FOCAL SUPPRESSION-BURST ON ELECTROCORTICOGRAPHY AFTER TEMPORAL LOBECTOMY

Of 40 patients with cortical resections for epilepsy, three had focal suppression-burst (S-B) on postresection intraoperative electrocortico graphy (ECoG), Eighteen to 24 months later, two patients were seizure- free and one had rare seizures. Follow-up neuropsychological testing a nd MRI did not reveal unexpected postoperative abnormalities. Follow-u p scalp surface EEGs did not show S-B. Although focal S-B on postresec tion ECoG suggests severe localized cortical damage, this pattern near anterior temporal lobectomy resection margins was not associated with postoperative deficits.
