|Workman et al. 2020 ||Experimental study||N/A||N/A||Cadavers||1. Visual inspection of number of fluorescein droplets generated by nasal endoscopy, endonasal surgery with and without microdebrider and high-speed drill.|
2. Visual inspection of number of fluorescein droplets, generated by atomizer placed posterior to the internal valve (droplet size 30-100um) to simulate cough/sneeze.
|1. Nasal endoscopy and cold non-powered endonasal procedures do not exhibit any features of AGMPs and has a lower risk of aerosol generation.|
2. Droplet spread up to 66 cm from the nare, with peak density around 30 cm. (Modified) surgical masks were able to reduce the droplet spread.
