This study aims to provide a greater understanding of particle generation and exposure risk during endoscopic endonasal instrumentation. STUDY DESIGN: Prospective quantification of aerosol generation during office-based nasal endoscopy procedures. METHODS: Using an optical particle sizer, airborne particles concentrations 0.3 to 10 microns in diameter, were measured during 30 nasal endoscopies in the clinic setting. Measurements were taken at time points throughout diagnostic and debridement endoscopies and compared to preprocedure and empty room particle concentrations. RESULTS: No significant change in airborne particle concentrations was measured during diagnostic nasal endoscopies in patients without the need for debridement. However, significant increases in mean particle concentration compared to preprocedure levels were measured during cold instrumentation at 2,462 particles/foot(3) (95% CI 837 to 4,088; P = .005) and during suction use at 2,973 particle/foot(3) (95% CI 1,419 to 4,529; P = .001). In total, 99.2% of all measured particles were </=1 mum in diameter. CONCLUSION: When measured with an optical particle sizer, diagnostic nasal endoscopy with a rigid endoscope is not associated with increased particle aerosolization in patient for whom sinonasal debridement is not needed. In patients needing sinonasal debridement, endonasal cold and suction instrumentation were associated with increased particle aerosolization, with a trend observed during endoscope use prior to tissue manipulation. Endonasal debridement may potentially pose a higher risk for aerosolization and SARS-CoV-2 transmission. Appropriate personal protective equipment use and patient screening are recommended for all office-based endonasal procedures. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:E1415-E1421, 2021.
