A cascade impactor placed adjacent to the nares collected generated particles with aerodynamic diameters \u226414.1\u2009\u00b5m. The 3D printed models and syringes were used to simulate middle and external ear suctioning as well as open suctioning, respectively. Provider\u2019s personal protective equipment (PPE) and procedural field contamination were also recorded for all trials using vitamin B2 fluorescent tracer.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The positive controls of nebulized vitamin B2 produced aerosol particles \u22643.30\u2009\u00b5m and endonasal drilling of a 3D model generated particles \u226414.1\u2009\u00b5m. As compared with positive controls, aerosols and small droplets with aerodynamic diameter \u226414.1\u2009\u00b5m were not detected during rigid nasal endoscopy, flexible fiberoptic laryngoscopy, and rigid nasal suction of cadavers with simulated breathing. There was minimal to no field contamination in all 3 scenarios. Middle and external ear suctioning and open container suctioning did not result in any detectable droplet contamination. The clinic suction unit contained all fluorescent material without surrounding environmental contamination.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>While patients\u2019 coughing and sneezing may create a baseline risk for providers, this study demonstrates that nasal endoscopy, flexible laryngoscopy, and suctioning inherently do not pose an additional risk in terms of aerosol and small droplet generation.
