Suggestion: We must pay attention to this question. The answer to your question is as follows: In the case that the alar is not too wide, we can insert an auxiliary column into the columella of the nose, and the tip of the nose is erected by cartilage transplantation, so that the alar amplitude is reduced and no other operation is needed. Nasal alar resection is mainly suitable for people or blacks, and it is a method to reduce the alar when the nasal base is too wide or the nostrils are too large. The main clinical methods to reduce the alar are: 1. If the alar is wide and the nostril is wide, partial resection of the alar base and nostril reduction can be carefully performed. The designed incision is located at the base of alar and the lower part of alar sulcus. Under local anesthesia, part of the full-thickness tissue of the alar base was properly removed, then the nostril was narrowed and sutured intermittently in layers. The length of scar visible after operation is generally less than 1CM. 2. If the alar margin is wide, the alar free margin can be partially cut off, and the incision can be stitched on the inner surface of the alar after trimming, thus improving the phenomenon that the alar is too large.
