Nasal polyps are a common disease in otolaryngology. The occurrence of nasal polyps is due to chronic inflammation of the nasal cavity and stimulation by physical and chemical factors, leading to proliferative lesions of the nasal mucosa and the formation of nasal polyps. The most effective treatment for patients with nasal polyps is functional endoscopic sinus surgery. After surgery, it is important to change dressings in a timely manner and perform regular follow-ups to prevent recurrence of the nasal polyps. Patients with recurrent nasal polyps usually exhibit significant symptoms such as nasal congestion, purulent nasal discharge, headaches, and nasal obstruction. Recurrence can be confirmed through follow-up examinations such as a CT scan of the paranasal sinuses or electronic frontier inspection.
