CONCLUSIONS: As global ENT services resume routine elective operating, we demonstrate the potential use of a simple negative pressure mask technique to reduce the risk of viral exposure for the operator and theatre staff during ESS. A few studies have sought to investigate this concern in a simulated setting and have demonstrated significant droplet spread during endoscopic sinus surgery, particularly when using powered drills 15, 16 . This proof of concept study demonstrates that a negative pressure mask can effectively reduce both fine droplet nuclei aerosol and larger droplet spread during endoscopic sinus surgery using powered instruments. This study demonstrates the effectiveness of a simple negative pressure mask in reducing droplets and respiratory nuclei generated during endoscopic sinus surgery, thus reducing potential exposure for both operator and theatre staff.	./cache/cord-334166-vll4s0xq.txt	./txt/cord-334166-vll4s0xq.txt
