[Cervical vertebra-induced hearing and equilibrium disorders. Recent clinical aspects].

The contribution of cervical spine disorders to cochleovestibular symptoms was based on the evaluation of patients complaining of dizziness and/or inner ear hearing loss, treated in the ENT Department of Tubingen University between 1977 and 1982. Cervicogenic vertigo was provoked by movements of the cervical spine, but the latter rarely caused tinnitus and never induced hearing loss. The diagnosis between a vascular or proprioceptive nystagmus may be made on the presence of lesions of the cervical spine. These are disorders of the cranio-cervical or the thoraco-cervical region especially and much less often due to osteochondrosis of the vertebrae. The findings of a cervical osteochondrosis has no diagnostic value unless vertigo is provoked by head movements. In cervical vertigo the thoraco-cervical region should be examined to prove a thoracic outlet syndrome. In selected cases operative treatment is possible, eg. transoral resection of the dental process of the axis, resection of the posterior arch of the atlas, myotomy of the anterior scalenus muscle or decompression of the vertebral artery.
