Abstract

In order to predict the possibility of complete resection of intracranial meningioma according to anatomical sites; the authors have analyzed 36 surgical cases of intracranial meningiomas retrospectively from June; 1982 to May; 1988. The distribution of the sites in the intracranial meningiomas were; convexity(27.8r/r); parasagittal and falx(25 %); middle cranial fossa(22.2%); anterior cranial fossa(13.9%}’ posterior cranial fossa(5.6%); intraventricular(5.6 ^f) area. Convexity and intraventricular meningiomas were removed totally in all of 12 cases and parasagittal and falx meningiomas were removed totally in 8 cases and subtotally in 1 case. Anterior fossa were removed totally in 3 cases; subtotally in 1 case and partially in 1 case. Middle fossa were removed totally in 5 cases; subtotally in 2 cases and partially in 1 case. Posterior fossa were removed totally in 1 case and partially in 1 case. Therefore meningiomas that removed totally and subtotally were 33 casestQl.B^) and partially in 3 cases(8.4%). The outcome at discharge was excellent in 20 cases(55.6%); good in 10 cases(27.8%); fair group in 4 cases(ll.l °/(). The mortality rate was 5.6%(2 cases). From this study; we concluded that intracranial meningiomas could remove totally; which were located in convexity; parasagittal and falx; orbit; olfactory groove; lateral sphenoidal ridge; pyramid; intraventricle and posterior convexity; but were difficult to total removal in medial sphenoidal ridge; cavernous sinus and falcotentorial junction.
