Chronic Rhinosinusitis with Nasal Polyps.

A 50-year-old man presents with a 5-year history of progressive nasal obstruction and reduction in his sense of smell. Symptoms were initially intermittent but have become persistent and very bothersome, with the patient rating them as severe. He reports sleep disturbance and postnasal drip and recently received a diagnosis of asthma. Alcohol consumption exacerbates his nasal congestion.
