Cranial repair surgery has been developed for thousands of years in the history of medicine, and the surgical technique has been relatively mature. Skull repair materials have also undergone many improvements and innovations, and are becoming more and more advanced. The titanium mesh is the most commonly used cranial repair material in clinical practice, which has made great progress compared with the traditional materials in the past, however, it is not particularly ideal and still has some problems. Compared with traditional materials, titanium mesh has its advantages; however, when compared with 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 difference. Therefore, if conditions permit, it is still recommended to do this polyetheretherketone repair. We use this advanced PEEK material to achieve very good repair results, and gain the recognition and praise of patients.
