Abstract: Objective To explore the epilepsy form,transmission network,diagnosis and treatment methods of supplementary motor area epilepsy.Methods The clinical data of a patient with epilepsy in the supplementary motor area diagnosed and treated with the aid of stereotaxic technology in our department were sorted out,and the clinical symptoms,EEG transmission network and treatment effect were analyzed in combination with domestic and foreign literature.Results After the first-stage evaluation of epilepsy,the patient was determined to undergo SEEG surgery assisted by stereotaxic technology,and entered the second-stage evaluation of epilepsy before epilepsy.After more than 2 months of observation,the patient's seizures increased.After the preoperative evaluation of epilepsy in the first two phases was reviewed again,the epilepsy foci resection was performed under the guidance of neuronavigator and cortical EEG,and the patient was seizure-free 18 months after operation.Conclusion The epileptic discharges from the supplementary motor area are rapidly transferred to the contralateral side through the corpus callosum,and the symptoms appear on both sides of the corpus callosum at the same time.Preoperative comprehensive evaluation cannotdetermine the location of epileptic focus,SEEG localization should be performed.Incomplete thermal coagulation can lead to aggravation of Epilepsy in the supplementary motor area.After excision of the epileptic foci in one SMA area,the patient's language and contralateral limb dysfunction did not appear.
