The Microanatomical Basis for Cavernous Sinus Surgery
The cavernous sinus (CS) is the venous space on either side of the sella turcica. It extends from the superior orbital fissure to the apex of the petrous temporal bone. There have been several reports on direct surgery within the CS. Parkinson (1965) introduced direct surgery within the CS through a transdural opening in the dural wall. We have used a superior approach through the roof of the CS for direct surgery on intracavernous aneurysms. This study evaluates the microanatomical features of the CS that form the basis for surgery through the roof or the lateral wall of the CS.
