Abstract

Introduction: The otorhinolaryngologist, in many situations, is the first health professional to assist the patient with covid-19, given the high frequency of symptoms involving the specialty, since the viral condition is transmitted through the respiratory tract by aerosols. Common symptoms include changes in smell and taste, sore throat, dry cough, deafness, vertigo, recurrent ear infections and vertigo. Vocal symptoms during or after coronavirus infection have also been reported, whose prevalence and course are not yet well determined. The endoscopic reports record changes in the vocal folds such as edema, polypoid lesions, paralysis, glottic gaps, dysmotility and stenoses. In pathophysiology, the direct viral action or secondary to pulmonary, neurological and psycho-emotional impairment is discussed.Objective: To carry out a detailed descriptive review on the topic "dysphonia and covid-19" in order to gather in a single document the studies available in the literature and alert specialists to these symptoms associated with the virus. .Methodology: A literature review will be carried out in the databases: Web of Science, PubMed, Google Scholar, and Scopus, from 2020 to April 2023. Scientific terms used in searches: [COVID-19 AND Dysphonia] OR [SARS -CoV-2AND Voice disorder] OR [ Vocal cord AND covid-19] OR [Vocal fold AND COVID-19] OR [Vocal fold disfunction AND COVID-19] OR [Vocal cord paralysis AND COVID-19] OR [Larynx Disease AND COVID-19] OR [ Vocal fold paralysis AND COVID-19] OR [Vocal Fold palsy AND COVID-19]. All study types will be included, except review studies. Data analyzed: age, gender, ethnicity, number of patients, time since diagnosis, vocal symptoms, associated symptoms, course of symptoms, hospitalization, ICU stay, tracheotomy, videolaryngoscopy findings.
