Bringing Polemic Issues with Inchoate Guidelines into Sharper Focus

The expert says:
This is a typical Zone I low-grade insular glioma that should be approached with an awake language mapping craniotomy, followed by resection through either a transcortical or transsylvian approach (or both combined depending upon the results of the mapping). The expected extent of resection should be at least 85-90 percent or better with anticipated morbidity of less than two percent, using both cortical and subcortical mapping.
