Skull repair has been changed and tested through the ages, and the preoperative, intraoperative and postoperative responses are now well established. Generally, the results are also good as long as the repair is performed in a local regular large hospital. However, clinical studies have found that some patients who choose titanium mesh cranial repair have many shortcomings such as high postoperative rejection infection, exposed titanium mesh, and asymmetry on both sides of the skull due to the use of metallic titanium as the implant material and the overlay repair method. Based on the deficiencies of traditional titanium mesh cranial repair, the medical profession has been focusing on theoretical and technical research and development of cranial repair, constantly summarizing the existing literature and hundreds of cases of cranial repair experience, upgrading and innovating the traditional cranial repair technology; at present, it has successfully completed the technical upgrade, upgrading the traditional titanium mesh cranial repair to peek material cranial repair plastic surgery, which draws on European and American countries With the new material polyether ether ketone peek as the skull repair implant material, its biological stability is much higher than that of traditional titanium mesh, and the postoperative rejection infection rate and rejection rate are much lower; secondly, the technology adopts embedded repair method to reduce the risk of material exposure; furthermore, it innovatively introduces the concept of plastic surgery and formulates personalized skull repair and appearance plastic surgery plan, with beautiful appearance and symmetry on both sides of the skull after surgery to achieve natural beauty. The effect is natural and beautiful. In fact, the cost of cranial bone repair surgery cannot be generalized. Because the cost of surgery cannot be measured by subjective assessment alone, it depends on the size of the damaged bone window.
