OBJECTIVE

To explore the application of intracranial electrodes (IE) for temporal lobe epilepsy (TLE) surgery and assess the clinical utility of intracranial video electroencephalography (IVEEG).

METHODS

The clinical data of 60 TLE patients undergoing implantation of IE were reviewed retrospectively. Cortical subdural strip, grids and depth electrodes were implanted by sphenotresia, bone disc craniotomy or stereotactic technology.

RESULTS

The implanted electrodes were as follows: frontal-temporal lobe cortical strip (n = 34), frontal-anterior temporal-occipitotemporal lobe cortical strip (n = 7), bilateral temporal lobe cortical strip (n = 7), combined temporal lobe strip & depth (n = 7), anterior temporal-occipitotemporal junction cortical strip (n = 3) and combined strip & grid (n = 2). The following procedures were performed: anterior temporal lobectomy (ATL) (n = 50), combined ATL & frontal focal cortical resection (n = 7), combined ATL & callosotomy (n = 1) and combined neocortex epileptogenic focus resection & amygdalohippocampectomy (n = 2).
