Nasal alar reduction, that is, making a nasal margin incision in nostril, or making an incision in alar cartilage to expose alar cartilage and alar lateral cartilage, and cutting off the head or tail of alar cartilage as appropriate. The alar cartilage was removed, shaped and sutured to the top of the nasal vault to raise the alar cartilage. You can also cut the auricle cartilage for transplantation.

Bilateral rhinoplasty and bilateral columella cartilaginous foot closure rhinoplasty is to make an external incision on bilateral columella, expose columella cartilaginous foot and fornix, remove two medial soft tissues, and then make a mattress suture at the upper and lower ends of the proximal end to close two medial cartilaginous feet. This method can raise the nose by 2-3 mm.

If the nose shape is good, but the alar is slightly lower, the wedge-shaped full-thickness tissue is removed on both sides of the alar base, so that the nostrils are adducted and the nasal vault is raised.
