Nasal alar plastic surgery is divided into general anesthesia and local anesthesia, mainly depending on the scope of nasal alar plastic surgery. If general anesthesia is used, the patient will be in a deep sleep state without any pain during the whole alar plastic surgery. If local anesthesia is selected, patients with alar plastic surgery will stay awake during alar plastic surgery, but the nose and surrounding facial tissues will feel numb and have a little pain.
