Mastoid and temporal bone surgery
The mastoid and middle ear mucosa may carry the same risk of viral aerosolization as sinus and nasal surgery due to the connection with the nasopharynx through the Eustachian tube. At a minimum, N95 mask is required for mastoid surgery. PAPR is required for the surgeon and OR staff in patients with SARS-CoV-2 positive status, and this equipment can interfere with the use of an operative microscope. Using an exoscope is an alternative, but this equipment might not be widely available.
