The research was carried out with the team removing the mastoids from the deceased patients’ bodies and taking specimens from their middle ears. Mastoid specimens from two patients tested positive for SARS-CoV-2 .
‘Two of the 3 patients tested positive for SARS-CoV-2 virus in the mastoid or middle ear, with viral isolation from 2 of 6 mastoids and 3 of 6 middle ears.
Results for case 1 were positive for the right middle ear only. Case 2 had negative results for all samples,’ the study stated.
‘This study confirms the presence of SARS-CoV-2 virus in the middle ear and mastoid, with significant implications for otolaryngology procedures,’ it added.
The team calls for taking proper precautions to stop the spread of infection in patients visiting hospitals or during surgical procedures.
‘Droplet precautions (including eye protection and proper N95 level mask) are warranted for outpatient procedures involving the middle ear due to proximity to these potentially infectious spaces. Given the high asymptomatic rate of Covid-19 cases, caution is warranted for all elective ear surgery, and negative status by testing is indicated,’ the study stated.
