Coronavirus can cause problems with the ears, the researchers said. Specialists in hearing from the University of Manchester, who oversaw the patients with COVID-19, found that in a few weeks, about 13 percent of patients reported problems with hearing.
According to a UK study, the coronavirus can cause problems with hearing every eighth patient, reports the Daily Mail.
Audiologists from the University of Manchester tracked 121 adult patient who was admitted to the hospital Wythenshaw with the coronavirus.
On the question of re-hearing 16 people answered that their hearing has deteriorated eight weeks after discharge.
Eight patients reported hearing impairment, and eight reported that they suffer from ringing in the ears.
the Researchers noted that other viral diseases such as measles, mumps and meningitis, can also cause hearing loss.
Other coronaviruses, which are known to infect humans, can damage important nerves that carry information to the brain and from the brain.
Lead researcher Professor Kevin Munro says: “it is Theoretically possible that COVID-19 may cause problems with parts of the auditory system, including middle ear or the cochlea of the inner ear”.
the middle ear is a tube that leads from the eardrum to the auditory nerve and the throat. She walked past the cochlea, a hollow spiral bones are located in the inner ear, which plays a key role in hearing.
Professor Munro says: “for Example, auditory neuropathy, hearing disorder, in which the cochlea operates, but the transmission by the auditory nerve to the brain can be disrupted.”
in people with auditory neuropathy have trouble hearing when there is background noise, for example, in the pub.
a Condition called Guillain-Barre syndrome, is also associated with auditory neuropathy, which is also known to be linked to a coronavirus.
study Participants were asked about their hearing by telephone after discharge. Sixteen people (13.2%) reported that their hearing had become worse. Eight people reported hearing impairment, but four said that they already had some hearing problems before the coronavirus.
eight reported tinnitus (noise in the ears that is not caused by an external source), three of which already had pre-existing hearing loss.
the Results of a study published in the international journal of audiology, added to concerns that Covid-19 can have long-term consequences for hearing, especially for those who have problems.
it is Noteworthy that the average age of patients reported hearing problems was 64 years.
Scientists from the University of Manchester say that you want to do more research to�� to determine the cause of the virus with impaired hearing.
Professor Munro added: “While we are quite sure of the distinction previously existing and recent changes in hearing and tinnitus, we urge caution. It is possible that other factors besides COVID-19, can affect the already existing hearing loss and ringing in the ears. These can include stress and anxiety, and the use of face masks, which reduce communication used for the treatment of COVID-19 medicines that can damage the ear, or other factors associated with severe disease. That is why we believe that there is an urgent need for high-quality studies to investigate acute and temporary effects COVID-19 at the hearing, and audio-visual system.”
