Abstract

Abstract: Objective: To investigate the effect of intraoperative and postoperative treatment of trigeminal neuralgia through puncture of foramen ovale assisted by 3D printing tooth supported guide plate. Methods: Forty patients with trigeminal neuralgia from January 2019 to May 2021 were randomly divided into 2 groups. Group A (Control group): foramen ovale was punctured according to Hartel's anterior approach, and radiofrequency therapy was performed after the foramen ovale was penetrated and the cranial depth was determined by ear-bed line positioning. Group B (Guide plate group): the puncture was guided by 3D guide plate, and radiofrequency therapy was performed after cranial depth was determined by ear-bed line positioning. Visual analogue score (VAS) before and after operation, pain disappearance immediately and 1 month after surgery, operative time, number of puncture, complications, and puncture deviation degree were analyzed in both groups. Results: Compared with control group, there were no significant differences in the pain disappearance immediately and 1 month after surgery (P>0.05). There were significant differences in the number of puncture, puncture deviation degree, operation time, and complications between two groups (P<0.05). The guide plate closely adapted to the teeth. Conclusion: Using 3D printing guide plate to puncture foramen ovale has obvious advantages, which can reduce patient trauma, reduce X-ray radiation, and reduce puncture deviation.
