Cranial repair is a relatively routine procedure in neurosurgery and has been developed over thousands of years in the history of medicine. The effectiveness of the repair is not only at the surgical level, but also at the level of the repair material. For example, the titanium alloy material, which is widely used in clinical practice, is more advanced and mature, but still has some problems and is not very ideal. In recent years, skull repair materials have undergone many improvements and innovations, and are becoming more and more advanced. At present, the more commonly used cranial bone repair material is titanium mesh, which has made great progress compared with the traditional material, but it is not particularly ideal, and there are still some problems. So what are the advantages and disadvantages of titanium mesh for cranial repair? Compared to traditional materials, titanium mesh has its advantages, but compared to the more advanced polyether ether ketone (PEEK) materials, the disadvantages of titanium mesh become apparent. Of course, one of the advantages of titanium mesh over PEEK is that it can be slightly less expensive. But its disadvantages are indeed many, such as titanium mesh is a metal material, higher thermal conductivity, insulation performance is not good, may cause sensitivity to hot and cold reactions: in addition may cause patients chronic pain, subcutaneous fluid more; this metal material will also affect the future to do a variety of medical examinations, such as CT nuclear magnetic ah, will appear artifacts, causing diagnostic interference in addition to titanium mesh tensile lightness, stability, elasticity, etc. also have a large Differences. If conditions allow, it is recommended to do this polyetheretherketone repair. Professor Zhu Anlin’s team at the Department of Neurosurgery for Cerebrovascular Diseases of the Civil Aviation General Hospital has used this advanced PEEK material to achieve excellent repair results, which have been well received by patients from all over China. In addition, the PEEK material is a bionic material that can be used to repair the skull. In addition, this PEEK material is bionic bone, which can fully restore the anatomical structure of the skull and can be highly compatible with the autologous skull, and is comparable to the autologous skull in terms of elasticity, heat transfer, hardness, and stability, especially for pediatric patients, and can better adapt to the growth and development of the autologous skull.
