If nasal polyps deteriorate, it might lead to associated clinical symptoms, commonly including nasal congestion, runny nose, bloody nasal discharge, headaches, dizziness, and a reduced sense of smell. A small portion of patients may also experience malignant transformation. The specific clinical symptoms vary from individual to individual. After the onset of the condition, it is necessary to promptly visit an otolaryngology department. Undergoing a sinus CT and endoscopic examination can help assess the severity and extent of the condition. Regarding treatment, some patients may consider conservative medication treatment, but others with more severe conditions where the medication is ineffective might need to consider surgical treatment.
