What this trial studies

This clinical trial aims to compare the effectiveness and safety of two methods of trigeminal ganglion radiofrequency thermocoagulation (TG-RFT) for treating idiopathic trigeminal neuralgia in adults. Participants will be randomly assigned to receive either CT-guided or fluoroscopy-guided TG-RFT and will be monitored for pain relief, medication use, and any adverse events over a six-month period. The study seeks to determine if one method offers superior pain relief and safety compared to the other.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old diagnosed with idiopathic trigeminal neuralgia who have experienced significant pain for at least six months despite medical treatment.

Not a fit: Patients with secondary causes of trigeminal neuralgia, such as multiple sclerosis or those with certain medical conditions like coagulopathy, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide patients with a more effective and safer treatment option for managing severe facial pain associated with idiopathic trigeminal neuralgia.

How similar studies have performed: While the specific comparison of CT-guided versus fluoroscopy-guided TG-RFT is novel, radiofrequency thermocoagulation has been established as a treatment for trigeminal neuralgia in other studies.
