International Consensus Statement on Rhinology and Allergy: Rhinosinusitis

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

Survival outcomes for stage-matched endoscopic and open resection of olfactory neuroblastoma

Background: Advanced-stage olfactory neuroblastoma requires multimodal therapy for optimal outcomes. Debate exists over endoscopic endonasal surgery in this situation. Stage-matched open and endoscopic surgical therapy were compared. Methods: Patients from 6 cancer institutions were assessed. Stratification included dural involvement, Kadish stage, nodal disease, Hyams' grade, approach, and margin status. At follow-up, local control, nodal status, and evidence of distant metastases were recorded with any subsequent therapy. Statistical analyses to identify risk factors for developing recurrence and survival differences were performed. Results: One hundred nine patients were assessed (age 49.2 ± 13.0 years; 46% women) representing Kadish A stage (10%), Kadish B stage (25%), and Kadish C stage (65%). The majority of the patients (61.5%) underwent endoscopic resection, 53.5% within Kadish C stage. Within-stage survival analysis favored endoscopic subgroup for Kadish C stage (log-rank P =.017) nonsignificant for Kadish B stage (log-rank P =.39). Conclusion: Stage-matched survival was better for the endoscopically treated group compared to the open surgery group, with high negative margin resections obtained
