Abstract
Aerosol generation during temporal bone surgery caries the risk of viral transmission. Steps to mitigate this problem are of particular importance during the coronavirus disease 2019 pandemic. To quantify the effect of barrier draping on particulate material dispersion during temporal bone surgery. The study involved a cadaveric model in a simulated operating theatre environment. Particle density and particle count for particles sized 1-10 μ were measured in a simulated operating theatre environment while drilling on a cadaveric temporal bone. The effect of barrier draping to decrease dispersion was recorded and analysed. Barrier draping decreased counts of particles smaller than 5 μ by a factor of 80 in the operating theatre environment. Both particle density and particle count showed a statistically significant reduction with barrier draping (p = 0.027). Simple barrier drapes were effective in decreasing particle density and particle count in the operating theatre model and can prevent infection in operating theatre personnel.
Highlights
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) caused the outbreak of coronavirus disease 2019 (Covid-19) that started in Wuhan, China, in December 2019
The virus spreads via aerosols, and the nasal and nasopharyngeal regions are associated with high viral loads, thereby putting healthcare professionals, otolaryngologists, at risk of contracting the infection.[2]
Otorhinolaryngologists have a higher risk of contracting the virus as they perform procedures in nasal, oral and oropharyngeal regions, which are areas identified as having a high viral load
