Inferior orbital fissure

from Wikipedia, the free encyclopedia

The inferior orbital fissure is an approximately 30 mm long and up to 5 mm wide bony gap between the large wing of the sphenoid bone and the floor of the eye socket in the human skull . It opens the eye socket towards the palatal fossa ( fossa pterygopalatina ) and the temporal fossa . The following structures run through the inferior orbital fissure:

The inferior orbital fissure is covered like a mesh by the smooth muscles of the orbitalis muscle . This can compress the orbital contents during contraction or give way if it is pushed backwards during contraction of the eyelid and eye muscles and the intraorbital pressure increases.
