Nowadays, transportation is becoming more and more convenient, but some traffic accidents are also frequent, and many people suffer from cranial damage due to some traffic accidents. Damaged skull is not a small problem, only with skull repair surgery can you regain your health. There are many materials used for skull repair, for example, titanium mesh is a material used in many local hospitals. Is titanium mesh for skull repair metal? Many people don’t know much about titanium mesh, so they have all kinds of doubts in their mind. It is understood that titanium mesh is a non-corrosive metal, which is better than earlier materials such as plexiglass and bone cement. Titanium mesh is hard and lightweight, and because it is non-corrosive, it can help resist secretions from the body. There are limitations to the use of titanium mesh for cranial bone repair surgery, as its ability to insulate against temperature is relatively poor, and its ability to conduct heat can cause significant scalp irritation, among other problems. In the application of cranial repair surgery materials, some hospitals use a newer material – PEEK material, which has almost all the advantages of various cranial repair materials, avoiding the defects of a variety of cranial repair materials, to become the ideal repair material for cranial repair surgery. PEEK material is relatively stable, high thermal insulation, biocompatibility, hardness and elasticity, etc. are superior to titanium mesh, and the performance of the autologous skull is comparable to that of a very advanced special polymer materials. Moreover, PEEK material can carry out personalized three-dimensional reconstruction according to different patients’ conditions, and highly restore the patients’ cranial structure, the effect is very realistic, and it is the preferred material for cranial bone repair surgery at present. Of course, the success of cranial repair surgery, in addition to choosing a good hospital, experts and materials, post-operative care work should also be done seriously. After cranial repair surgery, patients should pay attention to keep the skull area clean and dry, ensure sufficient sleep, light diet, etc., which is more conducive to recovery and get a good postoperative effect.
