FIG. 1.

Aerosolization of fluorescent bone dust and droplets occurs during mastoidectomy. A, The aerosol plume created by using a high-speed otologic drill to perform a cortical mastoidectomy is visible in a darkened room under ultraviolet light. Surgeon is using a size 6 cutting bur, at 70,000 RPM, on a cadaveric specimen. See Supplemental Video 1 {Aerosolization of fluorescent droplets and bone particulate from cortical mastoidectomy is demonstrated on a cadaveric specimen under an ultraviolet light in a darkened room. The OtoTent preparation and use with the microscope is shown.}. B, Fluorescent debris (some indicated by green arrowheads) soiling a surgeon's chest, arms, and lap is shown under ultraviolet light after drilling part of a cortical mastoidectomy for 2 minutes, with size 6 cutting bur, at 70,000 RPM. C, Image showing fluorescent particulate matter scattered on the surgeon's face shield and hair covering (green arrowheads) after 2 minutes of drilling.
