Nasal polyps are curable, and patients can be cured through localized surgical treatment. The cause of nasal polyps is unknown, generally due to chronic inflammatory stimulation, leading to bilateral nasal turbinate mucosal diffuse congestion, edema, proliferation, and prolapse, resulting in nasal polyps. They are also often secondary to allergic rhinitis. Nasal polyps generally occur bilaterally, causing the patient to have persistent nasal congestion that progressively worsens. In addition, patients may experience facial swelling, headache, and yellow nasal discharge, among other symptoms. During an examination with an electronic nasoscope, pale lychee-like masses can be observed in the nasal passages on both sides. These are soft, painless, and not prone to bleeding. In terms of treatment, nasal polyps require endoscopic nasal polyp removal surgery and sinus opening surgery for a cure.
