Importance
If at all present, the sphenoidal emissary foramen gives passage to a small vein (vein of Vesalius) that connects the pterygoid plexus with the cavernous sinus. The importance of this passage lies in the fact that an infected thrombus from an extracranial source may reach the cavernous sinus. The mean area of the foramen is small, which may suggest that it plays a minor role in the dynamics of blood circulation in the venous system of the head.

Famous quotes containing the word importance:
“Coming together again after a long day apart can be an experience where joy, relief, anger, and fatigue are all present in different degrees both for the parent and for the child.
