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

Stereotactic Radiosurgery for Skull Base Meningiomas

Complete resection of meningiomas occurring at the skull base may be difficult, due to the proximity of critical neurovascular structures. Due to the benign nature of these lesions, most patients with skull base meningiomas have an extended life expectancy. The goal of treatment for these lesions, therefore, revolves around long-term tumor control without worsening neurological function. Stereotactic radiosurgery is one of three main treatment options for the treatment of cranial base meningiomas, and has been shown to have similar rates of tumor control with safe administration within 3–5 mm of cranial nerves and brainstem. In this chapter, we review the literature reporting outcomes following use of stereotactic radiosurgery for these lesions, and the rationale for decision-making about treatment for these lesions
