Title: Comparison of radiofrequency thermocoagulation through oval foramen and pterygopalatine fossa in the treatment of idiopathic trigeminal neuralgia
Abstract: Objective To evaluate the efficacy and side-effect of radiofrequency thermocoagulation through oval foramen and pterygopalatine fossa in the treatment of idiopathic trigeminal neuralgia(maxillary nerve).Methods 30 patients with idiopathic trigeminal neuralgia(maxillary nerve) were included.The patients were randomly assigned to the two groups(Group A and B).Each patient in the Group A was treated with radiofrequency thermocoagulation through oval foramen,whereas each patient in the Group B was treated with radiofrequency thermocoagulation through pterygopalatine fossa.Evaluation parameters were pain intensity using a Visual Analogue Scale(VAS),patient satisfaction using a Patient Satisfaction Scale(PSS),additional side effects and complication related to the technique.Results The VAS scores decreased significantly(P0.05) and PSS improved significantly(P0.05) after the procedure in both Group A and Group B,respectively.Follow-up 6 months,the efficacy of the two groups were similar,but Group B was less side-effect than Group A.Conclusion Radiofrequency thermocoagulation through pterygopalatine fossa is effective for treatment of idiopathic trigeminal neuralgia(maxillary nerve),with less side-effect.
