The general comprehensive rhinoplasty always uses prosthesis for nose bridge and autologous cartilage for tip shaping. For nasal tip shaping, the effect of prosthesis and autologous fat filling are not very ideal, only autologous cartilage can be used to achieve good nasal tip shaping. The tip of the nose can be shaped by using ear cartilage, rib cartilage or nasal septum cartilage. Ear cartilage is basically only used for tip sculpture or small-scale supplementation because the amount of bone taken is minimal; septal cartilage takes a slightly larger amount of bone and can be used for the tip of the nose, the nasal column or the dorsum of the nose which does not require much bone filling, etc. So for nasal tip shaping, which cartilage is good to choose? 1. Ear cartilage Ear cartilage is soft and has a natural curvature, making it ideal for use as a “cover graft”, just like a roof tile. By placing the trimmed and rounded ear cartilage on the tip of the nose, it can make the tip of the nose look more curved, rounded and natural, as if it were made in heaven. Its histocompatibility is good and stable. It is easy to be fixed and will not be displaced; no rejection; less absorption, low absorption rate of autologous cartilage, can survive without blood supply; simple operation, taken from the body, easy to obtain. It is easy to sculpt and trim the model, and is the ideal material for rhinoplasty. Usual nasal prosthesis materials, the shape is more fixed L-shaped, and can not make a beautiful nasal tip, while the use of ear cartilage can completely achieve the effect of shaping the tip of the nose. It eliminates the deformation and perforation of the nose. Realistic touch, autologous cartilage rhinoplasty does not have to worry about normal contact with the nose after the operation, you can push and press the nose, and it feels soft and realistic. The ear cartilage in the ear fossa will be regenerated and the appearance will not be changed, and the wound can be hidden behind the ear so that it is not easy to be found. 2. Rib cartilage has a low absorption rate; does not penetrate the skin; does not have blood vessels; is easily viable; does not cause rejection; can be sculpted to the ideal shape at will; and is widely used. This surgical method was first reported in the United States in 2004 and has been proven in a large number of clinical cases to be the safest, most effective and long-lasting method available. Since the tissue is autologous, there is no allogeneic rejection; the shape of the nose is more natural and realistic. The amount of autologous rib cartilage tissue is especially suitable for rhinoplasty repair and complex rhinoplasty patients. 3.Nasal septum cartilage The physiological characteristics of nasal septum cartilage and ear cartilage are different. Nasal septal cartilage is transparent cartilage with hard texture and flat shape, which is suitable for use as a support graft, just like the pillar material used for building houses. With the support of the septum, the tip of the nose can be easily raised to the right height, giving you a “chiseled” tip. It can also effectively lengthen the nose and solve the problem of “skyward nose” and “leaky nostrils” perfectly. As autologous septum cartilage is part of autologous tissue transplantation, it avoids allogeneic tissue rejection and has high safety. In the same autologous cartilage rhinoplasty incision, the septum cartilage extraction surgery and nasal columella lengthening surgery are performed without the need to make a second autologous cartilage rhinoplasty area in other parts of the body, and the total human incision area is reduced. The septal cartilage is easy to shape and fix, and the support effect is obvious, so it is easier to achieve the cosmetic rhinoplasty requirements for customers with indications. The hard texture of the septum cartilage makes it easy to shape a rounded and curved nose, and it can even be used to treat nasal septal curvature or to correct nasal congestion and other disease problems in passing.
