The skull is the protective shell of the soft tissues of the brain and maintains the stability of the intracranial environment. Once an accidental skull injury occurs, the intracranial brain tissue is at great risk. Cranial injuries brought about by some accidents in life often have a negative impact on the patient’s psychology and body. It is the common wish of patients to choose cranial bone repair surgery; the cost of cranial bone repair surgery is the concern of all patients. Cranioplasty is different from normal neurosurgery. It should be expensive to operate on such a critical part of the head, right? No, cranial bone repair is just a type of regular neurosurgery. Unlike what most patients think, the cost of cranial bone repair does not depend on the type of surgery, but rather on the materials used for the surgery. Prices vary depending on the material used for the repair. Traditional materials, such as calcium phosphate bone cement, were initially sought after by patients because of their low cost. In the long-term clinical application, a large number of patients had incurable complications. And then appeared titanium mesh material, the price is not high, but there will still be a series of complications, although the application of a wide range, but the adverse reactions brought about by the majority of patients have palpitations. The current use of PEEK repair materials, although the price is high, but based on the characteristics of high-performance molecular materials, PEEK’s clinical effect is incomparable to other materials. Can be highly compatible with the autologous skull, and in terms of elasticity, heat conduction, hardness, stability and other aspects are comparable to the performance of the autologous skull, especially for pediatric patients, he was able to better adapt to the growth and development of the autologous skull. Although the choice of PEEK material as a cranial bone replacement, but can be for many patients to avoid the pain of the aftermath of the trouble.
