Incision of nasal margin or endochondral incision is made in nostril to expose alar cartilage and nasal cartilage, and the cephalad part or caudal part of alar cartilage is removed as appropriate. The cut cartilage, after cutting and shaping, is stitched on the top of the vault to raise the nose, or the external ear cartilage can be cut for transplantation.

2. Bilateral alar cartilaginous foot approach.

Make lateral incision of bilateral nasal columella, expose the medial foot and alar cartilage vault, remove the soft tissue between the two medial feet, and then make mattress suture at the upper and lower ends, that is, close the two medial feet. This method can raise the nose by 2-3 mm.

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