Evaluation Of Csep Joint Dcs In The Positioning Of Cerebra Motor And Sensory Function Areas

Basic motor area lesions in surgical treatment of neurological surgery has always been one of the difficulties, the main contradiction is the extent of lesion resection and nerve function of trade-offs, especially in patients with glioma survival and quality of life is closely related with the extent of surgical resection. In recent years, neural electrophysiological monitoring techniques with the development and application of functional areas to promote brain lesions model from anatomy to the anatomy - functional changes.Objective cortical somatosensory evoked potential waveform inversion joint direct electrical stimulation to help determine the sensory area, the basic motor areas and subcortical motor conduction pathway, the maximum removal of lesions retained sensory area, the basic motor areas and subcortical motor conduction pathway, by monitoring muscle group and the group was not detected, resection extent, to evaluate the clinical value of combined detection.Methods Method of Monitoring Group in June 2008 -2009 on June motor and sensory function area occupying 40 patients, both intraoperative cortical somatosensory evoked potentials by waveform inversion joint direct electrical stimulation positioning motor and sensory function area. Not detected Group: June 2008 -2009 on June motor and sensory areas occupying 40 patients, no intraoperative cortical somatosensory evoked potentials by waveform inversion, and direct electrical stimulation positioning motor and sensory areas. Two groups of patients are using neurological examination before and after surgery to 2 weeks after operation as the starting point, the patient's muscle strength were evaluated, as the removal of the degree evaluation.Results Comparing two sets of data, monitoring group, 40 out of 14 patients decreased muscle strength, (35%). Section 40 was not detected among the 21 patients decreased muscle strength (accounting for 52.5%) P=0.028 (P<0.05); monitoring group, nine cases of successful surgery to set down movement pathway (22.5%), 9 cases in four cases of muscle strength improved after 2 weeks, 4 cases decreased muscle strength compared with that before, one case of preoperative muscle strength and consistency. Decreased muscle strength of 4 cases were followed up 3 months after surgery in 3 patients returned to preoperative levels, one case of left lasting motor dysfunction. Monitoring group of people feeling diminished after 2 (5%), did not monitor the group were feeling diminished in 1 case (accounting for 2.5%) P= 0.841 (P > 0.05); monitoring group of the 28 cases all, 12 cases of near total cut; not monitored 27 patients with total resection, 13 cases of near total resection, no significant statistical difference (P=0.809).Conclusions The use of intraoperative cortical somatosensory evoked potential waveform inversion and direct cortical electrical stimulation and downlink channel monitoring exercise, can effectively protect the motor function and improve quality of life in patients with high clinical value.
