[Preventive care and treatment of hearing problems in persons exposed to radiation]

Neurosensory hypoacusis (NSHA) was treated in 193 patients exposed to radiation consequently to the Chernobyl accident. The article describes changes observed in the examinees on audiograms, ECG, rheoencephalograms (REG) and acoustic evoked potentials. Treatment of patients with radiation-induced NSHA was aimed at normalization of tonicity of the cerebral vessels, venous outflow, pulse blood filling, arterial pressure, bioelectric activity of the brain, cardiac activity with account to hearing defects in different portions of the acoustic system. The treatment has improved parameters of tonal and speech audiometry, cortical acoustic evoked potentials, REG and EEG in 63.4% of the patients. The rest of the patients achieved stabilization of the process, arrest of progressive hearing loss. Also, positive effects were seen on the general condition of the patients, their working ability. The patients experienced relief of the headache, stuffy ears, noise in the ears, etc.
