title: Peripheral vestibular disorder of cervical origin.
abstract: The provoking mechanism of peripheral vestibular disorder in the cervicovestibular syndrome is discussed on the basis of the results of perivascular sympathectomy of the vertebral artery. The peripheral type of this syndrome can be differentiated from the central type in that it shows fatigue due to positioning nystagmus and the reversion phenomenon in the self-recording cupulogram. 42 cases of the peripheral type could be completely cured of episodes of vertigo by the unilateral operation, but the other 6 cases required bilateral operations to prevent such episodes.
