Résumé
Objective:To investigate the effect of microsurgery by modified pterional approach in the treatment of temporal lobe epilepsy under intraoperative cortical encephalon electricity graph (EEG) monitoring.Methods:The clinical data of 32 patients with temporal lobe epilepsy who were admitted to the Department of Neurosurgery of Shangqiu First People's Hospital from January 2012 to June 2021 were retrospectively analyzed, all patients underwent microsurgical resection of epileptogenic foci by modified pterional approach under cortical EEG monitoring.Results:The postoperative follow-up was from half a year to 6 years. According to the Tan's classification, 25 cases (78.1%(25/32)) of seizures disappeared completely, 3 cases (9.4%(3/32)) of seizures decreased by more than 75%, and 4 cases (12.5%(4/32)) of seizures decreased by more than 50%. Isotropic hemianopia occurred in 1 case (3.1%) after operation, and there was no operative death.Conclusion:Microsurgical resection of epileptogenic foci through modified pterional approach under intraoperative cortical EEG monitoring was a safe and effective method for the treatment of temporal lobe epilepsy.
