Workman et al. 2020 [13]Experimental studyN/AN/ACadaversVisual inspection of number of fluorescein droplets generated by nasal endoscopy, endonasal surgery with and without microdebrider and high-speed drillHigh-speed drill can generate high airflow velocities and aerosolization. Nasal endoscopy and endonasal procedures, including the use of microdebrider do not exhibit any features of AGMPs and has a lower risk of aerosol generationIndirect
