Fox today's instrume nts, the ne u rosu rgeon finds that the pterional approach to skull-base lesions is a more natural and easier procedure than earl ier-day operations. Yet, there is a fascinating hiSlOrica l background over the last years, that form s the basis o f the present-day pterional approach. There are several pioneers who made mo numental contributions to the development of this access to deep-seated cran ial-base lesions.
