Abstract:

Objective To explore the preoperative application of 3D ⁃ SLicer software in the resection of cerebellopontine Angle tumor，so as to provide a better auxiliary means for precise surgery. Methods From 2018 to 2019，20 patients with pontine Angle tumors were collected from the Neurosurgery Department of the Second Affiliated Hospital of Zhengzhou University. Before surgery，3D⁃SLicer software was used to reconstruct the sinus， skull and skin，and design skin incisions and bone flaps. Results According to the results of 3 d reconstruction， all the surgical approaches were successfully designed to find the tumor in the best position and to protect the venous sinus and brain tissue. All the 20 cases were successfully completed，and the 3D reconstructed images were basically consistent with the actual intraoperative findings. Conclusions 3D⁃SLicer software can provide objective and accurate positioning for the resection of tumors in the cerebellopontal Angle area，help understand the location of blood vessels and nerves，avoid the yaw of the surgical path，and improve the success rate of the operation.
