The surgical approach consists of a cervicoparotid approach, which can be combined with an infratemporal fossa approach type A. This approach permits removal of the tumor from the skull base with optimal vision of the skull base and of the vertical and horizontal portions of the internal carotid artery. The intracranial intradural extension can be removed in one stage even for D2 tumors because it is usually not attached to the surrounding structures and is lateralized by the CSF pressure as long as the arachnoid remains intact.
