Nasal polyps are a common and frequently occurring clinical disease, consisting of benign neoplasms in the nasal cavity and paranasal sinuses. Clinically, nasal polyps are primarily treated through surgery, specifically functional endoscopic sinus surgery for the removal of polyps under nasal endoscopy. Nasal polyps have a certain probability of recurrence. After a second recurrence, a second surgery is required. Following surgery, it is necessary to regularly follow up with cleaning of the nasal and sinus cavities, and to actively use certain medications, such as corticosteroids and some macrolide anti-inflammatory drugs. Additionally, during nasal polyp surgery, some tissues should be removed for biopsy to avoid confusion between nasal polyps and papillomas.
