A surgical approach to the skull base is described. It allows excellent exposure of the cranial base with minimal brain retraction. Deep lesions can be handled via subfrontal, transsylvian, or subtemporal routes during the same operation. This approach is most suitable for large lesions in the suprasellar, parasellar, and retrosellar areas and for those that extend into the cavernous sinus, along the tentorial notch, or into the orbit. After the single bone flap is replaced, there is little or no functional, anatomical, or cosmetic deficit. Our experience in 16 cases and suggestion for the use of this approach are presented.
