Clinical analysis of CT guided percutaneous radiofrequency thermocoagulation for treatment of trigeminal neuralgia

Objective To analyze and evaluate the clinical effect of CT guided percutaneous semilunar ganglion radiofrequency thermocoagulation for treatment of trigeminal neuralgia.Methods 52 patients with trigeminal neuralgia treated in our hospital were selected.They underwent the CT three-dimensional guidance on trigeminal neuralgia Ⅱ,Ⅲ,Ⅱ + Ⅲ neuralgia neuralgia patients with anterior foramen ovale puncture semilunar ganglion,verify the operative target,and a standard radiofrequency target temperature damage under general anesthesia.Results Of the 52 patients,the treatment effect was excellent in 49 cases,good in 1 patient,the effect of other 2 cases was poor,the excellent and good rate was 96.15％.Conclusion CT guided percutaneous puncture semilunar ganglion radiofrequency thermocoagulation in the treatment of patients with trigeminal neuralgia is simple,safe,and easy to be accepted by patients,the cure rate is high,it is worth learning and promotion.
