A recent study published in the American Journal of Otolaryngology has shed light on a concerning discovery: SARS-CoV-2, the virus responsible for Covid-19, may linger in the middle ear for up to a month following infection, potentially contributing to the development of Otitis Media with Effusion (OME).
OME, characterized by fluid accumulation in the middle ear, can lead to temporary hearing impairment and is commonly associated with colds, sore throats, or upper respiratory infections. While it primarily affects children aged 3 to 7 years, the study found a notable association between Covid-19 infection and the onset of OME in patients who experienced the Omicron variant.
Lead researcher Chengzhou Han from Wuxi Huishan District People’s Hospital in China emphasized the significance of the findings, stating, “Our study highlights the potential effects of Covid-19 on the middle ear, suggesting a link between SARS-CoV-2 and OME onset.” The detection of the virus in the middle ear nearly a month post-infection suggests a potential alteration in OME treatment strategies and a risk of recurrence, underscoring the need for heightened vigilance among otolaryngologists.
The study, conducted from January to June 2023, included 23 patients aged 32 to 84 years who presented with OME post-Omicron infection, with 21 exhibiting unilateral symptoms. Fluid accumulation was observed in 88.0% of ears, and SARS-CoV-2 was detected in 12% of samples, with cycle threshold values ranging between 25.65 and 33.30.
“Our research unveils compelling evidence pointing to the potential otological manifestation of OME in the aftermath of a Covid-19 infection,” the researchers noted. “These findings underscore a conceivable link between SARS-CoV-2 infection and the emergence of OME, emphasizing the diverse implications of the SARS-CoV-2 virus.”
The study underscores the need for continued research into the long-term effects of Covid-19 and its potential impact on various bodily systems, including the ears. As healthcare professionals remain vigilant, further investigations will be crucial in refining treatment strategies and mitigating the risk of complications associated with post-Covid recovery.
