Accidents always come when we are not paying attention, and there are many people around us who suffer from one kind of problem such as cranial defect due to one accident or another. In the event of a skull defect, cranial repair is required. Cranial repair surgery is a routine procedure that is often required in neurosurgery. This procedure is also very old and classic. Thousands of years ago, our human ancestors were performing attempts at cranial repair. Through continuous development and evolution, cranial repair surgery techniques have become more and more mature, and repair materials have followed newer advances, from the beginning of fleece and metal pieces, to later plexiglass, bone cement, silicone, etc., and then to the current commonly used titanium mesh and polyetheretherketone PEEK materials, all the way to better and better material performance and more and more ideal repair results. At present, polyetheretherketone PEEK material is a cranial repair material with very good performance and relatively better results, favored by neurosurgeons and the majority of patients with cranial defects. So what is the price of peek material cranial bone repair? When it comes to repair surgery, there are many patients who are concerned about the cost of treatment. The cost of PEEK material is relatively high, but the cost is well worth it because of its excellent performance and good postoperative results.
