[The relationship between the condition of the brain stem compartments of the acoustic analyzer and rheoencephalography in people who participated in the liquidation of the consequences of the Chernobyl' nuclear plant disaster].
Pure-tone and speech threshold and suprathreshold audiometry, short-latent acoustic evoked potentials (SLAEP) and rheoencephalography (REG) were applied in examination of 67 patients with neurosensory hypoacusis (NSH) aged 21 to 45 years. These patients worked as wreckers in the zone contaminated with radionuclides 5 years and later after the Chernobyl accident. Relationships between functional condition of the truncal structures of the acoustic analyser and cerebral hemodynamics were studied. Correlation analysis has shown that there is close correlation between SLAEP and REG, especially in the vertebrobasillar area of cerebral circulation. The closest relations existed between the duration of the latent period of SLAEP wave V, interpeak interval I-V and rheographic index in the vertebrobasillar system. Combination of SLAEP and REG potentialities opens wide prospects for revelation of the key pathogenetic links for disorders of the acoustic system of unconventional origin, improves quality of these disorders diagnosis, promotes individual approach to therapy of such patients.
