EPOS2020 will be the latest in the EPOS series of guidelines on rhinosinusitis from an international cohort of experts in the field and will build on the success of the previous EPOS papers.

Now once more we invite leaders in the field to critically appraise the latest literature and provide a comprehensive review of the key topics. Our goal is to produce EPOS2020 in an accessible format with clear research priorities, which will inspire researchers to study the epidemiology and management of ARS and CRS, use standard definitions of the disease, implement genotyping, reduce unnecessary (antibiotic) treatment and form new collaborations to answer unmet research questions.
