The skull is a very important organ in the human body, it plays an important role in protecting brain tissue and maintaining normal intracranial pressure, however, there are still some people who suffer from skull defects for various reasons in their lives. However, there are some people who have skull defects for various reasons. In fact, in today’s developed medical environment, cranial repair is already a relatively routine surgery in neurosurgery, which is not complicated and not very difficult, so it is not a big surgery. However, the material used for cranial repair is very important. Although the titanium mesh material, which is widely used in clinical practice, is much more advanced than other traditional materials, there are still many problems or complications that affect the repair effect and restrict the quality of life of patients in the future. Currently, the most… The newest polyether ether ketone (PEEK) material has been used to repair the skull, achieving unprecedentedly good results. “The three-dimensional reconstruction technology of this PEEK material can perfectly restore the physiological structure of the skull according to the patient’s cranial CT data and precisely fit the defective bone window. In addition, the performance of this material is comparable to that of autologous skull in terms of elasticity, thermal insulation, hardness, stability, etc. It is a perfect cranial bone replacement material without foreign body reactions or interference with future radiological examinations .” Basically, it can be said that after the repair with peek is completed, it is not much different from the patient’s own cranial bone. According to the current advanced technology of cranial bone repair we have finished elaborating, and we hope that our patients and friends will be aware of it and get well soon with early treatment.
