The foramen rotundum is a circular opening in the base of the greater wing of the sphenoid bone, found posterior to the medial end of the superior orbital fissure. This foramen allows passage for the maxillary nerve, the second branch of the trigeminal nerve (CN V).
The foramen rotundum runs an inferior and lateral course and connects the middle cranial fossa with the pterygopalatine fossa.
