This study is looking at a new way to improve personalized mapping during percutaneous rhizotomy, a procedure for trigeminal neuralgia (severe facial pain). Researchers will test the feasibility of adding trigeminal somatosensory evoked potentials (TSEPs) to the standard rhizotomy procedure. This involves recording electrical signals from your brain (EEG) and from the trigeminal ganglion (a nerve cluster in your head) before and after the procedure. The goal is to see if these measurements can help doctors better target the treatment. You may be able to join if you are an adult (18 or older) scheduled to have a percutaneous rhizotomy for facial pain. The study aims to determine if this new measurement technique is possible over a three-year period. The current recruitment status is unclear.

Study design

This is an observational study planning to include 30 participants. It will involve measuring electrical signals during your scheduled percutaneous rhizotomy procedure.

What's involved

You would undergo the trigeminal electrophysiology procedure during your routine percutaneous rhizotomy. This involves recording electrical signals from your scalp and the trigeminal ganglion.

Compensation

Not stated in the trial record.

Follow-up

The primary goal of the study will be measured at 3 years.
