What is autologous rhinoplasty？Autologous rhinoplasty is to extract some tissue rhinoplasty materials from the subject, and then implant them into the nose after treatment, so as to achieve the purpose of rhinoplasty. The biggest advantage of autologous rhinoplasty compared with traditional rhinoplasty methods, such as prosthetic rhinoplasty, is that the material comes from the subject itself, there is no allergy and rejection, and the rhinoplasty effect is very natural.
Firstly, the amount of tissue needed was confirmed according to the type of autologous augmentation nose, and then the selection site of the material was determined. Thirdly, the autologous augmentation nose takes out the cartilage around the navel, armpit, ear or nasal septum and rib for processing and shaping. Finally, the sculpted tissue was surgically implanted into the nose, corrected and fixed. Autologous rhinoplasty can generally take its own skin flap tissue, from ear cartilage, nasal septal cartilage and costal cartilage.
Common nasal augmentation materials
Autologous rhinoplasty is a way to extract some tissues from other parts of the subject’s body, but not all tissues can be used for rhinoplasty. Autologous rhinoplasty can be divided into three categories according to material categories: autologous dermal tissue rhinoplasty, autologous fat rhinoplasty and autologous cartilage rhinoplasty.
Augmentation rhinoplasty with autologous dermal tissue
Autologous dermal rhinoplasty is a new and most scientific rhinoplasty technique, which is different from the traditional rhinoplasty using allogeneic artificial materials. Autologous dermal augmentation rhinoplasty is to completely take the human body’s own dermal tissue for augmentation rhinoplasty. After survival, it is its own nasal bridge tissue. With people’s metabolism, life and death, it is completely a part of the body, which can ensure the absolute nature of shape and feel. Like natural, it has no hard feeling of prosthesis, and the feel is very natural.
1,Prepare autologous dermis. Dermal tissue is cut from other parts of itself. Common parts include periumbilical and gluteal sulcus. It is generally believed that these two parts are relatively hidden, and dermal tissue has a certain thickness and toughness.
2,Take the flat lying position, cut the skin around the umbilicus, take the subcutaneous true tendon membrane fat composite flap, and the length is consistent with the length of the bridge of the nose
3,Nasal infiltration anesthesia, separation of nasal soft tissue, separation of nasal dorsal soft tissue.
4,Trim the real pimp and implant it into the cavity. Suture the incision. External fixation of nasal clip.
Autologous fat augmentation nose
Autologous fat nose augmentation is a kind of nose augmentation surgery that uses liposuction technology to extract fat from other parts of the body with excess fat, which is implanted into the nose after professional and special treatment such as screening and cleaning, and then molded. However, autologous fat will be absorbed by its own cells, so it should be injected at times and in parts. In this way, the number of fat left will be basically stable after multiple injections, and the nasal augmentation effect will not disappear.
Usually, the effect of autologous fat rhinoplasty can be maintained for 5-8 years. The specific time is determined according to your personal constitution and the speed at which your body consumes fat. Some people may be longer or others will be shorter.
Autologous cartilage augmentation nose
Autologous cartilage rhinoplasty is the most popular kind of autologous rhinoplasty. The cartilage commonly used for rhinoplasty are ear cartilage, nasal septal cartilage and costal cartilage. These three materials have their own advantages and disadvantages.
1,Ear cartilage: take the ear cartilage at the back of the ear fossa to raise the nose. The ear cartilage at the back of the ear fossa will regenerate, and the appearance will not change. Moreover, the wound can be hidden behind the ear and is not easy to be found. The thickness of the ear cartilage is just suitable for placing at the tip of the nose. Ear cartilage transplantation has good histocompatibility and stability. It can heal with the local tissue of the nose. It is easy to fix without displacement and rejection; It is also very convenient to obtain, and it is easy to carve and trim the shape. It is an ideal nose augmentation material.
2,Nasal septal cartilage: nasal septal cartilage is a plate-shaped cartilage that plays a role in dividing the two nasal passages. When it is removed as a whole, it can not only maintain the integrity of the nasal shape, but also obtain the required materials. Moreover, the material part is in the same incision as nasal plastic surgery without additional surgery. It is really the policy of “one arrow and three carving”. For example, the nasal septum extension transplantation can make the nose tip forward and down after being fixed in front of the nasal septum, so as to solve the problems of “facing the nose” and “exposing the nostrils”.
3,Costal cartilage: it mainly solves the difficult rhinoplasty. For some Asians with severe nose “collapse”, the development of nasal septum is very imperfect, but it is also this group of people who need more “parts”. As another representative of hyaline cartilage, costal cartilage has a large number of sources, reliable texture and safe sampling methods. Moreover, it is the “ultimate weapon” for all kinds of difficult congenital nasal malformations and acquired nasal malformations caused by trauma or surgery.
Advantages of autologous cartilage augmentation rhinoplasty
1,Autologous cartilage augmentation nose adopts its own cartilage tissue, which has good histocompatibility and stability without displacement;
2,Autologous cartilage rhinoplasty has less absorption and high survival rate. It can survive even without blood supply;
3,Autologous cartilage augmentation nose will not have rejection reaction, and its safety is guaranteed;
4,The hand feeling after operation is real. There is no need to worry about normal contact with the nose after operation. You can push the nose, and the hand feeling is soft and realistic.
