The skull is like a protective wall for the brain, protecting the brain tissue from external damage. However, the occurrence of cranial defect breaks the balance of all this, and the cranial tissues lack the protection of solid cranial bone, which may be dangerous at any time. In order to restore the integrity of the skull as soon as possible, and for safety reasons, it is important to go to the hospital for skull repair surgery. What are the risks of skull repair surgery? The risks of surgery are a concern for every patient, after all, surgery on the head can be a little scary. However, cranial repair surgery has been in existence for thousands of years and is truly ancient and classic. After a long time of development and progress, and with better and better medical conditions, cranial repair surgery is now a routine procedure in neurosurgery, and the technique has become more and more mature, so patients need not panic. However, the choice of material is very important in skull repair surgery, if the material is not good, the postoperative effect will be greatly reduced. At present, many hospitals commonly use titanium mesh material, which is a kind of metal material and has progressed compared with some materials in the past, but there are still certain defects and shortcomings in clinical use, such as postoperative infection and rejection, scalp wear, force collapse deformation, sensitivity to external hot and cold environment, material exposure and so on. In fact, after the titanium mesh material, there is now a more ideal repair material, which is polyether ether ketone PEEK material. This is a very advanced polymer material, its performance is much better than the titanium mesh material, and more compatible with the autologous cranial bone, but also to avoid the titanium mesh material after surgery may appear all kinds of problems, bringing a very good repair results. However, there are not many medical institutions in China that can perform surgery using PEEK material. Our team is using this material extensively, with many clinical cases and experience, and has successfully helped many patients solve their problems. The team also continues to improve and upgrade technology and material optimization design, and innovatively introduces the concept of aesthetic plastic surgery to carry out comprehensive skull repair plastic surgery, which is more natural-looking after surgery.
