BACKGROUND: The coronavirus disease (COVID-19) pandemic has raised concern of
transmission of infectious organisms through aerosols formation in endonasal and
transoral surgery. METHODS: Retrospective review. We introduce the
negative-pressure otolaryngology viral isolation drape (NOVID) system to reduce
the risk of aerosol. NOVID consists of a plastic drape suspended above the
patient's head and surgical field with a smoke evacuator suction placed inside
the chamber. RESULTS: Four patients underwent endonasal (4) and endo-oral surgery
(1). Fluorescein was applied to the surgical field. Black light examination of
fluorescein-treated operative fields revealed minimal contamination distant to
the surgical field. In two prolonged cases with high-speed drilling, droplets
were identified under the barrier and on the tip of the smoke evacuator.
Instruments and cottonoids appeared to be a greater contributor to field
contamination. CONCLUSIONS: Negative-pressure aspiration of air under a chamber
barrier, which appears to successfully keep aerosol and droplet contamination to
a minimum.
