Nasal polyps are currently primarily treated by two methods: medication and surgery. If there are many polyps, surgery is usually considered necessary. There are two types of anesthesia used in surgery: local anesthesia and general anesthesia. Generally speaking, general anesthesia, administered through endotracheal intubation or a laryngeal mask, is relatively safe and does not significantly affect the surgery or the patient themselves. However, there are certain risks involved, such as anesthesia accidents or slow metabolism of anesthetic drugs, which could trigger other or existing underlying diseases, further increasing the risk. Additionally, there could be damage to the nasal cavity or structures around the nose, such as periorbital ecchymosis, nasal bleeding, severe bleeding leading to shock, and some might experience changes in vision or visual field, or effects on the olfactory nerves.
