The study presents a 3D-printed personalized model (3D PPM) for radiofrequency needle guidance in trigeminal neuralgia treatment, reducing radiation exposure and pain during procedures. It showed effectiveness in controlled needle insertion and minimized postoperative complications compared to traditional methods.
• A 3D-printed personalized model (3D PPM) of a radiofrequency needle guide with a maxillary fixator was designed for gasserian ganglion puncture in trigeminal neuralgia treatment.
• 3D PPM reduces radiation exposure and pain during needle insertion, and minimizes postoperative complications.
• The study found that the use of 3D PPM significantly decreased radiation time and dose area product compared to traditional methods.
• Pain severity during the procedure was less in patients using 3D PPM, with more reporting mild pain compared to those not using it.
• Cheek swelling was less frequent in the group using 3D PPM, though not statistically significant due to small sample size.
• The 3D PPM enhances the accuracy of needle insertion and reduces radiation exposure, making it beneficial for less experienced neurosurgeons.
• Limitations include the unsuitability for patients with metal dental implants or missing teeth due to fixation issues.
• Despite limitations, the study shows promising results for 3D PPM in radiofrequency therapy of the gasserian ganglion, suggesting further research is needed.
