The skull plays a key role in the human body, maintaining the integrity of the head and face shape and protecting an important barrier between the cranium and the outside world, but it is possible for the skull to become defective. Skull defects are mainly common after various traumatic injuries and debridement and decompression surgeries, such as accidents, falling objects, and cranio-cerebral surgeries. If the area of cranial defect reaches more than 3*3cm, it is unquestionable to do cranial bone repair surgery only so that more injuries and complications can be avoided in time. However, many patients do not know much about cranial repair surgery, such as the materials used for the repair and the full cost of cranial repair surgery. Cranial Repair Surgery is a common surgical procedure, the cost of repair surgery is related to the examination fee, hospitalization fee, material fee and surgery fee, the purpose of the surgery is to take the repair material to repair the defective area in a good way. Titanium mesh is currently used as the most commonly used cranial bone repair material, its price is not high, but there are great defects, the postoperative effect is not good, so cranial bone repair also need to choose more advanced repair materials. With the progress of modern science and technology, polyether ether ketone peek material has become the ideal choice for cranial bone repair surgery, the price of this material is a little more expensive, but the effect is very superior. The peek material has its properties are very close to the human bone, after the repair of cranial stress integrity. Low rejection and high stability. Simply put, this material is more “compatible” with the body’s tissues, with no metallic heat or cold conduction reactions, effectively preventing temperature imbalances within the skull and not affecting future medical imaging, such as CT or MRI.
