[Relation of surgical results and proposed skull base meningioma grading system: analysis of clinical series with 42 patients].
Anatomical localisation of skull base meningioma link, their growth and relations with neurovascular structures reduce possibility for radical operation, and offten request additional preoperative or postoperative radiotherapy. We compared personal results of extent surgical resection and skull base meningioma treating outcome with predispose factors scale for surgical radicality and postoperative outcome. We present 42 patients, who were operated in Institute of neurosurgery CCS during the period from 2004 to 2006.


RESULTS
Radical resection was possible in 29 cases, and in 13 cases reduction of tumor mass has been performed. Statistical significant predispose factor for radical resection were: absance of preoperative radiotherapy, intact functions of n.III, n.VI, tumor borders inside one skull base fossa and outside of magistral blood vessels. Karnofsky index at the end of following period statistical significant higher in patients with radical resection of skull base meningeioma. Preoperative radiological finding is singificant guide in planning of therapeutic protocol for skull base meningioma. Growth of tumor and relation with neurovascular structures restrict extent of resection and often request additional postoperative radiotherapy or reoperation.
