title: Pulsed radiofrequency treatment for idiopathic trigeminal neuralgia: a retrospective analysis of the causes for ineffective pain relief.
abstract: We retrospectively analyzed the reasons for ineffective pain relief in patients with idiopathic trigeminal neuralgia (TN) who had undergone pulsed radiofrequency (PRF) treatment guided by computed tomography scan. We found that intraoperative PRF output voltage and electrical field intensity was significantly higher (p < 0.05) in the group who had received effective treatment than in the ineffective group. These findings suggest that optimizing PRF parameters and increasing the intraoperative output voltage (electric field intensity) may therefore, provide better pain relief in patients with TN.
