A novel aerosolisation mitigation device for endoscopic sinus and skull base surgery in the COVID-19 era.

ABSTRACT:

Purpose

To provide a novel solution to reduce aerosol exposure in the operating room during endoscopic sinus and skull base procedures in the COVID-19 era.

Methods

We have designed a 3D printable midfacial mask that partially seals the nose, while allowing instrumentation during endoscopic transnasal surgery. The mask when connected to a vacuum system creates a constant negative pressure inside it, sucking out aerosols and gases generated during surgical procedures. Its effectiveness was tested using vapour exhalations by a human volunteer and drilling bone in a head model. The physical barrier effect was measured using fluorescein atomization in a head model.

Results

The pressure and airflow measured remained negative inside it in all the different situations tested.
