Measuring nerve responses during facial pain treatment

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to assess somatosensory evoked responses in patients undergoing percutaneous rhizotomy for trigeminal neuralgia. The study will measure these responses at two locations: the contralateral scalp using EEG and at the gasserian ganglion with an FDA-approved electrode. By analyzing these responses before and after the rhizotomy procedure, the study seeks to enhance understanding of the electrophysiological changes associated with trigeminal neuralgia treatment.
