Cranial repair surgery is a routine and classic procedure in neurosurgery, which was practiced by our ancestors thousands of years ago, and has developed into a highly sophisticated technique today. Currently in the modern medical environment. Cranial repair surgery is carried out more and more mature, and the cranial repair material is a factor that has a greater impact on the repair results. Clinically the most widely used cranial bone repair material is titanium mesh material, this material compared to some earlier traditional materials, some of its performance is advanced. However, titanium mesh material also has some defects and shortcomings. Postoperative rejection, infection, wear and tear of the scalp, resulting in the exposure of the material, the material is not hard enough, easy to collapse and deformation by external forces, or to affect the nuclear magnetic ct examination, there is also this material does not insulate the heat, the patient may be more sensitive to the external hot and cold environments after the operation, resulting in discomfort and so on some problems. At present, the more advanced, more ideal effect of the material should be the new polyether ether ketone material. The performance of this material is even better, and it is basically very close to the performance of human cranium. Whether it is from the hardness of the material, elasticity, thermal insulation, ray transmittance, tissue compatibility, as well as shaping effect, are very ideal. So has peek material cranial bone repair become popular? In fact, peek material cranial bone repair is still far from reaching the level of popularization. Nationally, the application of this new material for cranial bone repair hospital is not too much, at present we are widely used PEEK material for cranial bone repair, the application of this advanced polyether ether ether ketone PEEK material PEEK cranial bone repair plastic surgery, in the clinic has achieved great success. And the introduction of the concept of cosmetic plastic surgery, in improving comfort, increase blood flow, maintain tissue activity, enhance aesthetics and other aspects of personalized fine optimization adjustments can be achieved in beautiful appearance, anatomical integrity, functional integrity of the organic unity of the majority of patients and their families are widely recognized and praised.
