Endonasal instrumentation and aerosolization risk in the era of COVID‐19: simulation, literature review, and proposed mitigation strategies

Abstract

We confirm that aerosolization presents a risk to the endonasal skull base surgeon. In the outpatient setting, use of a barrier significantly reduces aerosol spread. Cold surgical instrumentation and microdebrider use pose significantly less aerosolization risk than a high-speed drill. Procedures requiring drill use should carry a special designation as an "aerosol-generating surgery" to convey this unique risk, and this supports the need for protective personal protective equipment.
