The literature search yielded 3406 returns. The PRISMA flow chart can be
found in Figure 1 . With duplicates removed, 3305 were screened
based on both titles and abstracts. In keeping with the above criteria,
3275 articles were excluded based on lack of relevance. Twenty-nine
full-text articles were scrutinised for eligibility. Six were excluded:
two review articles6,7 and four editorial/opinion
pieces.8-11 One further study was identified from
analysis of reference lists,12 resulting in a total of
24 articles meeting eligibility criteria.
Given the heterogeneity of the studies (Table 1 ), results were
stratified into two broad themes: 1. aerosolisation of droplets during
endonasal surgery, further subdivided into those which consider
macroscopically visible droplets (1.1) and those which consider smaller
particles (1.2), and 2. mitigation of risk.
