Covid and the Ears

Recently, vertigo or dizziness has been described as one of the clinical manifestations and possible complications of COVID-19.

New research finds that cells in the ear are susceptible to infection with SARS-CoV-2, causing symptoms that include dizziness, ear ringing, and hearing loss. Experts say that other viruses may also cause hearing loss, and newborns can be especially at risk.

COVID-19 can evolve into a nervous system infection. The direct and indirect mechanisms of damage associated with SARS-CoV-2 neuropathogenesis could affect our sensory functionality, including hearing and balance.

Audio-vestibular consequences of COVID-19 are less reported compared to other symptoms of neurological involvement, such as gustatory or olfactory dysfunction, which have become key indicators aiding in the diagnosis of the infection. Among these disorders, the commonly reported presentation is that of vestibular neuronitis.

Patients who had been diagnosed with COVID-19 seem to be more likely to suffer from vertigo/dizziness and to compensate more slowly. COVID-19 infection may cause inner ear damage and lead to vestibular dysfunction.
