[edit on Wikidata]

The inferior orbital fissure is a gap between the greater wing of sphenoid bone, and the maxilla. It connects the orbit (anteriorly) with the infratemporal fossa and pterygopalatine fossa (posteriorly).[1]: 397 

Anatomy

The medial end of the inferior orbital fissure diverges laterally from the medial end of the superior orbital fissure. It is situated between the lateral wall of the orbit and the floor of the orbit.[1]: 397 

Contents

The fissure gives passage to multiple structures, including:
