The role of the skull is obvious, it is a set of very hard bones, it is like a helmet for the brain, maintaining the normal operation of all life activities in the skull. But in real life, there are too many risk factors that can lead to cranial defects. Once the cranial bone is damaged, the brain loses its hard protective barrier, and the consequences are more serious if it is not treated in time. Cranial defect affects the image on the one hand, on the other hand, when the cranial defect, the original closed cranial environment is also destroyed, the intracranial pressure becomes unstable, and will lead to the emergence of cranial defect syndrome, many patients said they often have headaches and dizziness, emotional irritability, they have no sense of security, if the accident occurs again, the danger is even greater. Cranial defect can not be ignored, the defective part usually can not grow up by itself, only early cranial repair surgery can restore the complete anatomical structure of the skull as soon as possible, the cranial life activities can also function normally. However, it is important to choose really good materials for skull repair surgery, as the recovery effect after surgery will be more ideal and patients will suffer less. What is the best material for skull repair and how much does it cost? Cranial bone repair surgery has a history of thousands of years, and the repair materials have been constantly changing and evolving, currently most hospitals use titanium mesh material, which is still relatively inexpensive, but titanium mesh material also has certain defects and shortcomings, and does not achieve the ideal treatment effect. We now use polyether ether ketone peek material is more advanced and ideal, which is a very safe polymer material, hard and elastic, good stability, high tissue compatibility, to make up for the many shortcomings of the titanium mesh material, the price will be more expensive, but with the effect is proportional!
