Hello, in the early days of the development of cosmetic surgery, people used paraffin, tortoise shell, fishbone and animal bone for rhinoplasty. Practice has proved that these materials will produce various adverse reactions after being implanted into human body, so they have been abolished. In the future, doctors used ivory rhinoplasty to achieve good results, which once attracted people's attention. However, ivory is rarely used because of its excellent texture, time-consuming processing and difficult source.
