The operation definitely needs anesthesia. General anesthesia or local anesthesia can be selected according to the patient's own requirements. For patients who do not need to remove costal cartilage from the body, general local anesthesia is enough. In local anesthesia, the anesthetic is usually injected next to your nose, then the tip of your nose and the back of your nose. General anesthesia is through your vein. In any case, you will have the operation without pain.
