The skull not only maintains the integrity of the head and face shape, but also is an important barrier connecting the skull and brain to the outside world. Cranial defects are mainly common after various traumatic injuries and debridement decompression, such as accidents, falling objects, craniofacial surgery, etc. Cranial bone defect should be promptly followed by cranial bone repair surgery, and cranial bone repair surgery should be done when the defect area reaches 3*3cm or more. There are also many patients ask the question of how much skull repair surgery costs. Cranial bone repair surgery is a common surgical procedure, and the cost of repair surgery is related to the examination fee, hospitalization fee, material fee and surgery fee. The purpose of the surgery is to take repair materials to make good repair to the defect area. Titanium mesh is currently used as a commonly used material for cranial repair, which is not expensive, but has great defects and poor postoperative results, so cranial repair also needs to choose more advanced repair materials. With the progress of modern technology, polyetheretherketone peek material has become the ideal choice for skull repair surgery, although the price of this material is a little more expensive, but the effect is very superior. At present, very few hospitals in China adopt polyetheretherketone peek cranial repair material as the basis of cranial repair implant material, while introducing the concept of plastic surgery, on the basis of 3D printing, for different patients to develop personalized peek cranial repair plastic surgery program, to achieve the appearance of repair plastic beauty.
