Each organ of the human body has its own role, and each organ is irreplaceable. For example, the skull, which is the hardest bone in the body, protects the intracranial tissues and maintains the normal operation of the intracranial environment, but there are always many unknowable accidents and risks in life that may cause skull defects. Once the skull is damaged, the human health suffers a serious threat and it is important to undergo skull repair surgery in time. When it comes to skull repair surgery, the risk is a concern for patients. But patients do not have to be afraid, the current medical technology is very advanced, skull repair surgery is a relatively common surgical procedure, from ancient times to the present has thousands of years of development and precipitation, the technology has become more and more mature. Currently many hospitals are carrying out this treatment, but some local hospitals are not so good at it, and various hardware and equipment are not enough, and the materials used are different, so it has led to various bad problems for many patients after receiving skull repair surgery. For example, some hospitals now use titanium mesh material for skull repair surgery. Although the titanium mesh material has certain effect, many patients have the problem of infection and rejection after surgery, and some patients have the situation of material exposure after surgery, which requires secondary repair and patients suffer more. Moreover, the titanium mesh material will affect some post-operative examinations and is not considered an ideal repair material. Our experts use a new type of polymer material – PEEK material to perform skull repair surgery, which is safer and has a more ideal recovery effect after surgery, which is the ideal material for skull repair surgery, so patients can be assured of their choice. The PEEK cranioplasty, which has been carried out through continuous technical improvement, material optimization and design, and the introduction of the concept of cosmetic surgery, has achieved outstanding results in clinical practice and is highly praised and appreciated.
