With the introduction of the concept of comprehensive rhinoplasty, another misconception is that only cartilage rhinoplasty is comprehensive rhinoplasty, and some even derive that you must take ear cartilage to call it comprehensive rhinoplasty. So what are the types of cartilage and what can they do? Cartilage clinically commonly used for autologous cartilage, allogeneic cartilage, xenogeneic cartilage, the latter two refers to the cartilage removed from the bodies of other people and animals after rejection treatment retained cartilage, the advantage is no human damage but the disadvantage is the same as the prosthesis, not its own material, there is rejection absorption and psychological rejection problems, so do not do to promote. Autologous cartilage materials can be broadly divided into rib cartilage, nasal septum cartilage and ear cartilage. The ear is a typical skin-encapsulated cartilage tissue, which is easily accessible to people. Its advantages are simple to take, little damage to the shape of the tissue structure, and great elasticity; the disadvantages are also obvious: histologically, ear cartilage is elastic cartilage, as the name implies, but the support and shaping force is insufficient, and the tissue will degenerate and fragment and lose support after long-term ischemia. The nasal septum cartilage, which is the cartilage plate in the middle of our nostrils, has the role of support itself, is thicker than the ear cartilage, and is transparent cartilage, as the name implies, its tissue support is greater but its elasticity is slightly limited, so it has an inherent advantage for the support and shaping of the nasal end, which can be done with the same incision as rhinoplasty; its disadvantage is that its own tissue material is limited, and the septum cartilage itself has a supporting role for the nasal cavity and airway. and airway have a supportive role, can not be completely destroyed must retain enough scaffolding, can only take the core area, so the amount of material is even more inadequate; in addition, in the long term due to ischemia after easy denaturation support decreased. The rib cartilage is the most anterior cartilage part of our rib cage, which is transparent cartilage that supports the thorax and rib arch and is mildly elastic. Rib cartilage has a large in vivo storage capacity, and the material is thick, hard and dense, which makes it suitable for use as a dorsal nasal filling and scaffold support. As can be seen, various materials have their own advantages, overall comparison, rib cartilage is the most suitable material for comprehensive rhinoplasty, and can be used alone and meet all the needs of rhinoplasty, and the use of fine sutures, the thoracic incision control in about 50px, and does not affect the aesthetic.
