Cranial repair surgery is a routine procedure in neurosurgery, but also a very long history, very classic surgery, as early as thousands of years ago, our ancestors were carrying out such surgical practice, the development of today, the technology has been very mature. Currently among the modern medical environment. Craniofacial repair surgery is carried out more and more mature, and the cranial repair material is one of the factors that have a greater impact on the effect of the repair. 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 of the 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 more excellent, it is basically very close to the performance of the human skull. Whether it is from the hardness of the material, elasticity, thermal insulation, ray transmission, tissue compatibility, as well as shaping effect, are very ideal. In fact, peek cranial bone repair is still far from being popularized. There are not too many hospitals in the country that apply this new material for cranial bone repair, but we have widely used this advanced polyether ether ketone PEEK material to implement PEEK cranial bone repair and plastic surgery, and have achieved great success in the clinic. The team not only adopts this advanced material, but also continuously carries out technical innovation, optimization design of the material, and introduces the concept of aesthetic plastic surgery, and carries out personalized and fine optimization adjustments in terms of improving comfort, increasing blood flow, maintaining tissue activity, and enhancing aesthetics, etc., so as to achieve the organic unity of aesthetically pleasing appearance, anatomical integrity, and functional perfection, which has been widely recognized and highly praised by the majority of patients and their families.
