The noses of East Asians are slightly flat and somewhat sunken, unlike those of white people. White people have the most common hunchback, while Asians have the most common flat nose. If the condition of the back of the nose is ok, sometimes the simplest hyaluronic acid will be used for rhinoplasty, and a small range of improvements will be made to achieve the effect of natural beauty. If the back of the nose collapses too much, or even the bridge of the nose is crooked, the operation that needs to be done at this time depends on the situation. If you have a crooked nose and hunchback, you need to modify the nasal bone at the same time, including chiseling the nasal bone to straighten the back of the nose and the bridge of the nose. After removing the hump, a prosthesis can be used to increase the nasal dorsum. Prosthesis includes silicone rubber implant, expansion implant and costal cartilage implant, which can increase the height of nasal dorsum and rely on the tension of skin. Because sometimes some people's own skin tension is relatively small, that is, the skin is very tight. At this time, when implants are implanted, doctors are worried about the common situation, that is, because the tension is too great, the skin behind the nose will be worn through. Sometimes, patients are advised to pinch the local skin before operation. 1-2 months later may have a good effect. There are also some people who have thin skin behind their noses. At this time, when they implant the prosthesis, they will feel transparent, which means that under the sunlight, the bridge of the nose and the top of the back of the nose appear transparent. At this time, some posterior auricular fascia or costal fascia can be implanted to wrap the prosthesis to make the shape of the nasal dorsum more natural.
