Operations on gliomas involving speech centres.

Abstract

One hundred patients with gliomas of the dominant hemisphere, who survived for more than one year after operation, have been analysed. In all of them radical tumour removal had been attempted. Already preoperatively 58 of them had signs of speech deficit. Postoperatively 65% improved and only 15% deteriorated with regard to their speech function. Therefore it seems not to be justified to deny operative tumour removal to patients with gliomas located within or near the speech areas.
