Nasal polyps must first undergo a biopsy before surgical treatment can proceed. A clear diagnosis is necessary. If it is a nasal polyp, local surgical removal is needed. If it is a bleeding or malignant nasal polyp, local hemostasis, radiotherapy, or chemotherapy is required. Nasal polyps can occur for various reasons clinically, and are generally directly related to chronic rhinitis or chronic allergic rhinitis in patients. They are polyps formed from the diffuse congestion, edema, and prolapse of the nasal concha mucosa due to long-term inflammatory stimulation. Nasal polyps can lead to persistent nasal congestion in both nasal cavities, along with a sense of swelling and foreign body sensation in the nasal cavity. In severe cases, it can cause a decrease in the sense of smell and memory. It is necessary to go to the hospital for a detailed examination. An electronic nasal endoscope and sinus CT can determine if there are any abnormal tumors. If a tumor is found, a local biopsy will be required. If it is confirmed as a nasal polyp, local surgical removal is necessary for treatment.
