The Efficacy and Safety of the Application of Pulsed Radiofrequency, Combined With Low-temperature Continuous Radiofrequency, to the Gasserian Ganglion for the Treatment of Primary Trigeminal Neuralgia
In Brief
A clinical study evaluating High-voltage pulsed radiofrequency and Low-temperature continuous radiofrequency for Trigeminal Neuralgia. Completed, enrolled 146 participants across 1 site.
Detailed Summary
Trigeminal neuralgia is a very painful condition, and radiofrequency therapy is reserved for patients who are resistant or intolerant to pharmacological therapy. Continuous radiofrequency and pulsed radiofrequency both have advantages and disadvantages. Recently, studies have found that pulsed radiofrequency combined with low-temperature (\<65 °C) continuous radiofrequency increases the efficacy of the treatment, without leading to a significant increase in complications caused by nerve lesions. However, these reports have some limitations. The investigators plan to conduct a randomized, controlled study to compare the efficacy of applying high-voltage pulsed radiofrequency, with and without low-temperature continuous radiofrequency, to the gasserian ganglion for the treatment of trigeminal neuralgia. The primary outcome will be the effectiveness of the treatment after 12 months which is the percentage of participants with a modified Barrow Neurological Institute Pain Intensity Score between I-III.
