THE CONCEPT OF THE CAVERNOUS SINUS AND ITS ANATOMICAL OBSERVATION

Objective To explore the concept of the cavernous sinus and its microanatomy for providing anatomical bases for neurosurgery. Methods Twenty-two adult cadaver heads fixed in 10% methanal were dissected under the operating microscope.Red latex was injected into the artery and blue latex into vein. Results The blue latex is found not be equal in cavernous sinus but be unequal reticular formation which is adjacent with internal carotid artery and can be separated. Conclusion The paper falls in with the view that the cavernous sinus is a venous plexus. It's important for clinic operation to know the detail anatomy of the five walls, cavities, the cranial nerves, and internal carotid artery in cavernous sinus.
