Aims: To present our spinal intradural tumor series and to evaluate the reliability of electrophysiological assessment in patients treated for these tumors. Methods: We retrospectively evaluated the data of patients treated for spinal intradural tumor between 2010 and 2019. The demographic, surgical and histological features of patients were evaluated and compared with their pre- and postoperative electrophysiological data. Somatosensory evoked potentials (SEP) were used as electrophysiological test. Results: A total of 69 patients with spinal intradural tumor was evaluated. Thirty-one of them had extramedullary and 38 had intramedullary tumor. The mean age was 48.3 years for extramedullary and 26.3 years for intramedullary tumors. In preoperative period, SEP was prolonged in 25 patients with intramedullary tumor while it was prolonged in 8 patients with extramedullary tumor. In postoperative period, recovery in SEP values was detected in 5 of 25 patients with intramedullary tumor but it was observed in 7 of 8 patients with extramedullary tumor. Conclusions: Electrophysiological evaluation is a safe and reliable method to assess the patients surgically treated for spinal intradural tumor. It is an objective method to evaluate the neurological recovery of patients with extramedullary tumor.
