BACKGROUND: Adequate personal protective equipment is needed to reduce the rate
of transmission of COVID-19 to health care workers. Otolaryngology groups are
recommending a higher level of personal protective equipment for
aerosol-generating procedures than public health agencies. The objective of the
review was to provide evidence that a.) demonstrates which otolaryngology
procedures are aerosol-generating, and that b.) clarifies whether the higher
level of PPE advocated by otolaryngology groups is justified. MAIN BODY: Health
care workers in China who performed tracheotomy during the SARS-CoV-1 epidemic
had 4.15 times greater odds of contracting the virus than controls who did not
perform tracheotomy (95% CI 2.75-7.54). No other studies provide direct
epidemiological evidence of increased aerosolized transmission of viruses during
otolaryngology procedures. Experimental evidence has shown that electrocautery,
advanced energy devices, open suctioning, and drilling can create aerosolized
biological particles. The viral load of COVID-19 is highest in the upper
aerodigestive tract, increasing the likelihood that aerosols generated during
procedures of the upper aerodigestive tract of infected patients would carry
viral material. Cough and normal breathing create aerosols which may increase the
risk of transmission during outpatient procedures. A significant proportion of
individuals infected with COVID-19 may not have symptoms, raising the likelihood
of transmission of the disease to inadequately protected health care workers from
patients who do not have probable or confirmed infection. Powered air purifying
respirators, if used properly, provide a greater level of filtration than N95
masks and thus may reduce the risk of transmission. CONCLUSION: Direct and
indirect evidence suggests that a large number of otolaryngology-head and neck
surgery procedures are aerosol generating. Otolaryngologists are likely at high
risk of contracting COVID-19 during aerosol generating procedures because they
are likely exposed to high viral loads in patients infected with the virus. Based
on the precautionary principle, even though the evidence is not definitive,
adopting enhanced personal protective equipment protocols is reasonable based on
the evidence. Further research is needed to clarify the risk associated with
performing various procedures during the COVID-19 pandemic, and the degree to
which various personal protective equipment reduces the risk.
