Cranial repair is a relatively routine neurosurgical procedure that 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 satisfactory. In recent years, skull repair materials have undergone many improvements and innovations, and are becoming more and more advanced. At present, the titanium mesh is the more commonly used cranial repair material in clinical practice. This titanium mesh material has made great progress compared with the traditional material in the past, however, it is not particularly ideal and still has some problems. What are the advantages and disadvantages of titanium mesh for skull repair? Compared to traditional materials, titanium mesh has its advantages; however, when compared to the more advanced polyether ether ketone (PEEK) materials, the disadvantages of titanium mesh become apparent. Of course, one advantage 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, titanium mesh tensile lightness, stability, elasticity, etc. also have a large Differences. If conditions allow, it is still recommended to do this kind of polyetheretherketone repair. Professor Xingbing’s team has used this advanced PEEK material to achieve excellent repair results, which have been well received by patients from all over the country. The repair material used in the cranial repair is the most advanced PEEK material available. 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, stability, etc., especially for pediatric patients, which can better adapt to the growth and development of the autologous skull.
