Craniosynostosis is a relatively common craniosynostosis in neurosurgical practice, and the age of onset of this disorder is relatively discrete. In many children, craniosynostosis can occur as a result of car accidents, falls from height, or craniotomies for craniosynostosis. Cranial defects can have many adverse effects on the human body, so cranial repair is needed in a timely manner. Cranial repair surgery, repair material is a more important influence factors, the current clinical use of materials, polyether ether ketone PEEK material is a new type of polymer materials, excellent performance, and gradually become the new trend of cranial repair materials. As a new material with excellent performance, PEEK material will not affect the development of children. Of course, it has a lot to do with the choice of cranial bone repair material. The skull is the hardest bone in our body, because of the protective barrier of the skull, our brain tissue can work and function normally. However, accidents are unavoidable and many people suffer from cranial defects due to accidents, which can be very harmful to their health. The only way to avoid further damage is to undergo cranial repair surgery. The first thing to consider about skull repair surgery is the material used for the repair. From the past to the present, the use of materials for skull repair has been constantly revolutionized. In the beginning, bone cement and plexiglass were used, but after many surgeries, these materials have been proven to have some problems and have been slowly eliminated. Later on, titanium mesh materials were used, but although they have their progress, they still have defects and shortcomings. In order to achieve a better effect of skull repair, there is now a more advanced material, that is, peek material. peek material is a polymer material, all aspects of the performance of the human skull is comparable to the human skull, and can be based on the patient’s head shape three-dimensional molding design, highly restore the skull structure, the patient will not appear after the operation of the phenomenon of xenophobia, do not have to worry about the infection problem, it is the current very ideal material to do cranial bone repair surgery. It is the ideal material for cranial repair surgery. The peek material repair effect is good, there are many advantages, some patients will worry about the price problem. peek material than those traditional repair material price will be a little higher, but the effect can be achieved is reputable. In addition, each patient’s skull damaged area is not the same size, the cost is not the same. At present, polyether ether ketone PEEK material is a very advanced cranial bone repair material, fully compliant with the national standards for human implants, its performance is basically comparable to the autologous cranial bone, tissue compatibility is very good, and will not have any impact on the growth and development of children. We not only use this advanced PEEK material, but also continue to optimize the design of the material and technological innovation, but also introduce the concept of cosmetic plastic surgery, the patient’s factors affecting the appearance of the shape of the fine, personalized cosmetic treatment, has reached a structural integrity, functionality, aesthetic appearance of the good results, widely recognized and praised by patients and their families.
