Chronic Rhinosinusitis with Nasal Polyps (CRSwNP)

Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is a long-term inflammatory condition of the nasal passages and sinuses characterized by the growth of soft, painless, noncancerous polyps in the lining of the nose or sinuses. This inflammation can block normal sinus drainage and airflow, leading to symptoms such as persistent nasal congestion, reduced or lost sense of smell, facial pressure, runny nose, and postnasal drip lasting more than 12 weeks.
