The main symptom is that with the increase of polyp volume or quantity, the situation of nasal congestion will gradually increase. Speaking with nasal sounds, head swelling and discomfort, mostly nasal purulent. Because polyp hyperplasia blocks the nasal cavity, some large ones even expose the nostrils, and even enlarge the nasal cavity and widen the back of the nose, forming an outward bulge, which is called "frog nose" in medicine. If the nose often bleeds and the patient is old, a few patients' nasal polyps will become cancerous, so be vigilant. At present, the only way is surgical resection. For patients with serious systemic diseases, the operation should be cautious or postponed. Jinan Renpin Hospital imported German endoscopes.
