Whether the skull is intact or not is directly related to the health, but the accident has caused the skull to be damaged. After the cranial defect, the image aesthetics is affected is inevitable, more importantly, the brain tissue lack of hard bone protection, the cranial cavity environment is also greatly damaged, will cause a series of sequelae. For patients with cranial defects, timely cranial repair surgery to restore the integrity of the skull is an important guarantee of good health. In neurosurgery, cranial repair surgery has long been a routine surgery, patients do not need to worry too much about the risk of surgery, as long as you choose a regular hospital, skillful doctors and safe and effective repair materials, post-operative recovery will be very good. What are the best cranial repair materials in the country? Cranial repair surgery has evolved from ancient times to the present day, and there have been constant changes and advances in the use of repair materials. In the beginning, materials such as bone cement and plexiglass were used, which were relatively inexpensive, but with poor post-operative recovery, they have been slowly phased out. Then came the titanium mesh material. Compared with the materials of the past, the advancement of titanium mesh materials is undeniable, and the price is not too expensive, but a large number of clinical validations have shown that a series of problems may occur after surgery with titanium mesh materials. For example, some patients have had rejection reactions after undergoing surgery with titanium mesh materials, and there have even been cases where the materials have been exposed, and patients have needed to undergo a second surgery, which is more costly and painful. In this case, a more advanced material appeared, that is, polyether ether ketone PEEK material. The price of PEEK material is relatively higher, but it is directly proportional to the postoperative recovery effect. the performance of PEEK material is comparable to the human skull, with good thermal insulation, strong resistance to impact, and can also be personalized three-dimensional shaping, the recovery is ideal.
