Lower Airway Conditions Contribute to the Prediction of Polyp Recurrence in Chronic Rhinosinusitis With Nasal Polyps and Comorbid Asthma

Key Points

• The aim is to identify independent risk factors that predict polyp recurrence in patients with chronic rhinosinusitis and asthma.
• Evaluated duration of asthma and specific peak expiratory flow ratios.
• Developed a predictive model incorporating ethmoid sinus scores.
• Analyzed the model's effectiveness in predicting polyp recurrence.
• Duration of asthma and specific peak flow ratios are identified as independent risk factors for polyp recurrence.
• The predictive model using lower airway factors demonstrates good predictive value for polyp recurrence in patients.
