Compliance is a prerequisite

选用有注册证、可追溯的医用material，拒绝来源不明或禁用产品。机构应能提供材料信息。

Common material categories

• prosthesis（如silica gel、expanded）：工业化生产，可追溯；

• 自体cartilage(Ear/nasal septum/rib): Taken from yourself, no rejection, but materials need to be taken;

• The specific one to choose depends on the plan and personal conditions.

avoid the pit

Do not believe in absolute publicity such as "permanent","traceless" and "non-invasive"; the name, brand and batch of the material confirmed before surgery can be checked. Safety is better than low price.

prompt

Material selection is a medical decision, so please make a face-to-face evaluation.

Material safety is subject to compliance agencies and doctors.
