31ª SEMANA CIENTÍFICA DO HOSPITAL DE CLÍNICAS DE PORTO ALEGRE Rev HCPA 2011; 31 (Supl.)                                                                                         176   were measured. Each cadaveric head was placed in a Sugita head-holder and a cranioorbitozygomatic approach (COZ) and Total clivectomy approach were performed. Seven cases are presented to illustrate this anatomy. Clival chordoma with CS extension medial to the internal carotid artery (anterior Clivectomy approach) , clival neuroblastoma displacing the medial wall of the CS  (endonasal endoscopic approach), trigeminal schwannoma (COZ) Adenocarcinoma of the CS with temporal lobe and pterygopalatine fossa extension (COZ with middle fossa peeling followed by infratemporal and pterygopalatine fossa exploration) Cavernous sinus meningeoma (COZ),  Sphenopetroclival meningeoma ( petrosal approach) and tubercullum sellar meningeoma with lateral wall CS extension (COZ). Results: The complex anatomy and CS approaches are presented. Except for the partial oculomotor nerve palsy in the patient with cavernous sinus meningeoma, there was no postoperative neurological deficit. Complete resection (at least more than 90% of the tumoral component) was achieved in all cases. Conclusion: Each pathological process has its intrinsic peculiarities and must be considered before or during the surgery. This kind of anatomical study using different approaches allows us variable views of the same area, getting a really three-dimensional knowledge.

Methods: Eighteen CS of five cadaveric heads and four skull base fixed in formalin were dissected using 3X to 40X magnification of the surgical microscope. The heads and skull bases were injected with colored silicone and the sides and area of the triangles
