The document discusses the anatomy and surgical approaches related to the cavernous sinus. It describes the osseous relationships and triangles in the region, as well as different craniotomy techniques like pterional craniotomy, one-piece orbitozygomatic craniotomy, and two/three-piece orbitozygomatic craniotomy that provide intradural access. The presentation provides an overview of dissection, landmarks, and technical considerations for microsurgery of the cavernous sinus.
