“…The contamination extended for over 2 m from the drill site, which is further than previously reported spread (~1 m) during simulated mastoid drilling. 4,14 The extended reach of contamination in the present study may be attributable to the use of a fluorescent dye as irrigation fluid rather than impregnation into bone. 4 The extent of drilling-induced contamination was substantially reduced with use of the drape tent 9 (Fig.…”

“…3 COVID-19 is thought to spread not only via droplets, but also through contamination of mucous membranes around the eye during aerosol-generating medical procedures (AGMPs). 3,4 A substantial number of otolaryngology procedures, including mastoidectomy, are considered aerosol generating, 5 and early reports from China and Italy indicate high rates of infection amongst otolaryngologists. [6][7][8] The present study aimed to 1) measure the extent of droplet contamination during mastoid drilling in a preclinical model both with and without a novel commercially designed drape to create a tent over the surgical field, and 2) evaluate various PPE options including a full-face respirator, a modified full-face snorkel mask, and safety goggles or spoggles (foam-lined safety goggles) and a half-face mask.…”

“…Novel draping techniques, such as the 'double-drape' system, have also been suggested in order to reduce droplet spray. 2,7,8 In addition, bespoke surgical shields that attach to the microscope may afford some protection to the surgeon. Sealed, low-profile goggles could potentially provide adequate eye protection with a minimal increase in eye-microscope distance.…”

“…1 Mastoidectomy, which utilises high-speed drills within the mastoid air cells, is therefore considered to be an aerosolgenerating procedure; the plume of potentially virus-containing aerosol generated by the drill may pose a risk to the surgeon and operating theatre staff. [2][3][4] The UK government and specialist healthcare bodies currently recommend the use of personal protective equipment (PPE) for all surgery involving the use of high-speed drills. 5,6 This includes, as a minimum, fluid-resistant long-sleeved gowns, gloves, filtering facepiece code 3 (FFP3) respirator masks, and eye and face protection.…”

“…The latter are associated with a higher risk of infection. 5,12,13 While available evidence suggests that the transmission of SARS-CoV-2 is primarily through respiratory droplets and fomites, there is no consensus. Little research is available on the risk of specific otolaryngological procedures, and conflicting information persists among regulatory bodies as to the degree of protection required for AGPs.…”
