As the saying goes, "a flower on the face, all depends on the nose." the nose is in the middle of our facial features, which determines the coordination, beauty and temperament of the facial features. But when you first want to do rhinoplasty, you will be confused, and you will have some hesitation in the choice of filling materials. I don't know which material is the best for me? Today, Xiaobian will give you a strategy as an aid! First of all, we need to know what kinds of materials are used for nose augmentation?
What are the filling materials for augmentation rhinoplasty?
1. The duration of maintenance effect of hyaluronic acid augmentation rhinoplasty is different according to different injection price. The general price of hyaluronic acid augmentation rhinoplasty is about 2-3000, which can be maintained for about 6-10 months or even shorter after operation. The imported hyaluronic acid whose price is about 10000 will be maintained for a long time, but it will not be permanent. The characteristics of hyaluronic acid nasal augmentation are small trauma, fast recovery, and it is more suitable for patients who are afraid of surgery and pain. But hyaluronic acid augmentation can only be done by simply raising the bridge of the nose. At present, there are totally 4 kinds of hyaluronic acid imported from 15 domestic legal brands. There are 11 kinds of domestic products: run Baiyan, Haiwei, Shuyan, EME (Yimei), bonida, iflay, fasili, singfiller, formaderm (Taiwan's name is "Fu Liang"), deman and Bofei. Four kinds of imports: Ruilan No. 2, Yiwan, aliwei and joyarden
2. Silicone prosthesis
Silica gel is the most commonly used material in augmentation rhinoplasty at present, and L-type prosthesis and willow leaf type are mostly used, in which L-type is divided into one-stage, two-stage and three-stage shapes.
Advantages: the price of silicone prosthesis is is relatively cheap, generally between 30-10000 yuan
The operation time of simple prosthesis augmentation is about 30 minutes to 1 hour. It has been many years since silicone prosthesis was born, so the technology has been very mature in clinical practice, and the postoperative maintenance time is long.
Disadvantages: silica gel prosthesis can't grow together with nasal tissue after operation, because of its weight and gravity, it is easy to fall down after implantation, which will compress the skin of the nose, and may cause the skin of the nose tip to become thin or even prick the skin after operation.
Therefore, it is recommended to use silica gel prosthesis with its own cartilage for surgery.
3. Self organizing materials
The autogenous tissue is usually ear cartilage, costal cartilage and septal cartilage, and the "material" of human body itself. It has a good hand feeling and realistic effect after operation.
(1) ear cartilage: the ear cartilage at the back of the ear socket is taken to augment the nose. The cartilage in this area is behind the ear, so the wound is hidden and hard to find. But because of the thickness of ear cartilage, it can only be used at the tip of nose.
(2) nasal septal cartilage: nasal septal cartilage is a plate-shaped cartilage that plays a role in dividing the two nasal passages. It keeps a part in front and above, and takes out the whole part in the back and below. It does not affect the integrity of the nasal morphology after operation, but also can get the required materials.
(3) costal cartilage: take it from the sixth or seventh rib of the human sternum. This place is closest to our skin. As long as we cut a very small wound, we can take out enough amount, generally about 4cm. Costal cartilage is mainly aimed at the difficult rhinoplasty, because it is the natural material of human body, so there is no need to worry about the difference after operation, costal cartilage is well shaped, and the shape is lifelike after operation. The costal cartilage price is relatively high, about 40000-60000.
4. Expanded prosthesis
Puff is a kind of nontoxic polymer, which is widely used in medical products. It has certain elasticity. In clinical medicine, artificial blood vessels and artificial heart capsule are all made of puff materials.
Advantages: light material, good hand feel, close to human nasal tissue, natural effect after operation, expanded body has special microporous structure, during the recovery period, the nasal tissue can be combined with microporous so as to make the prosthesis more stable in the nasal cavity, expanded body material is light, so there is no need to worry about the problem of dropping and piercing the tip of the nose after operation, and the cost of expanded body is generally about 80-20000.
Disadvantages: because of the microporous structure of the puff, it is easy to hide the bacteria. Because of the special structure of the puff, it can not be exposed to the air for a long time, which is a test of the doctor's technology, otherwise it is easy to infect. So it's important to choose regular hospitals and doctors.
What is the difference between silicone augmentation nose and expanded augmentation nose?
◆ tissue compatibility
Puff and silica gel are commonly used nasal plastic materials. They have high and low temperature resistance, chemical stability, corrosion resistance and tissue compatibility. They are non-toxic, non carcinogenic and non teratogenic. The puff material has a special structure. The blood vessels and nerves in the nasal cavity can grow into the puff, so that the puff and its own tissues can be fused together. Silica gel prosthesis can not grow together with human tissues and be implanted After the body, may present the slight inflammation reaction, the later period around will form the nasal cavity envelope. Plasticity
The plasticity of the two prostheses was compared. The elasticity and stereoscopic sense of the expanded material are relatively poor, so it is not suitable to carve and shape; the silicone prosthesis itself has the basic shape of the nose, and can be engraved on the basis of it. The silicone prosthesis can be prefabricated into various shapes and models with nose tip, nose wing, nose columella, etc., with good flexibility and elasticity, and strong stereoscopic sense.
Stability
Through clinical observation, the swelling material will lose its original flexibility and become very hard when the tissue is growing in, which makes the hand feel lose the sense of reality and appears unnatural after the nose operation; the silicone prosthesis does not have such a problem, and the silicone prosthesis will not change the shape or feel over time. The postoperative effect was stable and natural.
I'm sure that after you read this popular science article, you already have some understanding of nose augmentation materials. If you want to have a delicate and small beautiful nose, you can choose time plastic surgery. We have a more professional plastic team to make you safe and beautiful.
