The integrity of the skull is so important for the health of the body, but many people in life have serious damage to the skull due to an accident. After skull defect, the brain tissue is not protected by the shell of the skull, and the danger is really approaching step by step. Therefore, patients should pay attention to the seriousness of skull defect and go to the hospital for skull repair surgery before it is too late. However, on the issue of skull repair surgery, the choice of repair material is directly affected by the post-operative recovery effect, so patients must learn more about it. From the clinical point of view, many hospitals are now doing skull repair surgery using titanium plate material, titanium plate material compared with those materials in the past is a certain degree of progress, but what about titanium plate repair skull surgery? The original titanium plate material has these defects: 1, because the titanium plate material is a metal material, metal thermal conductivity is relatively strong, the patient will be more sensitive to the external hot and cold environment after surgery. 2, many patients may have different degrees of infection after receiving titanium plate material surgery, and there are many physical symptoms of discomfort. 3, the use of titanium plate material will interfere with the transmission of radiation, interference with the magnetic field environment, postoperative patients do CT examination and magnetic resonance examination, etc. will have some impact. 4, titanium plate material is mainly used to cover the repair method, the edge of the material will cause harm to the patient’s scalp, the patient will have obvious pain, and even some patients have the situation of material exposed after surgery. The use of PEEK has broken down the defects of titanium plate material, and its performance is excellent, and the postoperative recovery is ideal. Our team is currently using this material for skull repair surgery, and we are constantly improving and upgrading our technology and optimizing the design of the material, successfully introducing the concept of cosmetic surgery, making the postoperative results more natural and aesthetically pleasing.
