Cranial repair is a relatively routine procedure in neurosurgery and has been performed for thousands of years. It has been found that our ancestors were practicing this kind of surgery thousands of years ago, and then after thousands of years of development and progress, cranial repair techniques have become very mature with the current medical conditions. People should go to the hospital for cranial repair surgery in time if they have suffered a cranial defect due to various risk factors. With the continuous development of cranial repair technology, cranial repair materials are also undergoing continuous innovation and upgrading. At the same time, cranial repair material is also a factor that has a great influence on the effect of cranial repair, good repair material can achieve more ideal repair effect, while if the repair material is not ideal, then it is likely to produce various problems after surgery. One kind of cranial bone repair material that is widely used clinically in general hospitals all over the country is titanium plate material. This is a metal material, although it is widely used, and compared to the traditional material before, it still has some advanced, but this material is not very ideal, there are some defects and shortcomings, such as possible postoperative infection rejection and other phenomena, may wear the scalp, resulting in scalp ulceration, titanium plate exposed, there is a possibility that affect the postoperative patients to receive ct nuclear magnetic examination The titanium plate material is not insulated, so the patient may be more sensitive to the external hot and cold environment after surgery, resulting in discomfort; and the hardness of the titanium plate is not enough, easily deformed by external forces, resulting in scalp collapse and other problems. What about the exposed titanium plate for skull repair? The exposed titanium mesh can be repaired twice, but of course, we need to choose good materials. At present, our team widely uses new polyether ether ketone peek material to carry out peek cranial repair plastic surgery, through continuous technical improvement and innovation, material optimization design, the introduction of the concept of cosmetic plastic surgery, so that we can achieve the organic unity of anatomical integrity, functional perfection and beautiful appearance, and achieve the ideal cranial repair effect, which is recognized and praised by the majority of patients with cranial defects and their families.
