Nasal polyps are a relatively common otolaryngology disease with various clinical symptoms and certain individual differences. If the nasal polyps are few, there might not be obvious clinical manifestations. They could be discovered during physical examinations or nasal endoscopy. If there are many nasal polyps, it could lead to reduced sense of smell, headaches, dizziness, nasal congestion, and runny nose. Overall, different patients exhibit different symptoms. In terms of treatment, it is first necessary to assess the specific severity of the condition, which can be evaluated comprehensively using nasopharyngoscopy and sinus CT scans. Most patients can consider medical conservative treatment, while a small number of patients with numerous polyps might need to consider surgical treatment. (The use of medications should be guided by a professional doctor.)
