Rhinoplasty is one of the most difficult surgeries among all kinds of plastic surgeries. Due to the low nasal dorsum characteristic of oriental races, rhinoplasty has become the most commonly performed rhinoplasty surgery. However, the traditional rhinoplasty in most Asian countries is almost always to place a prosthesis directly into the dorsum of the nose, without involving the change of the overall bone and cartilage structure of the nose, until the last 20 years, autologous cartilage rhinoplasty technology has gradually become popular in Asian countries ……. So what is autologous cartilage rhinoplasty? What are the advantages and disadvantages of ear cartilage, rib cartilage and septum cartilage rhinoplasty? As the New Year is approaching, let me secretly tell the beauty seekers the secrets of the celebrity “nose” you look good …… Cartilage form distinction First of all, no matter whether it is ear cartilage, rib cartilage or septal cartilage, they are the most common cartilage taken by rhinoplasty, in which the ear cartilage belongs to the elastic cartilage, the cartilage is thinner, the elastic fiber is more, it is easy to bend and turn, the strength and rigidity of the smaller; rib cartilage and septal cartilage belong to the transparent cartilage, the tougher is not easy to bend, to be able to provide a strong support strength, especially the rib cartilage. Ear Cartilage Ear cartilage is the easiest to remove. If the auricle is large, a larger piece of cartilage can be obtained with minimal damage and quick recovery. The scarring is hidden and minimal, with little effect on the shape of the auricle, making it the most popular choice for candidates. Utilizing the auricular cartilage mainly for the support of the center of the nasal columella, nasal columella lengthening, nasal dorsum lengthening, and nasal tip shield support, combined with silicone or expandable fabrication materials and cartilage composite, can solve many well-grounded rhinoplasty problems. Rib cartilage Removal of rib cartilage usually requires general anesthesia and hospitalization, while some people use local anesthesia to remove rib cartilage. The 5th to 8th rib cartilage is usually chosen. Some people also prefer to cut the floating rib, which has a longer recovery time and relatively the most visible scarring. Some doctors choose to make the incision in the inframammary fold, which can be relatively hidden. Some surgeons use a 1cm incision to obtain 3-5cm of cartilage in order to minimize scarring. If the skin is pulled hard just to reduce the incision, not only will the scar be heavier after pulling the skin, but it is also not easy to stop bleeding in deep operation, which may cause hemorrhage or tear too much soft tissue, or even tear the pleura to produce a pneumothorax, which is life-threatening. Therefore, we do not recommend taking too much risk just to reduce the incision a little bit, after all, the safety of the surgery is always the first priority. The rib cartilage has sufficient tissue volume to provide the strongest support, and the result is very certain, no matter whether it is for dorsal or columella lengthening. If the candidate is psychologically repulsed by the prosthesis, a full rib rhinoplasty can be done. Of course, this requires the cutting of a larger piece of cartilage. Nasal septum In Europe and the United States most of the septum will be cut. Because their noses are already wide and high, the septum is well developed and has enough tissue. It is very convenient to remove the septum while going through the nasal columella approach, and it can be used as a columella splint graft and a nasal tip shield graft. However, for many Chinese, the nasal dorsum is collapsed and the nasal septum is already poorly developed with very little tissue volume, so it is not possible to cut an adequate amount, and it is often necessary to use it in combination with auricular cartilage. In addition, many people’s nasal septum is too thin and brittle and does not support them well. If the skin of the nose is very hypertrophic, with well-developed sebaceous glands and exceptional toughness, the septum is even more unusable. Moreover, it is not uncommon to have complications such as mucosal tears, hematomas, and septal perforation when the septum is cut. Therefore, rib cartilage grafting may be more suitable for Chinese people.
