But after all this, what is tinnitus ? This is how nuisances such as buzzing or murmuring in the ears are known. These are only heard by those affected and have no explanation based on the external environment.
The investigation analyzed 10 cases of patients who had COVID. Subsequently people had tinnitus. Analysts consider that the virus could affect the cells of the inner ear and therefore present this sequel.
To investigate the causal relationship between SARS-CoV-2 and audiovestibular dysfunction, they examined human inner ear tissue, in vitro cell models of the organ, and mouse ear tissue.
The study does not confirm a direct causal relationship, but there may be a connection.
”None of our patients had evidence of middle ear infection on otological examination or radiological imaging, whereas all patients had direct viral infection or inflammation of the inner ear and cochleovestibular nerve on analysis and this may be the cause of the discomfort,” the report explained.
