[The role of neurovisualization methods in diagnosis and verification of vertigo etiology].

Roentgen computed tomography (RCT) and MR-imaging (MRI) were used in investigation of vertigo etiology and affection of the cochleovestibular analyzer in 130 patients aged 28 to 74 years with recurrent systemic rotatory vertigo or its other symptoms. All the patients have undergone comprehensive otoneurological examination, RCT and MRI which showed that peripheral cochleovestibular syndromes (PCVS) caused by arterial hypertension (AH), atherosclerosis (AS), vascular dystonia (VD) are rarely characterized by focal alterations in the brain. PCVS comparison with blood flow in the vertebral arteries (VA) detected most frequently anomalies and asymmetries of the diameters. MR-angiography plays an important role in verification of pathology of intracranial VA. In central cochleovestibular syndrome (CCVS) with AH, AS, VD, principal pathological changes were registered in the brain trunk and cerebellum by MRI. Vestibulometry and otoneurological method detect not only vascular cochleovestibular peripheral and central syndromes but also to make differential diagnosis. RCT and MRI verify cochleovestibular syndromes in patients with multiple encephalomyelitis, VIII nerve neurinoma and tumors of the posterior cranial fossa.

[Vertigo and peripheral ischemic cochleovestibular syndrome caused by circulatory insufficiency in the vertebrobasilar system].

We studied characteristics of vestibular and acoustic disorders in patients with arterial hypertension, atherosclerosis and vascular dystonia; correlation between peripheral cochleovestibular syndromes (PCVS) and circulation in the major and intracranial arteries, central hemodynamics, organic changes in the brain. We discovered that anomalies and asymmetry in vertebral arteries diameters, stenoses, reduced stroke and minute blood volumes play an essential role in development of PCVS. The latter are rarely accompanied with ischemic foci in the brain. Medication of vascular vertigo consists in administration of an adequate drug. We believe that betaserk is most effective.

[Vestibular cochlear disturbances in multiple sclerosis].

To specify the character of vestibular cochlear disturbances in multiple sclerosis (MS) and mechanisms of their formation, the objective quantitative evaluation of experimental caloric nystagmus using the computer electronystagmographic method and a comparison of hearing impairment with asymmetry of vestibular reactions were conducted in 48 patients with MS. The peculiarities of vestibular disturbance found in the study suggest a predominance of central vestibular syndrome with both subtentorial and supratentorial traits. The influence of the heat stimulus of vestibular analyzer (hot water caloric test) in multiple sclerosis revealed during computer electronystagmography may have diagnostic value.

[The role of audiological methods of investigation in diagnosis and treatment of chemodectomas and hemangiomas of the middle ear].

Diagnostic value of some audiological methods of investigation (pure-tone audiometry, tympanometry, noisimetry) has been determined on the basis of examination and treatment of 114 patients with chemodectoma and hemangioma of the middle ear. Tympanometric evidence directly correlated with primary location and dissemination of the tumor. Changes on tympanograms and noisimetries correlate with the results of the tests with pressure of the neck's vessels and elevation of airpressure in the external acoustic meatus. Audiological findings are comparable with those of CT and MRT of the temporal bones and visualization of the tumor in surgery. High significance of the above methods was proved.
