About the study
Trigeminal neuralgia (TGN) is a debilitating pain syndrome where electrical, shock- like jolts of pain affect the face. Trigeminal somatosensory evoked potentials (TSEPs) provide a promising modality for measuring the trigeminal sensory and nociceptive pathway by using peripheral stimulation of the trigeminal nerve (on the skin) and measuring low latency evoked potentials on the scalp (contralateral sensory cortex). While TSEPs have been measured in the past, it is not clear if implementing TSEPs into a routine neurosurgical rhizotomy procedure will be feasible. This is a prospective cohort study examining the feasibility of routinely performing TSEPs during rhizotomies for TGN.
