Cranial defects are a relatively common disorder and are often encountered in neurosurgical practice. Among the patients with cranial defects, a considerable number of them are caused by various accidents, such as accidental traffic accidents, accidental production safety accidents, accidental falls from height, accidental thrown objects and so on, which may cause serious cranial injuries and may leave cranial defects after craniofacial surgical treatment. How does the insurance company pay for skull repair in an accident? The question of how to pay for skull repair due to an accident depends on what kind of insurance the patient has purchased, the amount of coverage, the specific terms of the contract, and the policy standards of the place where the accident occurred. How to pay for skull repair is one of the issues, and how to do skull repair is also an important issue that needs to be carefully considered by the patient. For skull repair, the choice of repair material and the choice of hospital doctor are two very important issues. Although this material is advanced, there are still some problems in clinical use, which is not very ideal. For example, titanium mesh may cause rejection infection, abrasion of scalp, material exposure, collapse and deformation, sensitivity to external environment, hot and cold, and affect CT magnetic resonance examination, etc. Therefore, it is not recommended to use titanium mesh material for skull repair. Now there is a new type of polyetheretherketone PEEK material, which has excellent performance and is comparable to autologous cranial bone, and can effectively avoid the above-mentioned problems that may arise from titanium mesh material and achieve ideal repair results. Of course, in addition to good repair materials, surgical technique is also very important, requiring extensive clinical experience in neurosurgery, excellent surgical skills, and the ability to deal with various problems intraoperatively. Our team not only applies the excellent performance of polyether ether ketone PEEK as the cranial repair material, but also constantly improves and upgrades the surgical technique and optimizes the design of the repair material, and now has 4 like technical innovation, the team also innovatively introduces the concept of aesthetic plastic surgery, so as to carry out comprehensive PEEK cranial repair plastic surgery, which can achieve structural restoration, anatomical integrity, functional perfection, and aesthetic appearance of the unity. It is well received and recognized by the majority of patients with cranial defects and their families.
