Due to structural anomalies in the nasal airway, the Intranasal Cortico-Steroid Sprays(INCS) may not be reaching their intended areas in the sinuses.
Next Steps
Please get a coronal plain CT scan of the nose and paranasal sinuses to help your ENT Surgeon better understand why you are not responding to the INCS and do corrective Endoscopic Nasal Surgery to remedy the same.
