Covid-19 impact on vocal and laryngeal sequelae: a literature review.

SARS-CoV-2 disease is a new nosological entity with multiple repercussions on several anatomical districts. Many researchers have focused not only on lung damage but also on the laryngeal sequelae of the Covid-19 infection. To collate this information, this review analysed the literature published between March 2020 and May 2021. The findings seem to positively correlate Covid-19 and infection-related dysphonia, post- viral vagal neuropathy, inflammation and laryngeal oedema caused by cough and vomiting, and lesions of the vocal cords due to endotracheal intubation and tracheotomy. From analysis of the data, it is clear that ENT specialists and speech and language pathologists (SLP) will play a crucial role in the detection of dysphonia onset in patients reporting a previous Covid-19 infection. Further studies to assess the incidence and characteristics of dysphonia resulting from this disease are essential.
