Cranial repair surgery is a surgical procedure to repair cranial defects caused by various reasons. The main purpose is to reconstruct a closed and complete cranial cavity and to solve or improve the problems of cerebrospinal fluid circulation disorders, blood circulation disorders, and neurological deficits. Cranial repair surgery is a routine and common procedure in neurosurgery, and the technique has become very mature. Patients with cranial defects should undergo cranial repair in a timely manner, because if not repaired, cranial defects can have many adverse effects on the human organism, and some can even be life-threatening. Some patients ask how much all the costs of cranial bone repair surgery are. In fact, the cost is not fixed, because the total cost includes many aspects, such as the cost of hospitalization, surgery, anesthesia, nursing care, medication, etc. Of course, there is an important part of the cost. Of course, another important aspect is the cost of repair materials. Generally, the regular hospitals in China will charge fairly and reasonably according to the relevant national laws and regulations. The cost of cranial repair materials has a big impact on the total cost. The cost may vary for different materials. For example, the titanium mesh material commonly used in clinical practice, the cost of this material may be slightly lower, but its performance is not very ideal, and it may cause various problems after surgery, such as post-operative infection and rejection, scalp wear, material exposure, affecting CT MRI, post-operative sensitivity to hot and cold environment, dizziness and headache, and so on. And there is a new type of polyetheretherketone PEEK material. This material is ideal for overcoming the above-mentioned problems that may arise with titanium mesh materials, and has achieved very good results in clinical practice. We widely carry out PEEK cranioplasty, not only the application of advanced and ideal PEEK material, but also the continuous improvement and upgrading of surgical techniques, optimization of material design, and the introduction of the concept of aesthetic plastic surgery, can achieve anatomical integrity, functional perfection, beautiful appearance of good results, by the majority of patients recognized and praised.
