First of all, it is clear that no doctor can guarantee the complete eradication of nasal polyps. It can only be said that surgical treatment is the best way, and careful nursing according to doctor's advice after operation can minimize the recurrence rate. First, there is a polyp in the nose, which is medically called nasal polyps. Nasal polyps are caused by swelling of nasal mucosa and loss of normal function. After a cold, nasal congestion is the result of swelling of nasal mucosa. When oral drugs or local nasal drops are used, the swelling of the mucosa in the cavity will subside and the nose will be ventilated again. However, if the mucosa in the nasal cavity is swollen repeatedly, it will lose its elasticity for a long time like a balloon filled with water, and it will not recover, forming nasal polyps. Second, once nasal polyps are found, they should be treated surgically. Pathological examination must be done for the "nasal polyp"-like tissue removed by surgery to rule out the possibility of malignant transformation. Especially for patients with unilateral nasal cavity tumor, doctors often take some tumor slices for detection before operation. Because there may be nasal tumor complicated with nasal polyps, or deep tissue malignant transformation of nasal polyps, or deep lesions, only the surface of pathological tissues is covered with nasal edema mucosa, and the results of preoperative biopsy are for reference only, and the final treatment plan is subject to the final pathological conclusion of surgery. Because the nasal cavity is adjacent to the eyes and brain, the operation is dangerous, especially the bone plate, which is only very thin from the eyes, is called paper template, and it is easy to be damaged due to careless operation during the operation. It is not uncommon to report blindness after nasal polyp surgery. Nasal polyp surgery requires anesthesia. General anesthesia or local anesthesia can be selected according to hospital conditions. Generally, when performing surgery under local anesthesia, the patient is awake, and nervousness will aggravate the pain. Therefore, we must cooperate with the doctor during the operation, so as not to affect the doctor's judgment, because when the operation scope is close to the orbit and skull base, the patient will have severe pain, and the surgeon will be more careful at this time. General anesthesia is a painless operation with the help of an anesthesiologist. Conditional hospitals can control blood pressure under general anesthesia at the same time, with less intraoperative bleeding, clear surgical field and fewer complications. If under general anesthesia, a certain proportion of local anesthetics and vasoconstrictors are used for cotton surface anesthesia of nasal cavity, the effect will be better. At present, nasal polyp surgery is performed in the nasal cavity, and there is no incision on the surface skin. With the popularization of endoscopic sinus surgery, it has become a routine operation. Under good surgical conditions, experienced doctors can complete it in an hour and a half, or even half an hour. Because of painless, short operation time and less bleeding during operation, the patient recovered quickly after operation. During the operation, doctors usually put the diseased tissues taken from the nasal cavity and paranasal sinuses into a bowl filled with normal saline. If the cut tissue is found floating in the bowl, it is often fatty tissue, which indicates that the orbital cardboard is damaged, and purple shadows will appear around the orbit after the operation, which is called' panda eye' clinically. With the development of medicine and the application of CT, doctors can make clear the relationship between nasal polyps and eyes and skull base before operation, and the safety of operation is greatly improved. Patients with postoperative nasal polyps should go to the hospital regularly in strict accordance with the doctor's requirements. Doctors find small mucosal edema, which will be removed in time to avoid major surgery again. No doctor can guarantee that nasal polyps will not recur after operation, but through careful nursing after operation, the recurrence rate can be minimized. In addition, postoperative patients should take medicine in time after catching a cold to prevent nasal polyps from recurring due to local stimulation of pus produced by sinusitis. Third, preventing the occurrence of nasal polyps is fundamental to avoid the pain of nasal polyps. First of all, reduce colds and avoid repeated edema of nasal mucosa. The disease closely related to nasal polyps is allergic rhinitis. Such patients often have itchy nose, sneezing, runny nose and other symptoms when they smell a certain smell or encounter changes in hot and cold air in a certain season every year. In hospitals, doctors often meet patients with nasal polyps, asthma and allergic to aspirin, which is called aspirin triad.
