Reducing potential aerosol generation in flexible nasolaryngoscopy: a
novel method
Abstract
Key Points: 1. Clinical areas where Fibreoptic nasoendoscopy (FNE) and
larygoscopy (FOL) are performed are high risk areas in the COVID-19 era
as they are potential aerosol generating procedures (AGP). 2. Barrier
protection remains the key to prevent transmission. This device is one
that patients can wear to reduce potential aerosol contamination of the
surroundings. 3. Seal can be verified and tested by the patient placing
a thumb over the filter. 4. This device is simple, reproduceable, easy
to use, economical and well tolerated. Full personal protection
equipment (PPE) is still advisable to be worn by the operator. 5. This
device may reduce potential aerosolisation and thus reduce the need to
allow air changes in clinic rooms, freeing up clinical resources.
