Abstract: Objective:To assess the predictive capability of multimodal intraoperative neurophysiologic monitoring(MIOM) in decompression for intramedullary spine tumors. Methods: Thirty-four cases of intramedullary spine tumors were treated with MIOM [somatosensory evoked potentials(SSEP), motor evoked potentials(MEP) and electromyography(EMG)]. Preoperative and postoperative neurologic status and intraoperative neurophysiologic data were collected. Results:Intramedullary spinal cord tumors in 34 cases were completely removed in 28 cases, and partially in 6 cases. Twenty-one cases met inclusion criteria with 14 transient changes and 7 persistent changes. Six cases developed new neurologic deficits after surgery and 2 of them had obtained recovery in the 6-months follow-up. MIOM long-term negative predictive capability was 100%while positive predictive capability was 57.1%. Conclusion:MIOM in intramedullary spinal cord lesions can accurately locate nerve injury during operation and effectively protect the nerve functions. Signal changes in MIOM can predict postoperative spinal cord nerve function.
