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:
“Whoever deliberately attempts to insure confidentiality with another person is usually in doubt as to whether he inspires that person’s confidence in him. One who is sure that he inspires confidence attaches little importance to confidentiality.”
—Friedrich Nietzsche (1844–1900)
““I’m sure you’ve often wished there was an after-life.” Of course I had, I told him. Everybody has that wish at times. But that had no more importance than wishing to be rich, or to swim very fast, or to have a better-shaped mouth.”
—Albert Camus (1913–1960)
“The importance of a lost romantic vision should not be underestimated. In such a vision is power as well as joy. In it is meaning. Life is flat, barren, zestless, if one can find one’s lost vision nowhere.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 1, ch. 19 (1962)
