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 electrocorticography (ECoG). Eighteen to 24 months later, two patients were seizure-free and one had rare seizures. Follow-up neuropsychological testing and MRI did not reveal unexpected postoperative abnormalities. Follow-up scalp surface EEGs did not show S-B. Although S-B on postresection ECoG suggests severe localized cortical damage, this pattern near anterior temporal lobectomy resection margins was not associated with postoperative deficits.
