Aerosol generation during cadaveric simulation of otologic surgery and live cochlear implantation
Abstract Objective The risk of SARS‐CoV‐2 transmission to healthcare workers through airborne aerosolization during otologic surgery has not been characterized. The objective of this study was to describe and quantify the aerosol generation during common otologic procedures in both cadaveric surgica...

Abstract Objective The risk of SARS‐CoV‐2 transmission to healthcare workers through airborne aerosolization during otologic surgery has not been characterized. The objective of this study was to describe and quantify the aerosol generation during common otologic procedures in both cadaveric surgical simulation and live patient surgery. Methods The number concentrations of generated aerosols in the particle size range of 0.30 to 10.0 μm were quantified using an optical particle sizer during both a cadaveric simulation of routine otologic procedures as well as cochlear implant surgery on live patients in the operating room. Results In the cadaveric simulation, temporalis fascia graft harvest using cold techniques (without electrocautery) (n = 4) did not generate aerosols above baseline concentrations. Tympanoplasty (n = 3) and mastoidectomy (n = 3) both produced statistically significant increases in concentrations of aerosols (P < 0.05), predominantly submicron particles (< 1.0 μm).
