Abstract

The petroclival meningiomas belong to the meningioma of the Fossa cranii posterior and constitute only 1% of them. Since they belong to the group of the meningioma, they have their origin in the hyperplastic procedures of the meninges in the arachnoidal cap cells of the pacchionian granulations.They arise preferentially in the middle age and show in the reference to their frequency a summit with patients in the fifth life decade. In addition women are twice as frequently affected as men.Meningiomas grow slowly and displacing and can achieve partially very large extents. The symptoms caused by them can be explained by the close neighbourhood relations with the nerves III-XII, brain stem and brain-supplying veselles.As therapy of the choice the micro-surgical extirpation is to be called. Both the selection of the surgical entrance and the decision, whether a partial or a complete resection is accomplished, are multifactorially conditioned.As supporting therapy for the treatment of remaining tumour parts or recurrence the Gamma-Knife treatment is used as therapy of the choice.During the evaluation of the recurrence problem with the petroclival meningiomas connections between age, sex, tumour localization, the surgical resection grade, histological type and recurrence appearance develop.The aim of this work was to evaluate the growth behaviour of petroclival meningiomas after operational interference, is it in form of a partial or complete resection in long-term process. In this connection it has to be shown whether remainder or recurrence leads to morbidity. These two points should help to evaluate how aggressively petroclival meningiomas should be treated and whether aggressive operational removing is justified regarding these results.
