This operation will be discharged in less than half a month, and the main thing after operation is anti-inflammation. No general anesthesia is needed. After all, general anesthesia has certain risks. If you can have local anesthesia, you should not have general anesthesia. It is estimated that doctors will not advocate general anesthesia then. In fact, it is much easier after local anesthesia than general anesthesia, and it is too painful after general anesthesia. As for the cost, it is not very clear. If you want to consult, call the hospital you want to go to and ask them. After the call from the ENT department, a nurse or doctor will explain it to you. Don't worry about the danger of the operation. Good luck with your surgery.
