The materials used in<p> cartilage rhinoplasty are auricular cartilage, nasal septum cartilage and costal cartilage. & lt/p & gt； & ltp> 1, auricular cartilage is often used to pad the tip of the nose, because the shape of auricular cartilage is similar to that of the nose, thin and elastic, and the tip of the nose molded with it feels softer and more natural, so it can push the nose. & lt/p & gt； & ltp> Of course, auricular cartilage can also be used to lengthen nasal columella, but it is only suitable for short nasal columella, and it will not work if it is too short. & lt/p & gt； & ltp style = \ " text-align:center \ " & gt； & ltimg src = \ "/uploadfile/image/20200318/1584 5041299632.jpg \" alt = \ "Comparison before and after nasal contracture repair \" Height: 282px \ "/>; & lt/p & gt； & ltp>2. The cartilage of nasal septum is hard and smooth, which is the best choice for supporting nasal columella. It is often used to lengthen the columella, raise the tip of the nose or lengthen the nasal septum, and can also correct the nose shape and the height of the bridge of the nose at the same time. & lt/p & gt； In<p> surgery, as long as the nasal septum is extended and fixed in front of the nasal septum, the tip of the nose can move back and forth, which solves the problems of "nose facing the sky" and "nose exposed". & lt/p & gt； & LTP> & ltimg src = \ "/uploadfile/image/20200318/1584 504161335876.jpg \" alt = \ "costal cartilage augmentation.
