ABSTRACT
Objective To investigate the combination application of the intracranial buried electrode and electrical stimulation techniques in excising the epileptogenic zone in the central zone.Methods Seven patients with epileptogenic zone located close to or in the central zone of brain were recruited in the present study.The lone term ECoG monitoring and electrical stimulation of the codex were performed to identify the epileptogenic zone and the central zone of the brain after patients received intracranial electrode implants.The epileptogenic zone was excised with maximum preservation of the cen-tral zone.The patients were follow-up for 6 to 12 months,the outcomes were evaluated based on the Engel's scale and the Karnofsky(KPS)score.Results Seven patients did not experience any seizures and their Engei's and KPS scores were markedly improve after operation.Conclusions Intracranial buried electrodes and cortical electrical stimulation can guide the resection of epileptogenic zone in the central zone.Patients have no seizure and no serious dysfunction after operation and their quality of life was improved markedly.
