Comparing two methods for treating facial pain from trigeminal neuralgia

Comparison of Pulsed and Thermal Radiofrequency for the Treatment of Trigeminal Neuralgia: A Randomized Controlled Trial

Not applicable Interventional Zagazig University · NCT06684275

This study is testing whether a new combination of treatments for facial pain from trigeminal neuralgia works better than a single treatment to help adults feel less pain and improve their daily life.

What this trial studies

This clinical trial aims to compare the effectiveness of Pulsed Radiofrequency (PRF) and a combination of Pulsed and Thermal Radiofrequency (PRF + TRF) in treating adults with Trigeminal Neuralgia (TN). Participants will be randomly assigned to receive either PRF or PRF + TRF treatment targeting the trigeminal nerve. The study will assess pain relief, functional status, and any adverse events over a 12-week follow-up period. The primary outcome will focus on pain reduction measured through established pain scales, while secondary outcomes will evaluate medication consumption and safety profiles.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-60 with a diagnosis of classical trigeminal neuralgia experiencing significant facial pain.

Not a fit: Patients with secondary trigeminal neuralgia or those who have previously undergone surgery or radiofrequency treatment for this condition may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide improved pain relief options for patients suffering from trigeminal neuralgia.

How similar studies have performed: While there have been studies on radiofrequency treatments for trigeminal neuralgia, the specific comparison of PRF versus PRF + TRF is relatively novel.
