Conduction velocity in the human supraorbital nerve.
Maximal conduction velocity in the supraorbital nerve (afferent fibers for the blink reflex) has been estimated in 12 normal subjects (on the right and left side): the mean value was 41 m/s. Furthermore, this investigation was made on 23 patients with different pathologies (9 with trigeminal neuralgia with hypoesthesia, 8 with multiple sclerosis, 6 with cerebellopontine angle tumor). Normal and pathological results are discussed and diagnostic prospects of this procedure evaluated.
