Objective: Although the most common symptoms of Covid-19 are otolaryngological symptoms including cough, sore throat, shortness of breath, loss of sense of smell and taste, reports of autologous and audiological manifestations of the disease such as hearing loss, tinnitus, dizziness and. .. There is also. The present study reviews existing studies to investigate the occurrence of hearing loss, its types and possible causes in patients with Covid-19.
Studies show that the risk of transient hearing loss, sensory neurosis, and sudden deafness increases following Covid-19. Upper respiratory tract infection, followed by acute otitis media, can be a major cause of transient hearing loss in people with Covid-19. Regarding the causes of sensorineural hearing loss and sudden deafness, various reasons such as direct viral damage to peripheral organs, vascular disorders, and the use of autotoxic drugs used in the treatment of the disease have been cited.
Because persistent hearing loss has devastating effects on quality of life, early detection of hearing loss and early intervention are essential. According to the available reports, it seems that hearing loss can be one of the complications of Covid-19, but due to the lack of sufficient evidence and heterogeneity among the existing studies, this issue can still not be stated with certainty. Therefore, longitudinal studies on a larger number of patients using appropriate assessment tools are recommended.
