There are a number of causes for this sudden hearing loss including genetic factors, age and medical conditions including bacteria meningitis, diabetes, particular viruses and severe inflammation of the ear.
We’ve covered Sudden Sensorineural Hearing Loss in our blog post on How To Protect Your Hearing During Cold And Flu Season.
Now data from the first 12 months of the COVID-19 pandemic has revealed that one of the after effects of the virus is SSHL and/or tinnitus.
It is still unclear how common or likely this condition will present in those who have had the COVID-19, or the role other contributing health factors play that would exacerbate the risk of hearing loss.
More information is needed and research is on-going.
Symptoms of SSHL are many and may include:
If you have any of these symptoms occur suddenly, don’t delay. Make an appointment to see your doctor as soon as possible. Your doctor will be able to confirm a diagnosis and recommend a course of treatment.

Kevin Munro, professor of audiology at the University of Manchester said his team is investigating the prevalence and causes of such problems, noting it is unclear whether they are down to the virus itself, the immune system response, stress, or even treatments for COVID – or whether it could simply be that hearing problems become apparent in a noisy hospital where individuals wear masks.
“I think there’s likely to be lots of explanations for why people were reporting problems,” he said.
Time is of the essence. Go straight to your doctor for an accurate diagnosis.
Your doctor may prescribe steroids which have been shown to significantly improve the recovery of hearing by reducing inflammation and swelling of the cochlea.
And with early intervention, experts have found that in 50% of cases, hearing can spontaneously recover within a couple of weeks, but if this does not occur, the loss can be permanent. If that is the case, hearing aids may be an option to improve hearing. Those with severe permanent loss have been fitted with cochlear implants.
The information below is current as of 21 Septmber 2021.
Some people have reported the onset of tinnitus after receiving a COVID vaccine.
According to American media, the tinnitus reports account come from one out of every 21,000 people vaccinated. The vaccine in question appears to be the Johnson & Johnson (marketed as Janssen). The European Medicines Agency released a safety update on September 8, recommending that tinnitus 'should be added as a side effect of COVID-19 Vaccine Janssen; the frequency has been estimated as rare'.
Experts express caution as to whether the link between COVID vaccines is causal or coincidental but it is worth noting that some commonly prescribed medications have ototoxicity - that is, they may affect your hearing.
