PEEK is a new trend in cranial repair materials. peek is a new type of special polymer material, its properties are very close to the human autologous cranial bone, in clinical applications with excellent results. peek material has very good histocompatibility, basically no rejection; peek material is based on the patient’s cranial CT data for three-dimensional shaping, highly restored cranial physiological structure; peek cranial is embedded in the repair, the smooth appearance of the good cranial bone repair will not produce the cutting injury as titanium mesh overlay repair; peek material radiolucent, does not affect the surgery. The PEEK material is shaped in three dimensions according to the patient’s cranial CT data, highly restoring the physiological structure of the skull; the PEEK skull is embedded in the repair, and the appearance of the repaired skull is smooth and does not produce cutting injuries like those caused by titanium mesh-covered repairs; the PEEK material has good radiation transmission and does not affect postoperative medical examinations; in addition, the PEEK material is comparable to human skull in terms of elasticity, strength, thermal insulation, stability, etc., and is a very ideal skull repair PEEK is an ideal material for cranial repair. We currently use this advanced polyetherether peek material for skull repair and have achieved great clinical success. The cost of peek treatment is related to many factors, including the cost of hospitalization, surgery, anesthesia, nursing care, medication, and of course the more important one is the cost of skull repair material, and the cost of skull repair material is mainly related to the size of the skull defect, the larger the defect area, the more material will be needed, and the cost will be higher. The larger the defect area is, the more materials are needed and the higher the cost will be. Therefore, this needs to be evaluated according to the patient’s own specific situation. But the overall cost is not too high. We use new polyetheretherketone peek material, and constantly carry out technical improvement and innovation and material optimization design, and also innovatively introduce the concept of cosmetic plastic surgery, so as to carry out comprehensive peek cranial bone repair, which can achieve good results of anatomical integrity, perfect function and beautiful appearance, and obtain good clinical feedback, which is unanimously recognized and praised by the majority of patients and their families.
