However beautiful and unique, the complexity of three-dimensional anatomy of the “parasellar space” (PS), formerly known as the “cavernous sinus” (CS), has defied full understanding by generations of surgeons. Only recently, with the advent of visual magnification as provided by the operating microscope, have truly valid descriptions of this area begun to appear. The centuries old idea that the CS is primarily a venous channel similar to the corpora cavernosa of the penis, yet one complicated by the presence of the internal carotid artery (ICA) and nerves III, IV, VI, V1 and V2, is clearly in error. A more accurate concept is that this so-called “sinus” amounts to truly a “space” characterized by an intricate network of venous channels with identifiable walls surrounding the ICA and elements of four cranial nerves.
