Abstract：Objective To explore the efficacy of microsurgical treatment of high cervical spinal cord tumors under the assistance of intraoperative neurophysiological monitoring and ultrasound.Methods The clinical data of 26 patients with high cervical spinal cord tumors admitted from March 2018 to June 2022 were retrospectively analyzed.All patients underwent microsurgical treatment via the posterior median approach under the assistance of intraoperative neurophysiological monitoring and ultrasound.Results Postoperatively,total tumor resection was achieved in 22 patients,partial resection in 3,and biopsy plus laminectomy in 1.Postoperative pathology confirmed 8 schwannomas,6 meningiomas,4 ependymomas,4 astrocytomas,3 hemangioblastomas,and 1 cavernous hemangioma.One week after surgery,McCormick grade Ⅰ was achieved in 20 patients,grade Ⅱ in 4,and grade Ⅲ in 2.At 6 months postoperatively,McCormick grade Ⅰ was achieved in 22 patients,grade Ⅱ in 2,and grade Ⅲ in 2.No cerebrospinal fluid leakage or intracranial infection occurred postoperatively.Conclusions The surgery for high cervical spinal cord tumors,especially intramedullary tumors,is highly challenging and demanding,with total resection being difficult.Intraoperative neurophysiological monitoring and ultrasound can enhance the safety and efficacy of the surgery,and are of significant value in achieving total tumor resection and maximizing the preservation of neurological function.
