 note = {It is an important procedure to peel off the dura propria from the lateral wall ofthe cavernous sinus in skull base surgeries. Extradural temporopolar ap-proach (EDTA) with this procedure makes it possible to preserve venous return from superficial middle cerebral vein (SMCV). We evaluated the variation of venous system with preoperative angiography in 24 cases and in 9 of 24 cases checked post-operative angiography also. EDTA did not make venous return from SMCV worse in any cases. Preoperative venous route from SMCV occluded in most cases ofCavernous sinus type (CS type) in which SMCV join cavernous sinus directly or through spheno-parietal sinus. But no cases of CS type had venous infarction. We think it is most important to preserve intradural collate-ral venous route as much as possible in EDTA.},
