The skull is an important part of the human skeleton, it is a barrier to protect the brain tissue from external aggression. However, cranial defects are very common in today’s life, which not only affects the aesthetic appearance, but also poses a certain threat to health, so it is not a good idea to be careless, and it is wise to have cranial bone repair surgery before it is too late. At present, many hospitals have carried out this kind of surgery, but there are differences in the use of surgical materials. Some local hospitals use titanium mesh materials for surgery. Compared with earlier repair materials, titanium mesh materials have indeed made some progress, but they also have many shortcomings and deficiencies, which are worth paying attention to. Titanium mesh repair skull will be the same as the previous skull? Many patients are concerned about this issue, after a large number of surgical cases show that the titanium mesh material is not very good tissue compatibility, and the autologous skull is still a certain difference, and a lot of patients after the operation of rejection, postoperative infection, material exposure, material deformation and so on. Therefore, titanium mesh material is not the ideal choice for cranial bone repair. If you want to get a better effect of cranial bone repair, it is recommended to use the new polyether ether ketone PEEK material, which is a very safe polymer material with strong stability, high elasticity, and good thermal insulation, comparable to the autologous cranial bone, and it is the best choice for the cranial bone repair surgery at present.
