Superior orbital fissure

Superior orbital fissure. Dr Bahman Rasuli and Assoc Prof Frank Gaillard et al. The superior orbital fissure is the communication between the cavernous sinus and the apex of the orbit. It is straddled by the tendinous ring which is the common origin of the four rectus muscles ( extraocular muscles ) Superior orbital fissure syndrome, also known as Rochon-Duvigneaud's syndrome, is a neurological disorder that results if the superior orbital fissure is fractured. Involvement of the cranial nerves that pass through the superior orbital fissure may lead to diplopia, paralysis of extraocular muscles, exophthalmos, and ptosis The superior orbital fissure is a 22-mm cleft that runs lateral, anterior, and superior from the apex of 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: oculomotor. The superior orbital fissure is a bony cleft found at the orbital apex between the roof and lateral wall. It is a communication between the orbital cavity and middle cranial fossa and is bounded by the greater wing, lesser wing and body of sphenoid .Its dimensions are 22mm in length and 2-8mm in width (narrowest and widest parts) and it is pear-shaped with a wide base nasally on the body of.

  1. In the superior orbital fissure the oculomotor nerve runs very medial, accompanied laterally by the abducent nerve and medially by the nasociliary nerve. 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
  2. The superior orbital fissure (SOF) is a small (3 x 22 mm), but functionally very important, region. The microsurgical anatomy of the SOF was studied on five adult, formalin-fixed cadavers. The vascular structures of three of them were injected with latex. The SOF contains the third, fourth, and sixt

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
  6. The superior orbital fissure is the narrow cleft through which the orbit communicates with the middle cranial fossa. It has the distinction of being the bony opening having the most cranial nerves passing through it. All of the nerves coursing through the cavernous sinus or its walls converge on and pass through the fissure
  7. RESULTS: The artery of the superior orbital fissure was identified in 20 of 54 patients; 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. It anastomosed with the anteromedial branch of the inferolateral trunk at the superior orbital fissure with.

Orbital apex syndrome (OAS) involves cranial neuropathies in association with optic nerve dysfunction. Orbital apex syndrome is symptomatically related to superior orbital fissure syndrome and cavernous sinus syndrome with similar etiologies. The distinction is the precise anatomic involvement of the disease process The term superior orbital fissure syndrome (SOFS) or Rochon-Duvigneaud syndrome is applied to lesions located immediately anterior to the orbital apex, associated with impaired function of the cranial nerves (III, IV, V, and VI) that enter the orbit through the SOF.[7],[8],[9] An orbital apex syndrome (OAS) is a syndrome involving the same.
