UNASSIGNED: @entity4847 and @entity1653 account for most intradural extramedullary (IDEM) @entity5 . These @entity5 are benign and amenable to complete surgical resection. In recent years, these surgeries are performed with intraoperative neurophysiologic monitoring (IONM) in order to minimize @entity16 , but the evidence for the statistical efficacy of this utility is lacking. This paper evaluates IONM benefits in IDEM @entity5 resection. Data of @entity1 treated surgically for spinal intradural @entity5 from 1998 to 2003 was previously collected and analyzed. We retrospectively evaluated @entity1 ' charts operated in the years 2011 to 2013. @entity1 ' medical files were reviewed including radiological examinations and electrophysiological reports. The data was collected and evaluated. Forty-one cases of @entity1653 or @entity4847 resection surgery were performed in the study period. The surgical results were compared to 70 cases of historical controls. Demographic data was similar in these two groups. Sensitivity, specificity, and positive and negative predicted values of IONM were 75, 100, 100, and 97%, respectively. New @entity51 rate was evident in 10 and 14% for the study and control groups, respectively (not significant). While IONM predicts @entity51 with high accuracy level, this study does not suggest that there is a significant global benefit of IONM in these cases. As reported by others, in this series, the rate of new @entity51 in non-monitored cases is similar to the monitored cases series; hence, IONM role in preventing new @entity51 has yet to be proven.
