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 prompt cranial repair is needed. Cranial repair surgery, the 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. At present, polyether ether ketone PEEK material is a very good cranial bone repair material, fully in line with the national standards for human implants, its performance is basically comparable to the autologous cranial bone, and the tissue compatibility is very good, and will not have any effect on the growth and development of children. Moreover, our neurosurgery team not only adopts this PEEK material, but also continuously carries out the optimized design and technical innovation of the material, and also introduces the concept of cosmetic plastic surgery to carry out refined and personalized cosmetic treatment for the factors affecting the appearance and shape of the patient, and has achieved the good effect of structural integrity, perfect function, and beautiful appearance, which is well recognized and praised by the patients and their families.
