Hello, genetic, only plastic surgery. 1. Cartilage transplantation method: make a nasal margin incision or an endochondral incision in the nostril to expose alar cartilage and nasal cartilage. According to the condition of the nasal tip, the alar cartilage head or the nasal cartilage tail is removed. After cutting and shaping, sew the cut cartilage at the top of the vault to raise the tip of the nose, or cut off the turbinate cartilage for transplantation. 2. Using the method of approaching the medial foot of bilateral alar cartilage, the lateral incision of bilateral nasal columella was made to remove the soft tissue between the two medial feet, and then mattress suture was made at the upper and lower ends, that is, the two medial feet were closed. 3. Wedge-shaped resection of alar base. Wedge-shaped full-thickness tissue is removed at the alar base on both sides, so that the nostrils are adducted and the dome is protruding, that is, the tip of the nose is raised. This method is better for the shape of the tip of the nose, but the tip of the nose is slightly lower.
