Abstract:
This review deals with the diagnostic usefulness of neurophysiological testing in patients with craniofacial pain. Neurophysiological testing of trigeminal nerve function relies on trigeminal reflexes and laser-evoked potentials (LEPs). This review briefly describes the physiology of trigeminal reflexes and LEPs, reports normal values and highlights the neurophysiological abnormalities in the main clinical conditions.
