A recent study by Johns Hopkins researchers published in JAMA Otolaryngology—Head & Neck Surgery found evidence of SARS-CoV-2— the virus that causes COVID-19—in the middle ear and mastoid of two patients diagnosed with COVID-19. A summary of the study was published in an article appearing on MedPage Today.
Warning that the results have “significant implications for otolaryngology procedures,” the authors of the study recommend personal protective equipment (PPE) such as eye protection and N95 masks be worn by health care practitioners performing ear surgery. In an accompanying editorial titled “News Flash,” Bradley Kesser, MD, of the University of Virginia in Charlottesville, said that otolaryngologists have been waiting six months for this study, ”given the anatomic connection from the nasopharynx, site of initial infection and virus isolation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to the tympanic cavity through the eustachian tube.” Kesser goes on to say that although no documented cases of SARS-CoV-2 infection have resulted in a health care worker due to a middle ear or mastoid procedure, “mastoidectomy clearly generates aerosols and exposes health care workers,” and proper precautions should be followed. Kessler recommends pre-screening several days prior to the procedure and in-office screening, the day of.
