OBJECTIVE: To study the effectiveness of auditory training using virtual reality technologies in people with chronic sensorineural hearing loss in dynamics. MATERIAL AND METHODS: The study included 68 patients aged from 24 to 97 years (mean age 57.63±15.87 years) with latent hearing loss (hearing loss at high frequencies), I degree of hearing loss and its variations. Auditory training was carried out on the basis of the Diagnostic and Rehabilitation System for spatial and speech hearing based on virtual reality using various audiovisual scenarios ReviAudio and control of speech perception, spatial hearing and hearing quality using the SSQRus questionnaire. RESULTS: A comparative analysis of the training results using the ReviAudio software revealed positive trends in the patient's response time and the patient's accuracy in determining the direction of the target signal, regardless of the symmetry and asymmetry of hearing loss. Patients with asymmetric hearing impairment observe an improvement in spatial hearing parameters, patients with symmetric hearing loss - speech perception and hearing quality, patients with latent hearing loss report an improvement in the quality of hearing. The auditory training is effective in individuals with mild chronic sensorineural hearing loss and in individuals with latent hearing loss as an adjunctive treatment.

[Audiological profile of patients with SARS-Co-V-2 PCR-positive cases]. / Audiologicheskii profil' patsientov pri zabolevanii, vyzvannom virusom SARS-CoV-2.

COVID-19 is a new pandemic caused by a novel coronavirus, SARS-CoV-2. COVID-19 has spread throughout China and received worldwide attention. On 11 February 2020, World Health Organization (WHO) officially declared COVID-19. The clinical symptoms of COVID-19 patients may vary, more often include symptoms affected by upper and lower respiratory tract damage. In ENT practice it is used to mention rhinitis, sore throat, anosmia/hyposmia. The effect of COVID-19 is an interesting issue in audiology. There were 78 patients who were confirmed positive for COVID-19 PCR-positive cases and 30 normal non-infected subjects in our study. The patients were divided into two groups according to severity their clinical symptoms from asymptomatic COVID-19 PCR-positive cases to severe form. All patients underwent audiological evaluation included tympanometry, acoustic threshold and transient evoked otoacoustic emission (TEOAE). Although hearing sensitivity was normal among some participants, it was statistically proved that TEOAEs could pick up subtle deterioration in the outer hair cells functions and impact on the cochlear.

[The psychogenic hearing disorders in the children and adolescents]. / Psikhogennoe narushenie slukha u detei i podrostkov.

The psychogenic loss of hearing is characterized by its impairment in the absence of anatomically and physiologically significant changes. These disorders are poorly represented in the scientific literature in comparison with the organic lesions. They are especially frequently overlooked in the children and adolescents. The objective of the present review was to analyze the literature publications concerning this problem and to report two clinical observations of the pathology in question. It is concluded that the clinically significant discrepancy between the audiological symptoms and the results obtained by the objective methods for hearing evaluation should be interpreted with great caution and raise the suspicion of the disease. The diagnosis and the identification of the involved psychogenic factors are of utmost importance for the success of the treatment.
