[Intracranial electrode recording prognostic value in anterior temporal lobectomy and hypocampectomy].

Unlabelled: The experience obtained in the Epilepsy Clinic of the General Hospital of México in regard to the use of intracraneal electrodes to determine the epileptic tissue that must be resected in an anterior temporal lobectomy with amygdalo-hippocampectomy in patients with intractable mesial temporal lobe seizures is described. The data obtained while recording the electroencephalographic activity with these electrodes to learn about its impact in the postsurgical result (seizure reduction and complications) both in the first year and long-term (up to 17 years) follow-up was analyzed. Fifty seven patients implanted between years 1993-2008 were included.
