The efficacy and safety of percutaneous balloon compression and radiofrequency thermocoagulation in the treatment of primary trigeminal neuralgia
Objective:To compare the efficacy and safety of percutaneous balloon compression with radiofrequency thermocoagulation in the treatment of primary trigeminal neuralgia(PTN).Methods:PTN patients admitted to the Pain Department of China-Japan Friendship Hospital from November 2020 to March 2022 were retrospectively analyzed and divided into percutaneous balloon compression(PBC)group(group P,n = 55)and radiofrequency thermocoagulation(RFT)group(group R,n = 53)according to different operation methods.Visual analogue scale(VAS),total efficacy and complications of the two groups were observed before and 1 hour after surgery.Pain recurrence rates of the two groups were followed up 1 month,3 months,6 months and 1 year after surgery.Results:There was no statistical difference in preoperative VAS score between the two groups,and the VAS score 1 hour after surgery was significantly lower than the preoperative basic value(P<0.01),and there was no statistical difference in the VAS score 1 hour after surgery between the two groups.There was no significant difference in total effective rate between the two groups.The overall degree of facial numbness in group P was less severe than that in group R(P<0.05),and there was no significant difference in herpes labialis,decreased corneal reflex,xerophthalmia and masticatory muscle asthenia between the two groups.There was no significant difference in recurrence rate at 1 month,3 months,6 months and 1 year between the two groups.The recurrence rate was higher in group R after 1 year.Conclusion:Percutaneous balloon compression and radiofrequency thermocoagulation are both effective in the treatment of PTN,and both can cause complications such as facial numbness,and the recurrence rate is higher in the RFT after 1 year.
