital fissure is a cleft that opens anteriorly into the orbit, and enables communication between the cavernous sinus and the apex of the orbit. The vascular structures of three of them were injected with latex. The superior orbital fissure is the narrow cleft through which the orbit communicates with the middle cranial fossa. Mnemonic for all structures passing through the superior orbital fissure (superior to inferior) include: The superior orbital fissure is the communication between the cavernous sinus and the apex of the orbit.

Projection of the fissure into the antrum in waters view can simulate trabeculation of the sinus or fracture of the inferior orbital rim.
It is straddled by the tendinous ring which is the common origin of the four rectus muscles ( extraocular muscles ). Microsurgical anatomy of the superior orbital fissure. The cavernous sinus fills the posterior margin and the orbital contents fill the anterior margin of the fissure.
