Hearing loss may be caused by certain viral infections. The hearing loss due to viral infection can be congenital or acquired, bilateral or unilateral. The viral infections typically cause sensorineural hearing loss (SNHL), although conductive or mixed hearing loss can be found. The corona virus disease 2019 (COVID-19) infection has deleterious impact on the cochlear hair cells. The hearing loss will not improve even patient recovered from COVID-19 infections. This is probably a neuro-auditory involvement in COVID-19 infections. The current COVID-19 is caused by severe acute respiratory syndrome corona virus 2. The audiologic and radiologic investigations are helpful for evaluation of the hearing loss in COVID-19 patients. Hearing loss due to COVID-19 infections is rarely reported in medical literature so far. Hearing loss specifically SNHL is often challenging to the clinicians in this current pandemic. The mechanism for this deleterious effect on the cochlear hair cells requires further research. There is a large gap in the understanding of the etiopathogenesis, epidemiology, and clinical presentations such as hearing loss and human transmission of this disease. There should be a continuous monitoring of the hearing loss and tracing of this COVID-19 infection is needed to ensure the detail understanding of this inner ear pathogenesis. This review article provides an overview of COVID-19 infections and its impact on hearing loss.
