This randomized study compares operative techniques in chronic rhinosinusitis with polyposis (CRSwNP) surgery. It aims to evaluate outcomes in asthma and CRSwNP, safety and costs. The investigators want to see if patients with certain clinical and/or genetic predispositions will benefit from extended surgery. They also aim to find biomarkers for detection and management models for of severe airway inflammation and to further develop markers for progressive disease forms.
