Trigeminal Neuralgia Electrophysiology
Trigeminal Evoked Responses to Improve Rhizotomy
University of Minnesota
30 participants
Apr 4, 2022
OBSERVATIONAL
Conditions
Summary
The study intervention is to perform standard somatosensory evoked responses limited to the face during rhizotomy procedures of the gasserian ganglion (trigeminal ganglion) for the treatment of trigeminal neuralgia. The evoked responses will be measured at two locations before and after the clinical rhizotomy including: the standard contralateral scalp (EEG) and at the gasserian ganglion through an FDA-approved recording electrode.

Interventions
This study will pilot and test the feasibility of introducing electrophysiology into the routine rhizotomy procedure by including trigeminal somatosensory evoked potentials (TSEPs) and recording from electrodes at the level of the ganglion.
