Objective: To investigate the successful rate and accuracy of percutaneous radiofrequency thermocoagulation PRT for treatment of primary trigeminal neuralgia PTN with customized navigated template via three dimensional 3D printing technique. Methods: 65 patients with PTN were recruited from January 2014 to March 2015 and randomly divided into two groups: template group n = 28 and traditional group n = 37. The patients in traditional group received PRT under guidance of C-arm fluoroscopy, while the ones in template group were treated with customized navigated templates. The data of time, depth and accuracy rate of puncture, the average effective dose equivalent of radiation, complications after operation were collected and analyzed. Results: No intra-operative failures occurred in the template group: the pain was alleviated immediately after operation. Accuracy rate of the template group was 100% while 96% was achieved in traditional group. However, the average time of puncture by the template was significantly reduced compared with traditional group 2.37 ± 0.64 minutes and 24.2 ± 6.55 minutes, respectively; P < 0.001. Meanwhile, the average effective dose equivalent of radiation was apparently reduced compared to the traditional group. The depth of puncture in operation was mostly close to the results of simulation 9.45 ± 0.58 cm and 9.33 ± 0.87 cm respectively, P > 0.05. No complications were observed in template group while several complications such as blooding, leakage of cerebrospinal fluid and dizziness were observed in traditional group. Conclusion: The application of customized template is advocated for improving the accuracy of PRT.
