Abstract
This article presents the surgical results in a series of 16 petrocliv al meningiomas operated on from 1984-1990. Tumors with marked infiltra tion of the cavernous sinus, which belong to the category of spheno-pe tro-clival meningiomas, were excluded. The 16 petroclival meningiomas were all surgically treated using the combined transmastoid temporosub occipital approach that offers a number of possible variants: retrosig moidal, with or without recision of the sinus; presigmoidal retro-, or translabyrinthine. The choice of one or another of these variants dep ends on certain clinical (preoperative hearing status) and anatomic (s ize and extension, central or lateral, of the tumor; patency of the tr ansverse sinuses; size and position, more or less anterior, of the sig moid sinus; position, more or less high, of the jugular bulb) factors. The principle indications for each of these approaches are given with particular emphasis on their relative advantages and limitations.
