Background:The aim of our study is to evaluate the results of percutaneous radiofrequency trigeminal rhizotomy for the treatment of idiopathic trigeminal neuralgia. Methods:We inspected the results of 106 patients who were diagnosed as idiopathic neuralgia and treated with percutaneous radiofrequency trigeminal rhizotomy retrospectively. Visual analog scale(VAS) scores preoperative and postoperative first, third, sixth and twelfth months were used for statistical analyse. Results:Mean age of 106 patients was 67.31± 8.85 years. Duration of symptoms was 19.1±13.1 months. Duration of symptoms did not change significantly according to gender (p=0.755), or site of trigeminal pain (p=0.158). There was no relation between effected branch of trigemial nerve and gender and site of the pain. Preoperative mean VAS score was 9.6±0.75. Postoperative mean VAS score values were 3.25±2.44 at first month, 3.23±2.43 at third months, 3.12±2.78 at sixth months and 2.59±3.18 at postoperative twelfth months. There was statistically significant difference between preoperative and postoperative first, third, sixth, and twelfth months VAS scores (p<0.001). Conclusion:Percutaneous radiofrequency trigeminal rhizotomy has lower risk when compared with invasive surgery, with a high rate of efficacy and the most cost-effective procedure may safely be repeated if pain recurs.
