Yesterday a girl who booked an appointment for a double segment rib cartilage rhinoplasty came with a message; my boyfriend is heartbroken for me, we discussed it and he is willing to offer his ribs for me to make my nose! I’m so touched by their true love, but I have to tell you, you can’t accept this love he wants to give you! Cartilage rhinoplasty is very popular among candidates, especially suitable for some beauty loving girls who can’t accept prosthetic rhinoplasty, but some people are afraid of taking autologous cartilage pain, and now there is a rhinoplasty material – allogeneic rib cartilage, which can be used directly, but recently someone asked Xiao Mei what is the difference between allogeneic cartilage and autologous cartilage? How to choose? What is autologous cartilage? There are 3 types of autologous cartilage: ear cartilage, nasal septum and rib cartilage for rhinoplasty. For example, if our nose is hit by external force, cartilage can protect other hard nasal bones from breaking, and the ear will not break even if it is vigorously twisted, so autologous cartilage is very suitable for rhinoplasty material – good texture, elasticity, not easy to rejection and safer. If the ear cartilage is taken, the changes in the ear will not be obvious if the ear cartilage membrane is retained. Rib cartilage is usually taken from the sixth or seventh rib, which can be a little painful in the early postoperative period. Advantages of autologous cartilage rhinoplasty: 1. Abundant amount of cartilage tissue: it can be used to simultaneously require nasal dorsal elevation, nasal tip, nasal column extension, etc., so it is one of the excellent choices for rhinoplasty. 2. High plasticity of cartilage: it not only has a certain hardness, but also is very flexible, so it can be sculpted at will with the ideal shape, length, thickness and curvature, with a natural feel and good effect after surgery. 3. Wide application of cartilage: it can be made into both Cartilage is an active material: it is easily viable, will not be rejection, has low absorption rate, will not penetrate the skin, and has good compatibility with the nose. What is allogeneic cartilage? Allogeneic cartilage is a biological material donated by humans. Donors are required to be under 35 years old and undergo strict disease screening, and must be negative for HIV and hepatitis C antibody serology. The donated bones need to be autoclaved for DNA inactivation, deoxygenated and deacidified, and irradiated before they can be used as a commercial product. However, allogeneic bone (also called homogeneous bone) was initially used for bone defects caused by fractures, later for oral dentistry, and in recent years for plastic surgery. However, allograft cartilage is mostly rib bone, because cartilage from other areas, such as nasal septum cartilage and ear cartilage, has less bone mass and is less supportive. Rib cartilage has been developed for use in allografts because of its high bone volume and strong support. Who is suitable for allograft rib cartilage rhinoplasty: people who, after multiple rhinoplasty procedures, no longer have sufficient autologous cartilage to use; people who do not want to use autologous cartilage; people with severe nasal deformities who need a large and highly supportive material. Advantages of allogeneic rib cartilage rhinoplasty: reduced self-injury and postoperative pain; high hardness and strong support; sufficient sources of material, no intraoperative dilemma; lower deformation rate than autologous cartilage. Comparison of four types of materials: in summary, if you have enough cartilage of your own or it is recommended to choose autologous cartilage rhinoplasty, which can be used in a wider range of areas; however, if the autologous cartilage is not enough or afraid of pain then allograft cartilage is also a good choice, but the surgical price of allograft cartilage will be more expensive, so it is still recommended that you choose according to your own situation.
