Abstract:

Objective To investigate the clinical treatment effect and safety of 3D microscopy technology for adjuvant neuraxial tumor resection on neuraxial tumor diseases. Methods A total of 37 patients with neuraxial tumors treated from January 2019 to July 2023， 15 patients treated with 3D microscope tumor resection （3D group）， and 22 patients treated with general microscope tumor resection （ordinary group） were analyzed. The perioperative indexes， clinical efficacy indexes and safety indexes were compared between the two groups. Results The operation time was （223.78 ± 46.46） min in the ordinary group and （182.93 ± 39.28） min in the 3D group， which was significantly lower than that in the ordinary group （P < 0.05）， and there was no significant difference in other perioperative indicators between the two groups （P > 0.05）. All patients had significantly reduced their postoperative pain symptoms and recovered their neurological function to a certain extent. There were statistically significant differences between the two groups （P < 0.01）， but there was no statistical difference between the two groups （P > 0.05）， and the McCormick spinal cord function rating was grade I. at one year after surgery. Conclusion The use of 3D microscopy and general microscopy for neuraxial tumor surgery has good clinical efficacy. However， the operation time can be significantly shortened under 3D microscopy， thereby reducing the risk of surgical complications and has better clinical safety.
