In the current life is full of accidents everywhere, a fall from a height, a traffic accident will bring different degrees of damage to our body, such as a missing piece of skull. We all know very well that the skull is the protective layer of the brain tissue, the missing skull not only affects the appearance of the aesthetic, but also will bring irreversible damage to our health. In children, it is possible to grow back a small area of missing skull bone, but if the missing area is too large, it is unlikely to grow back on its own, and in adults, the possibility of self-healing is unlikely to be high if there is a missing skull bone. So don’t take any chances and go to the hospital to have a skull repair surgery in time. Regarding the skull repair surgery, the choice of material is a very critical issue, many hospitals commonly use titanium mesh material for skull repair surgery, although it has a certain effect, but there are also many shortcomings of this material. For example, postoperative rejection reaction, affecting the future of the CT nuclear magnetic examination, the material is exposed to the need for secondary repair, etc., the patient is doubly painful and helpless. It is in the patients’ discouragement and despair that a new type of polyether ether ketone material, also known as PEEK material, came into being. PEEK material has certain uniqueness and advancement, and its properties are comparable to those of autologous skull, and it can also be personalized according to the patient’s cranial structure to carry out 3D design and customization, which can highly restore the patient’s cranial shape, and the effect of the postoperative period is very beautiful. Our team is to use this material to carry out surgery, and we continue to improve the technology innovation and material optimization design, successfully introduced the concept of cosmetic plastic surgery, comprehensive PEEK cranial bone repair plastic surgery, and has achieved outstanding results.
