[Neurootological findings in zoster oticus (author's transl)].

Zoster oticus is an important disorder in neurootological routine diagnostics. However, the neurotoxic zoster virus is not being confined to the nerval periphery. Therefore as well typical peripheral as well as typical central as well as combined reactional patterns are to be found by neurootological functions tests. By selection and adaptation of tests optimal diagnostics can be completed in the vestibular-ocular, the vestibular-spinal and retinal-ocular sensory motory systems. Thus disorders as such can be identified and additionally localised. The peripheral zoster oticus can be differentiated from the central zoster encephalitis. These findings are demonstrated by typical case reports.
