Trigeminal somatosensory evoked potentials in surgical management of trigeminal neuralgia

Both examination of trigeminal somatosensory evoked potentials and testing trigeminal nerve involvements associated with various neurological diseases make it possible to objectively measure the sensitivity and correlation of clinical symptomatology with the electrophysiological parameters. This procedure is described as applied to patients with essential trigeminal neuralgia and the effect of retrogasserian thermocoagulation upon the studied parameters is analyzed.
