ABSTRACT
Objective To evaluate the clinical effect of CT-guided radiofrequency thermal coagulation in treating primary trigeminal neuralgia.Methods A total of 165 patients with primary trigeminal neuralgia were selected as research objects.The patients were randomly divided into radiofrequency thermal coagulation group (study group,n=83) and drug damage group (control group,n=82).For the treatment of trigeminal neuralgia,CT-guided radiofrequency thermal coagulation was carried out in the patients of the study group,and CT-guided percutaneous puncturing of oval foramen with epirubicin injection as chemical damage therapy was employed in the patients of the control group.Follow-up check-up was conducted at 3,6,12 and 36 months after the treatment.Visual analog score (VAS),total effective rate and incidence of complications were calculated and the results were compared between the two groups.Results The excellent therapeutic rate of the study group was significantly better than that of the control group,the difference between the two groups was statistically significant (P＜0.05).The incidence of complications in the study group was remarkably lower than that in the control group,the difference between the two groups was statistically significant (P＜0.05).The VAS pain score of the study group was much lower than that of the control group.The total therapeutic effect in the study group was more prominent.Conclusion In treating primary trigeminal neuralgia,CT-guided radiofrequency thermal coagulation has excellent clinical effect.Therefore,this technique is worthy of popularization and application in clinical practice.
