Nasal polyps are not something everyone has. The main causes of nasal polyps are related to the patient's smoking, drinking, and long-term exposure to physical and chemical factors in the air, which lead to the proliferation of redundant tissue on the surface of the nasal mucosa, blocking the patient's middle nasal passage and nasal vestibule, thereby causing symptoms such as nasal congestion, runny nose, and headaches. When patients with nasal polyps experience nasal congestion and runny nose, our first approach should be anti-inflammatory and symptomatic treatment. Next, it is necessary to perform a thorough diagnosis with an electronic nasopharyngoscope and paranasal sinus CT scan. After a confirmed diagnosis, patients with nasal polyps usually need functional endoscopic sinus surgery, which involves removing the polyp tissue blocking the nasal cavity and opening the sinus openings to restore the normal physiological environment and drainage of the nasal cavity.
