With the continuous progress of the plastic surgery industry, doctors have gradually discovered that in fact, the good things in implant materials should also come from their own tissues, especially as the plastic material for the tip of the nose. This is because in the process of human evolution, the bridge of the nose is a relatively fixed and immobile part, while the tip of the nose is a highly mobile part. If a foreign body is used to support the nose tip, friction will continue to occur between the frequently moving nose tip tissue and the foreign body. Over time, complications of one kind or another will inevitably occur, leading to the failure of the rhinoplasty surgery. Therefore, the internal support of the nose tip uses autologous cartilage, which can not only provide good support but also ensure safety. Autologous cartilage currently mainly includes three cartilage materials: ear cartilage, nasal septal cartilage and costal cartilage.
