Quantification and visualization of aerosols in ear, nose, and throat exam and flexible laryngoscopy.

ABSTRACT:

Objective

To measure and visualize aerosol generation during ear, nose, and throat (ENT) exam and flexible laryngoscopy, as safety recommendations are currently to defer routine and low-priority examinations.

Methods

Aerosols generated during ENT examination and flexible laryngoscopy were quantified by laser aerosol spectrometry and visualized live by high-speed imaging during those procedures for three participants who were tested three times for each test.

Results

Routine ENT examination and flexible laryngoscopy produce aerosols at levels comparable to normal breathing and speech.

Conclusion

During ENT examination and flexible laryngoscopy, the practitioner should wear a surgical mask and potentially contaminated surfaces should be cleaned after the procedur
