I. Executive Summary Background The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR‐RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR‐RS‐2021 as well as updates to the original 140 topics. This executive summary consolidates the evidence‐based findings of the document. Methods ICAR‐RS presents over 180 topics in the forms of evidence‐based reviews with recommendations (EBRRs), evidence‐based reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. Results ICAR‐RS‐2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence‐based management algorithm is provided. Conclusion This ICAR‐RS‐2021 executive summary provides a compilation of the evidence‐based recommendations for medical and surgical treatment of the most common forms of RS.

Background Oral steroids are commonly used in the management of chronic rhinosinusitis (CRS) with and without nasal polyps (CRSwNP and CRSsNP, respectively). Past reports have included evaluation of the evidence for the use of oral steroids in CRS subtypes. However, a review with evidence‐based recommendations for all CRS subtypes has never been performed. The purpose of this article is to provide a comprehensive, evidence‐based approach for the utilization of oral steroids in the management of CRS. A systematic review of the literature was performed following recommendations of the Clinical Practice Guideline Manual, Conference on Guideline Standardization, and Appraisal of Guidelines and Research Evaluation. Inclusion criteria were: adult population ≥18 years old; CRS; oral steroids as the treatment group; and clearly defined primary clinical end‐point. This review identified and evaluated the literature on the use of oral steroids for CRSwNP, CRSsNP, allergic fungal sinusitis (AFS), and the use of oral steroids in the perioperative period in these patients. Recommendations based on evidence, benefit/harm assessment, and value judgments are made. Oral steroids are strongly recommended for short‐term management of CRSwNP. Oral steroids are also recommended for management of AFS. Oral steroid use in CRSsNP is optional due to insufficient strong evidence. Oral steroids are also strongly recommended in the perioperative period for CRSwNP and AFS. There is no recommendation for oral steroids use in the perioperative period in patients with CRSsNP. The risks of oral steroids are rare, but significant adverse effects must be considered. © 2012 ARS–AAOA, LLC.
