ABSTRACT

OBJECTIVE: To evaluate the features of voice disorders associated with novel coronavirus infection and to develop the clinical algorithm for diagnostic and treatment these patients. MATERIAL AND METHODS: A prospective observational study was conducted in patients with dysphonia after COVID-19 (n=60). All patients underwent a comprehensive voice assessment before and after the proposed treatment. The follow-up period was 1 month. RESULTS: Functional dysphonia or aphonia with a stable (refractory) or recurrent course was diagnosed in 58 (97%) patients. A tendency to an increase in the value of the latent period of the P300 and MMN in patients with voice disorder was revealed. There was a significant decrease in supraglottic constriction and glottal insufficiency before and after the treatment. The mean VHI-10 decreased from 25.4 before treatment to 15.3 after treatment. The DSI which is based on the set of voice measurements, statistically significant improved from -5.2 to 2.6 in patients as a result of treatment. The average value of MFI-20 improved from 65.4 (8.7) at the beginning of the study to 20.3 (5.3) after treatment. CONCLUSION: In patients with dysphonia or aphonia associated with COVID-19 are indicated a refractory type of dysphonia. This was indicated by the study of AEPs of the brain. The clinical algorithm for treatment and diagnostic patients with voice disorders after COVID-19 has been developed. The treatment of this group of patients should be adjunct by the drug therapy, kinesiotaping method and psychotherapy.
