Abstract:Objective: To investigate the efficacy and safety of three core puncture in Percutaneous Balloon Compression(PBC) for primary trigeminal neuralgia(PTN). Methods: Eighty patients with primary trigeminal neuralgia admitted to Heze Municipal Hospital and the Second Affiliated Hospital of Guangxi Medical University from January 2021 to October 2021 were randomly divided into single core puncture group (group D, 40 patients) and three needle core puncture group (group S, 40 patients). Both groups were treated with dyna-CT guided trigeminal ganglion balloon compression. The data of puncture frequency, operation time, balloon expanded volume and some complications of balloon rupture, facial herpes, numbness, diplopia and keratitis was collected and compared between the two groups. The NRS scores of patients at the time of preoperative ,posteoperative 1 day,1 month and 6 months and efficacy of 6 months’ follow-up were compared between the two groups. Results: The puncture frequency in group D was more than that in group S (P < 0.05), and the operation time in group D was longer than that in group S (P < 0.05). There was no statistical difference in balloon expanded volume and balloon rupture times between the two groups. The NRS scores of both groups at various time points postoperatively were lower than those before operation (P < 0.05), and the NRS scores at 1 month and 6 months postoperatively of both groups were lower than that at 1 day after operation (P < 0.05). There was no significant difference in efficacy between the two groups at six months after operation. There was no significant difference in the incidence of facial herpes, numbness, diplopia and keratitis between the two groups. Conclusion: There is no difference in efficacy and safety between three needle core puncture method and the single core puncture method, but the three core puncture method can significantly reduce the puncture frequency and shorten the operation time, which is worthy of recommendation.
