RESUMO
Since October, 1989, the authors underwent operations for 20 patients of medically intractable epilepsy. Eight patients with temporal lobe epilepsy were treated by temporal lobectomy. Four patients with extratemporal focus of seizure were treated with extratemporal cortisectomy, Eight patients with multiple types of seizure were treated with callosotomy. The presurgical evaluations of epileptic seizures were very important. The presurgical evaluations were standard EEG, CCTV-EEC morning, neuroimaging, neuropsychological test, Wade test and invasive study with intracranial electrodes. There were no serious complications after operation. The authors concluded that epilepsy surgery seemed to be safe and helpful method for the treatment of medically intractable epilepsy.
