Audiovestibular Symptoms of Severe Acute Respiratory Syndrome Coronavirus-2 Infection.

Abstract

Dear Editor, We would like to correspond on the publication “Shortand Long-Term Self-Reported Audiovestibular Symptoms of SARS-CoV-2 Infection in Hospitalized and Nonhospitalized Patients” [Almishaal and Alrushaidan, 2022]. According to an auditory inquiry research conducted by Almishaal et al. [2022], audiovestibular symptoms are common among SARSCoV-2-infected people during the acute phase of the disease. These symptoms, on the other hand, are usually temporary and vanish within the first 2 weeks of infection [Almishaal and Alrushaidan, 2022]. We agree that the COVID-19 vaccine has the potential to cause hearing loss. The incidence of both shortand longterm audiovestibular symptoms related to SARS-CoV2 infection was examined and published in the most recent paper by Almishaal and Alrushaidan [2022]. Aural fullness, tinnitus, and hearing loss were just a few of the good findings mentioned by Almishaal and Alrushaidan [2022]. In the serious COVID-19 instances, the symptoms were more prevalent. Since its debut, COVID-19 has been linked to abnormal auditory impairment [Sriwijitalai and Wiwanitkit, 2020]. However, the exact hearing problems associated with COVID-19 are still unknown. The most recent publication by Almishaal and Alrushaidan [2022] may corroborate the existence of a problem with COVID19, but the findings are primarily based on patient selfreports, a subjective complaint that may need to be confirmed for dependability. However, the discovery that the clinical symptoms are largely transient and completely recovered spontaneously during the first 2 weeks postinfection may provide some insight into its pathophysiological mechanism. The clinical problem’s transient existence and swift removal following infection recovery may support the hypothesis that symptoms and infection are related. Hyperviscosity has been proposed as an underlying cause for sudden hearing loss [Mösges et al., 2009]. COVID-19 has been associated to high blood viscosity and hearing loss is a possible consequence [Joob and Wiwanitkit, 2021]. When COVID-19 improved, blood viscosity decreased, which could explain why auditory impairment selfresolved over time. Because the work is entirely based on clinical investigation, the work by Almishaal and Alrushaidan [2022] mentioned in the letter can be expanded upon using other works. Additional research on patient data will aid in better understanding of the problem. Similarly, the work by Sriwijitalai and Wiwanitkit [2020] on “abnormal auditory impairment” in 2020 is too early in terms of publication year and pandemic period to conclude the
