Objective:To investigate the value of 3D printing combined with intraoperative electrophysiological monitoring in excision of cerebellopontine angle (CPA) tumor.Methods:The clinical data of 43 patients with CPA tumor, admitted to our hospital from October 2016 to October 2019, were collected and analyzed. These patients were voluntarily divided into ordinary group ( n=27) and optimized group ( n=16). Patients in the ordinary group were operated microscopically, and those in the optimized group were operated microscopically with 3D printing combined with intraoperative electrophysiological monitoring. The degrees of tumor resection and neurological functions (facial and auditory nerve function, swallowing function, limb activity) improvements were compared between the two groups. Results:The degrees of tumor resection of the optimized group were significantly higher than those of the ordinary group ( P<0.05), and the improvement of facial and auditory nerve function in the optimized group was significantly better than that in the ordinary group ( P<0.05). There was no significant difference in improvements of swallowing function and limb activity between the two groups ( P>0.05). Conclusion:The 3D printing combined with intraoperative electrophysiological monitoring can improve the resection rate of CPA tumor, protect the facial auditory nerve, and improve the quality of life of patients after surgery.
