The skull is intact for a better facial image and a hard protective barrier for the cranial tissue. However, every day in life there are accidents, such as car accidents, falling objects, etc. These accidents can easily lead to skull damage. After skull defect, not only the image is damaged, but also a series of health problems will be caused, and the patient’s body and mind will be traumatized, so we must pay attention to it. For cranial defects, it is indisputable that cranial bone repair surgery should be done in time to avoid more problems. The price of cranial repair is a concern for many patients, because they do not know much about cranial repair surgery, and they worry that the price is too high for them to afford. In fact, cranial repair surgery is a routine surgical procedure, and the cost of surgery is not very high, which usually includes examination cost, surgery cost, hospitalization cost, material cost and so on. The size and severity of the skull defect are different for each patient, and the final cost is also very different. Patients should not worry too much about the cost, it is crucial to find a regular hospital in time and take effective materials for repair with the help of professional doctors. In the past, bone cement and animal bone were mostly used for skull repair surgery, and these materials are low cost but have great post-operative side effects and are no longer recommended. Later on, titanium mesh material was widely used. The benefits of this material are there, but there are also many disadvantages, many postoperative rejection reactions, and there is also the problem of material exposure, so the choice remains to be examined. With the progress of science, the ideal material for skull repair surgery is PEEK, which has excellent properties and overcomes the problems of traditional materials. The neurosurgery team at our hospital has widely adopted this advanced material and has continued to make technical improvements and optimize the design of PEEK materials, and now has four technical innovations, as well as introducing the concept of aesthetic plastic surgery, which has led to outstanding clinical results in PEEK cranial repair and plastic surgery, and the fees are not high, which is recognized and praised by patients with cranial defects and their families.
