Conclusion
Reducing fluid spread during surgery involving the upper aerodigestive tract in the COVID-19 era is important for the positive or indeterminate patient. We introduce the use of a negative pressure system which may be more efficacious than a simple barrier in minimizing droplet contamination. Our preliminary findings indicate regional containment of the fluorescein dye within the housing system and at the smoke evacuator port. We also identified other potential sources of field contamination from surgical fomites suggests gentle instrument movements and isolation of materials removed from the nasal cavity are important.
