The importance of the skull is evidenced by the image of the skull as a fortress protecting the brain’s command. If the skull is damaged, the brain tissue is in danger. Nowadays, accidents can happen everywhere in life, so if the skull is damaged due to an accident, it is important to pay high attention to it and go to the hospital for skull repair surgery in time to avoid further damage. The key point of skull repair surgery is the choice of materials, the traditional repair materials are bone cement, plexiglass, etc. These materials have many defects and are basically no longer used in clinical practice. Later, many hospitals widely use titanium mesh material, which has certain progress and advantages over those materials in the past, but there are also some inevitable problems, such as post-operative infection, large rejection reaction, affecting post-operative CT magnetic resonance examination and so on. It is also because of the many defects that titanium mesh materials are not recommended for use now. The good news is that a new type of polyether ether ketone PEEK material has emerged, which has excellent performance and avoids the disadvantages of various materials in the past, and has a good postoperative recovery effect. The peek cranial repair material is from which country? peek materials were widely used in some foreign countries at first, such as the United States, Japan, Switzerland and Germany. However, with the continuous progress of Chinese medicine, there are now some hospitals in China that are able to use peek material for surgery, and we are one of them. Our team not only uses peek material, which has excellent performance, as the skull repair material, but also constantly improves and upgrades the technology and optimizes the design of the material, and innovatively introduces the concept of cosmetic surgery to carry out comprehensive PEEK skull repair and plastic surgery, which not only completes the skull structure, but also is more beautiful and good-looking.
