P.013 Stereo-encephalographic presurgical evaluation of temporal lobe epilepsy

Background: Drug resistant epilepsy is present in nearly 30% of patients. Resection the epileptogenic zone has been found to be most effective achieving seizure freedom. The study temporal lobe for surgical treatment extensive and complex. It involves a multidisciplinary team decision-making with initial non-invasive studies (Phase I), providing 70% required information elaborate hypothesis plans. Select cases more complexity involving bilateral clinical or electrographic manifestations, have contradicting may involve deeper structures as part zone. Methods: A review literature was done key terms such as: “temporal epilepsy”and “SEEG”and “intracranial EEG”, “epilepsy surgery”, un Pubmed, EMBASE, Medlink Scielo. Most cutting edge, controversial subjects surrounding this field were considered. Results: In comprehensive review, we explore indications, usefulness, discoveries interictal ictal findings, pitfalls, advances science presurgical stereo-encephalography epilepsy. Conclusions: Intracranial recording follows original concepts since its development by Bancaud Talairach, but great made field. Stereo-electroencephalography growing study, establishment pattern complexities.
