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

Beijing Tiantan Hospital·interventional·Posted Nov 22, 2019·Updated Aug 6, 2024

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.

Interventions

High-voltage pulsed radiofrequencyprocedure

2 Hz of pulsed radiofrequency will be administered at a voltage of 70 V, temperature of 42 °C, pulse width of 20 ms, and treatment time of 600 s.

Low-temperature continuous radiofrequencyprocedure

Low-temperature continuous radiofrequency will be performed at 60 °C, with a treatment time of 270 s.
