Position of the foramen rotundum (arrows) as seen from the middle fossa

This foramen rotundum (lat. For "round hole") is an opening in the skull in the region of the sphenoid bone , the middle cranial fossa ( middle cranial fossa ) with the pterygopalatine pit ( pterygopalatine fossa connects). In the adult human, it is about 3.5 mm. The foramen rotundum is the point of passage for the maxillary nerve , a branch of the cranial fifth nerve .

In ruminants and pigs , the rotundum foramen is fused with the orbital fissure to form the orbitorotundum foramen .
