Nose reduction surgery is to make an incision along the lateral side of the nostril cartilage, remove fat and connective tissue according to the condition of the nose, and sew the incision after trimming to make the nose more delicate. The incision is located at the base of nostril and the lower part of nostril groove. Under local anesthesia, part of the full-thickness tissue of the nostril base was properly removed, and then the nostril was rotated inward to narrow and sutured intermittently in layers.
