Application of a Modified Endoscopy Face Mask for Flexible Laryngoscopy During the COVID-19 Pandemic.

Diagnostic flexible laryngoscopy (DFL) is a critical tool in the armamentarium of an otolaryngologist. However, in the midst of the COVID-19 pandemic, DFL represents a high-risk procedure for patients and otolaryngologists due to the risk of aerosolization. In cases where DFL is required, in patients with COVID-19 positivity or unknown COVID-19 status, we describe the use of a modified endoscopy face mask as an adjunct to personal protection equipment to reduce occupational transmission of COVID-19 while performing DFL. Our modified endoscopy mask provides an additional barrier against the transmission of airborne pathogens. The modified endoscopy face mask may also serve as a useful tool for otolaryngologists as they return to performing more aerosol-generating procedures in the outpatient setting.
