Midline lesion at the base of skull have been considered in the past to be inoperable, partially respectable, and even when respectable, unpleasant difficult. According for the above has been the poor visulization of minimal surgical exposure, copious bleeding and lack of adequate fluoroscopic depth monitoring. These built-in difficulties may prove to be a fertile ground for microsurgery. Presently the use of the surgical dissecting microscope, portable image intensifiers and specifically designed microinstruments has enabled to permit approach of clival area for removal of the clival tumor.
