Cranial repair is a relatively routine procedure in neurosurgery, and it is also a very long-standing and currently classic procedure with very mature surgical techniques. During the long history, cranial repair materials have also evolved with the evolution, and now there are very good and excellent materials. In cranial repair surgery, the choice of better repair materials is an important factor in the outcome of the repair. At present, most of the repair materials used in most local hospitals for skull repair surgery are traditional titanium mesh materials. The metal titanium mesh material still has some shortcomings and defects, which may cause postoperative rejection and infection, wear the scalp, lead to material exposure, affect the postoperative CT MRI, including its heat insulation is not good, the patient may be more sensitive to the external hot and cold environment after surgery, resulting in discomfort, and so on many problems. Therefore, titanium mesh material is not a very ideal material for skull repair. At present, there is a more advanced material called polyether ether ketone PEEK, which has excellent performance and can overcome the above-mentioned problems of titanium mesh material, and has become a new trend of cranial repair material. Currently, our hospital is widely using this advanced material for cranial repair surgery, and the neurosurgery department is carrying out PEEK cranioplasty, which has been a great success in the clinical setting. What is the general cost of cranial repair? The cost cannot be generalized, it includes the cost of hospitalization, surgery, anesthesia, nursing care, medication, and of course the main factor is the cost of the repair material. Like polyetheretherketone PEEK material, although the cost will be relatively high, but its performance is excellent, the repair effect is very good, is completely worth it; while titanium mesh material, although the cost is low, but there may be a variety of problems, the loss is not worth it.
