Trigeminal Neuralgia Electrophysiology

NCT05269472 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 30

Last updated 2025-11-19

No results posted yet for this study

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.

Conditions

  • Trigeminal Neuralgia

Interventions

PROCEDURE

Trigeminal Electrophysiology

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.
