Value Of Application Of Intraoperative Electrocorticography Monitoring For Patients Undergoing Supratentorial Tumor Resection Operationa

Objective:To discuss the value of application of intraoperative electrocorticography monitoring for patients undergoing supratentorial tumor resection operation.Methods:All literatures related to this issue were firstly collected. Finally, this summary was composed of the most representative articles chosen for quotation after carefully were read and sorted.Results:1. Most literatures showed that many supratentorial tumors, especially supratentorial tumors with epileptic seizure, had epileptic discharge around the tumor foci; 2. Besides signature waveform, such as spike wave, as the traditional and widely acknowledged epileptogenic foci location method, initial slow wave and high frequency shock wave had relatively high value in locating epileptogenic foci; 3. Most literature advocated that foci resection and epileptogenic foci treatment under the intraoperative electrocorticogram (ECoG) monitoring could reduce the incidence of postoperative seizure; 4. Some literatures indicated the characteristic of wave in ECoG monitoring has certain instructive value for the forecast of occurrence of postoperative primary epilepsy.Conclusion:The intraoperative electrocorticogram (ECoG) monitoring is a simple, objective, convenient and easy monitoring tool. Using electrocorticogram (ECoG) monitoring in the supratentorial tumor resection operation could reduce the incidence of postoperative epilepsy. Studying the characteristic of wave in ECoG monitoring before and after the resection of foci has certain instructive value for the location of epileptogenic foci, and it also has forecast value for the occurrence of postoperative primary epilepsy.
