Tentorial dural arteriovenous fistulas (AVFs) are uncommon lesions usually treated surgically using a subtemporal exposure with division of the tentorium. This exposure requires significant retraction of the temporal lobe and has the possibility of significant arterialized venous bleeding if a draining vein is accidentally cut during division of the tentorium. Skull base surgical techniques may provide alternate approaches for the surgical treatment of tentorial dural AVFs. ⋯ Tentorial dural AVFs can be safely treated with interruption of the venous drainage. The exposure can be enhanced with a petrosal approach, decreasing the possibility of uncontrolled bleeding during the procedure.
