Microsurgical Treatment Of Temporal Epilepsy

Objective:To explore the methods of presurgical location in patients with temporal lobe epilepsy,electrocorticogram (ECoG).monitoring in the surgical treatment of temporal lobe epilepsy and control of postoperative complications.Methods:The clinical data of 87 postoperative patients from 2nd XiangYa Hospital, from 2006 to 2009, who underwent surgical treatment of temporal lobe epilepsy were retrospectively analyzed. All the patients were monitored by Video electroencephalography(VEEG) and Magnetic Resonance Imaging(MRI) before operation, by electrocorticogram (ECoG)monitoring in the operation. Patients were closely monitored with MRI postoperative.Results:All patients according to the video electroencephalogram (VEEG) and magnetic resonance imaging (MRI) located epileptogenic zone as a noninvasive check. By using electrocorticogram (ECoG)monitoring in the operation,we can know the position and range of epileptogenic zone better.Taking an antiepileptic drug at least 2 year after operation, According to the clinical onset, EGG results determineed whether withdrawal.87 patients were followed up for 1 year to 2 years, the clinical attack was controlled completely in 71(81.6%) patients(Engel-â… ), the times of clinical attack were decreased significantly in 12(13.8%) patients(Engel-â…¡),4(4.6%) patient still to remain epileptic seizure, but the degree relieved, and the seizure time shortened(Engel-â…¢). The nerves psychological function improved to different extent in 80patients(91.2%).Conclusions:Using microsurgical techniques for the treatment of temporal lobe epilepsy is a safe and effective method. On preoperative video electroencephalogram (VEEG) and magnetic resonance imaging (MRI) of temporal lobe epilepsy epileptogenic zone resection for accurate positioning, design method had important reference value. By using electrocorticogram (ECoG)monitoring in the operation,we can know the position and range of epileptogenic zone better. While epileptogenic zone resection of the lesion and control seizures, improve the prognosis of effective means, and reduce the complications, enhance the curative effect of the key.
