ClinConnect Summary

This clinical trial is looking at a technique called Trigeminal Somatosensory Evoked Potentials (TSEPs) to see if it can help improve a surgical procedure called rhizotomy for people suffering from trigeminal neuralgia (TGN). TGN is a condition that causes severe, shock-like facial pain. The researchers want to find out if using TSEPs during the rhizotomy procedure is practical and beneficial for patients. This study will include adults aged 18 and older who are scheduled to have the rhizotomy surgery for their facial pain.

If you or a loved one has been diagnosed with TGN and are planning to undergo rhizotomy, you might be eligible to participate in this trial. Participants will undergo the standard rhizotomy procedure, and the researchers will monitor the TSEPs to gather data. It's important to note that patients with unclear facial pain origins or certain other pain conditions will not be eligible for this study. This trial is currently recruiting participants, and it offers a chance to contribute to understanding and potentially improving treatment for TGN.
