Abstract: Objective To investigate the Leksell framework stereotactic eeg (L - SEEG,Leksell-stereoelectroencephalography.) technology,the positioning island wild leaf and suspicious application of lobe epilepsy.Methods In ten epileptic patients,83 SEEG electrodes were implanted using the Leksell frame,per average (8 ± 2) root,including 984 contacts,38 electrodes involving the insula and 151 contacts.After implantation,the Nicolet 256 guided EEG system was used for long-range video EEG monitoring,and more than 3 habitual episodes occurred.Epictal and interictal figures were recorded to identify the epileptic foci.Results In this group of 10 patients,the onset of scalp EEG was temporal lobe or frontal lobe,but the onset of intracranial EEG was insula lobe.Among them,suspected insular attack,intracranial EEG starting from temporal lobe or frontal lobe;All 10 patients underwent surgical resection of epileptogenic foci.In this group,there were no complications caused by electrode implantation,such as electrode removal,intracranial hematoma and intracranial infection.The patients were followed up for 1~3 years and given 1~3 kinds of antiepileptic drugs.Engel grading was performed according to the postoperative results,including 6 cases of grade I,3 cases of grade II,and 1 case of grade III.Conclusion L-SEEG has less trauma,fewer complications and is accurate.It can be used in suspected insular epilepsy to identify epileptogenic foci and improve the cure rate.
