The Mixed Neutrophilic–Eosinophilic Endotype of CRSwNP Blunts Postsurgical Improvement as Determined by the Completeness of Surgery Index

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The Completeness of Surgery Index (CoSI) is a novel metric for assessing surgical quality in chronic rhinosinusitis with nasal polyps (CRSwNP). Structured histopathology (SHP) is helpful for characterizing drivers of inflammation. Integrating these two tools to identify patients at higher risk for surgically recalcitrant disease has
