Anterior Temporal Resection Appendant with Selective Amygdalohippocampectomy under the Location of ECoG for Refractory Temporal Lobe Epilepsy

Objective To investigate the efficacy of anterior temporal resection appendant with selective amygdalohippocampectomy under the location of ECoG for refractory temporal lobe epilepsy. Method 21 cases of refractory temporal lobe epilepsy confirmed by electroencephalogram, CT, and MRI preoperatively underwent the operations mentioned above. Result No morbidity and mortality occurred in this group.During 8 months to 3 years follow-up,the effect was satisfactory in 9 cases, obviously improved in 8 cases, false in 2 cases, false in 2 cases. 90.5% patients' seizure frequency decreased more than 50%, 81.0% patients' decreased more than 75%. But all the patients still needed the antiepileptic drug. Conclusion The procedure of anterior temporal resection appendant with selective amygdalohippocampectomy under the location of ECoG is recommended as a safe and effective method for refractory temporal lobe epilepsy, with superiority of clinical efficacy based on the less range of hippocampus resection.
