fo·ra·men ro·tun·'dum

[TA] an opening in the base of the greater wing of the sphenoid bone, transmitting the maxillary nerve. Synonym(s): round foramen

for·a·men ro·tun·dum

(fōr-ā'mĕn rō-tŭn'dŭm) [TA] An opening in the base of the greater wing of the sphenoid bone, transmitting the maxillary nerve.

foramen rotundum

A round opening in anterior medial edge of the greater wing of the sphenoid bone, just below the superior orbital fissure, through which the maxillary division of the trigeminal nerve (CN V) passes. The foramen rotundum is anterior to the foramen ovale in the middle fossa of the skull. See also: foramen
