- Abstract
Although pulsed radiofrequency treatment ( PRFT) has been used to treat trigeminal neuralgia ( TN) safely, satisfactory improvement is lacking. Recently, much attention has been paid to the PRFT dose and intra-operative parameters. It has been reported that high-voltage PRFT could significantly reduce discogenic pain. However, there is no study investigating the effects of high-voltage PRFT on TN. The aim of this prospective, randomized, double-blinded study was to evaluate the efficacy and safety of high-voltage PRFT in comparison with standard-voltage PRFT for idiopathic TN. Sixty severe TN patients were randomly assigned to 2 groups treated with CT-guided standard- or high-voltage-pulsed radiofrequency ( RF) of Gasserian ganglion, respectively, between January 2012 and July 2012. Numeric Rating Scales ( NRS), carbamazepine dose, and side effects were evaluated at day 1, weeks 1 and 2, months 1, 3, and 6, and 1 year postoperative. There were 27 patients in the standard-voltage group and 26 patients in the high-voltage group who completed the 1-year follow-up study. The effective rates in the standard-voltage and high-voltage PRFT groups were 41% and 69%, respectively, at 1, 3, and 6 months postoperative ( P = 0.037). The effective rate in the standard-voltage group decreased to 19% at 1-year postoperative, while in the high-voltage group remained at 69% ( P = 0.000). No significant side effects were detected in both groups. In conclusion, CT-guided high-voltage PRFT is an effective and safe interventional therapeutic choice for idiopathic TN patients.
