Abstract：Objective To explore the effect of application of C-arm guidance combined with electrical stimulation in trigeminal neuronal radiofrequency coagulation therapy for primary maxillary neuralgia. Methods 50 cases of patients with primary trigeminal maxillary neuralgia of the Ⅱ branch treated in the Affiliated Huai′an Hospital of Xuzhou Medical University from January 2012 to December 2015 were selected, and randomly divided into the observation group and the control group, each group had 25 cases. All patients were treated by C-arm guided modified Hartel approach through foramen ovale into the trigeminal ganglion. The control group was treated with radiofrequency coagulation guided by C-arm, the observation group was combined with electrical stimulation directing. The visual analogue scale (VAS), excellent rate, recurrence rate and complications of the two groups were follow-up in preoperative and postoperative instantly, 1 month, 3 months, 6 months and 12 months after operation. Results Both the control group and the observation group were followed up completely. The VAS scores of postoperative instantly, 1 month, 3 months, 6 months and 12 months after operation in the observation group were obviously lower than those of the control group, and the differences were statistically significant (P < 0.05). The excellent rates of the observation group were higher and the recurrence rates were lower than those of the control groups, with statistically significant differences (P < 0.05). The incidence of numbness in mandibular nerve zone of Ⅲ branch was lower in the observation group than that in the control group, with statistically significant difference (P < 0.05). There was no significant difference in complications between the two groups (P > 0. 05). Conclusion Compared with C-arm guidance, combined with electrical stimulation has higher location accuracy, better clinical effects and lower recurrence rate.
