Abstract:

Objective To investigate the clinical effect of 3D slicer combined with sina software assisted percutaneous balloon compression in the treatment of trigeminal neuralgia. Methods A total of 65 patients with trigeminal neuralgia from June 2019 to June 2021 were enrolled and divided into 3D⁃Slicer combined with Sina assisted puncture surgery group（observation group，n = 35）and traditional freehand positioning puncture surgery group（control group，n = 30）according to different surgical procedures. The operative time，puncture time，puncture frequencies，intraoperative fluoroscopy frequencies，intraoperative ray volume，number of balloon malformation， pain intensity scores at Barrow Neurological Institute（BNI）on the 1st day after operation and the prognosis within 6 months after operation were compared. Results The operation time，puncture time，puncture frequencies，intra⁃ operative fluoroscopy frequencies and intraoperative radiation volume in the observation group were significantly than those of the control group（P < 0.05）. There was no statistical significance in the number of balloon malforma⁃ tion and the rate of complete pain relief（BNI grade I）on the first postoperative day between the two groups（P > 0.05）. Follow⁃up within 6 months after surgery，there was no significant difference in the incidence of facial numb⁃ ness，diplopia，masseter weakness，keratitis，herpes labialis，vascular injury and recurrence between the two groups（P > 0.05）. Conclusion 3D slicer combined with sina software could assist precise and fast puncture of foramen ovale and injection of appropriate contrast agent for compression；It has the advantages of shortening the time of puncture and operation，reducing the number of puncture and fluoroscopy，and reducing the amount of intraoperative rays.
