AnResearch suggests that inner ear infection could be a significant cause for COVID-19-associated balance and hearing problems.
InA new study was published in the journal last month. Nature Communications MedicineAccording to the U.S.-based study authors, they wrote that they studied human inner ear tissues, human inner and in vitro cell models, and mouse inner ears tissue to reach their conclusions.
GROWING Evidence LINKs COVID-19, HEARING Loss, RESEARCHERS SAY
ObservingThe researchers discovered a pattern in the inner ear infection that was consistent with the symptoms of 10 COVID-19 patients suffering from ear-related symptoms such as hearing loss, vestibular dysfunction, and tinnitus. They also developed the first human cell models of infectious inner ears disease.
UsingIt is hard to find adult human inner ears tissue. The researchers found that both mouse and human inner ears cells possess the “molecular machinery” necessary for SARS-CoV-2 entry.
TheAccording to experts, virus could either enter the ears via the eustachian tub, which connects the nose and middle ear, or escape through small openings around the olfactory nervous system.

StankovicMIT interviewed a co-author of the study: MIT’s Judith Sullivan NewsIt is possible for the virus to enter the brain space and infect the cranial nerves that connect to the inner ear.
FurthermoreThe researchers suggested that the infection could infect hair cells. SchwannConfocal microscopy allows you to see cells within the inner ear.
CORONAVIRUS IS CONSIDERING TINNITUS RISK, STUDY SUGGESTIONS
“Our”These findings indicate that inner ear infections may be a significant cause for COVID-19-associated hearing and balance problems,” they wrote.
StillThe overall percentage of COVID-19 patients suffering from ear-related problems is unknown.
“InitiallyBecause routine testing was not available for patients diagnosed with this condition, it was difficult to perform routine testing. [COVID-19], and also, when patients were having more life-threatening complications, they weren’t paying much attention to whether their hearing was reduced or whether they had tinnitus,” Stankovic said.
“WeWe don’t yet know the exact incidence, but our findings suggest that we should pay more attention to audiovestibular symptoms among people with hearing loss. [COVID-19]She also noted the importance of exposure.
StankovicThe outlet was informed that researchers are now looking to use human cell models to test treatments for inner ear infections due to COVID-19.
