"MORPHOMETRIC AND COMPUTER TOMOGRAPHIC STUDY OF FORAMEN OVALE"

Abstract

The foramen ovale is an opening in the greater wing of the sphenoid bone. The foramen ovale is one of two cranial foramina in the greater wing, the other being the foramen spinosum.  The foramen ovale is posterolateral to the foramen rotundum and anteromedial to the foramen spinosum. Posterior and medial to the foramen is the opening for the carotid canal. The following structures pass 
through foramen ovale-mandibular nerve, accessory meningeal artery, lesser petrosal nerve an emissary vein connecting the cavernous sinus with the pterygoid plexus
