inferior orbital fissure connects what spaces

The inferior orbital fissure lies inferior and lateral to the ocular globe at the lateral wall of the maxillary sinus. It is not as important in function, though it does contain a few branches of the maxillary nerve and the infraorbital artery and vein.

Through the inferior orbital fissure the orbit communicates with the temporal, infratemporal, and pterygopalatine fossae. The fissure transmits the maxillary nerve and its zygomatic branch, the infraorbital vessels, the ascending branches from the sphenopalatine ganglion, and a vein which connects the inferior ophthalmic vein with the pterygoid venous plexus.

Anteriorly, the pterygopalatine fossa opens into the floor of the orbit through the inferior orbital fissure. Laterally , it communicates with the infratemporal fossa through the pterygomaxillary fissure , which can be thought of as an open doorway framed by the margin of the pterygoid process of the sphenoid and the tuberosity of the maxilla.

The maxillary nerve leaves the skull through the foramen rotundum and arrives in the superior part of the pterygopalatine fossa (Fig. 16.1). It enters the inferior orbital fissure, crosses the infra-orbital groove, and appears on the face through the infra-orbital foramen.
