Rhinoplasty is a very common plastic surgery at present. Common rhinoplasty materials include silica gel, expander, autologous cartilage and hyaluronic acid used for rhinoplasty. Maybe you've heard of a kind of bone powder rhinoplasty, so is it good? Is it harmful to human body? Bone powder rhinoplasty is a kind of injection rhinoplasty, which generally refers to rhinoplasty with hydroxyapatite artificial bone material, but this method has been eliminated. After rhinoplasty, bone powder is easily broken by external force, so it is difficult to take it out, and the injection method is not easy to form, which is hard and unnatural, and has been banned by the state. With many years of medical experience, I have seen too many cases of operation failure due to improper operation or the use of irregular materials. Some patients who come to me for rhinoplasty have bone powder rhinoplasty in irregular medical institutions, which leads to serious complications such as persistent swelling and skin ulceration. Therefore, in view of the harm of bone powder rhinoplasty to human body, patients must be careful to avoid using this method. The harmfulness of augmentation rhinoplasty with bone meal is 1, which may cause serious complications, such as uneven injection to form nodules under the skin, shallow injection site to cause skin discoloration, and nasal skin may be red, swollen and ulcerated. 2, the shaping effect is not good, especially the tip of the nose. The injected bone powder can only crystallize and harden after 7 days of augmentation rhinoplasty with artificial bone powder. During this period, it is absolutely not allowed to collide with the nose, otherwise the shape of the nose will be deformed. Therefore, the nose bridge deviation after artificial bone powder augmentation is a common complication. And because there is no supporting effect, it has poor effect on people with low nasal tip. 3. The material may deviate, that is, the position changes, which affects the appearance. Moreover, because bone powder is brittle after crystallization, it is easy to break under the action of external force. 4, it is difficult to take out, because the bone powder rhinoplasty material is liquid, it will penetrate into the tissue gap, and it is very difficult to take out. Moreover, it is easy to destroy the normal physiological structure of nasal dorsal tissue when it is taken out, which increases the difficulty of reoperation. In order to reduce the incidence of postoperative rejection, a nasal prosthesis with high histocompatibility must be selected for reoperation. At present, augmentation rhinoplasty with bone powder injection has long been eliminated in the world. Tips At present, the materials that can be selected for rhinoplasty are: autologous fat, hyaluronic acid and collagen.
