title: [The characteristics of the surgical treatment of basal meningiomas with supra-subtentorial spread].
abstract: The results of surgical treatment of 63 patients with basal meningiomas with supra-subtentorial spread were analyzed. The study has shown the effectiveness of one-stage tumor removal via supra-transtentorial approach with skull base bones resection. It is recommended to estimate an extent of operation on the basis of intraoperative assessment of biological behavior of the tumor, including interrelationship of tumor capsule and brainstem pia mater. Mortality rate was decreased from 23.8% to 11.1% following introduction of these principles.
