A Comparative Study of Post-Operative Outcomes with and without Using Intraoperative Neurophysiological Monitoring in Intra Medullary Spinal Cord Tumors Surgeries; A Systematic Review

Abstract Background Although relatively infrequent, neurological injury is a much dreaded complication in spine surgery and has the potential to result in serious postoperative motor and sensory deficits. As a result of these surgical challenges, intraoperative neuromonitoring (IONM) has gained favorable grounds in facilitating maximal tumor resection and minimizing neurologic morbidity. Aim and Objectives to review the efficacy of intraoperative neurophysiological monitoring (IONM) on post operative outcomes preventing neurological injury, predicting post operative neurological deficit and its effect on intraoperative surgeon’s decision making, and to know if it is beneficial or not in intramedullary spinal cord tumors surgeries in adults. Subjects and Methods This was observational studies and non randomized controlled studies. our patients were followed up according to this schedule (immediate post operative, first day, three days, first month, three months, six months, one year post operative) and the assessment were done by using Oxford grading system. Result Regarding neurological status by clinical examination at last follow up, Improved in 72, transient worsening in no cases, no change in 12 cases and progression in 17 cases, Conclusion. Conclusion our systematic review of the literature indicates that there is strong evidence that multimodality neuromonitoring is sensitive and specific for detecting intraoperative neurologic injury during spine surgery. Although the level of evidence supporting the conclusion that intraoperative neuromonitoring reduces the rate of new or worsening neurologic deficits is low, the available evidence does consistently support this conclusion.
