title: [Cerebellopontile angle lesion syndrome in circulatory disorders in the vertebral-basilar basin].
abstract: Numerous observations of patients with the syndrome of cerebellopontile angle affection carried out with the use of the otoneurological method make it possible to specify a characteristic syndrome pointing to the vascular genesis. In such cases typical for the clinical picture were noise in the ears, progressing hardness of hearing, vestibular paroxysms, and symptoms charasteristic of involvement of the cerebellopontile angle revealed at neurological and otoneurological examinations. Along with the symptoms characteristic of impairment of the inner ear receptors these patients showed disturbances of the mechanism of experimental vestibular reactions, spontaneous nystagmus persisting after vestibular paroxysms for some months and sometimes years; a lowering of the sensitivity of the nasal and oral mucosa on the side of the affected ear, disturbances of taste on onehalf of the tongue, disorders of coordination and statics, olfactory disturbances of the trigeminal character. Observations of 84 patients (36 males and 48 females) aged from 40 to 59 years were analyzed in detail. The observations lasted from 4 months to 12 years. Some patients were admitted to the clinic with the diagnosis of "neurinoma of the VIIIth nerve". Detailed neurological examinations carried out in combination with other additional diagnostic methods made it possible to rule out that diagnosis: the process (of the same localization) was found to be of vascular character. Long-term catamnesis and positive effects of pathogenetic therapy have shown that it is reasonable to regard the syndrome of the cerebellopontile angle affection in dyscirculatory disturbances of the vertebrobasilar system as a disease entity.
