Author, year	Study Design	Level of Evidence	Subjects (n)	Study Groups	Study outcomes	Conclusion	Directness of evidence
Workman et al. 2020 [13]	Experimental study	N/A	N/A	Cadavers	Visual inspection of number of fluorescein droplets generated by nasal endoscopy, endonasal surgery with and without microdebrider and high-speed drill	High-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 generation	Indirect
