The foramen rotundum (plural: foramina rotunda) is located in the middle cranial fossa, inferomedial to the superior orbital fissure at the base of greater wing of the sphenoid bone. Its medial border is formed by lateral wall of sphenoid sinus. It runs downwards and laterally in an oblique path and joins the middle cranial fossa with the pterygopalatine fossa.
It transmits the maxillary branch of trigeminal nerve (V2), artery of foramen rotundum, and emissary veins.
