With a skull defect, the area of the defect will collapse or bulge out, with a noticeable swelling and pain, and the whole head will not look so beautiful. Furthermore, a skull defect can lead to extremely unstable intracranial pressure, which can lead to a variety of problems and may be life-threatening. Therefore, cranial bone repair surgery should not be ignored. Since the development of medicine, cranial repair surgery has been a relatively routine surgery, and the technology has been very mature. In order to get a better repair effect, the choice of the material used by the surgeon plays a very important role. Which material is better for cranial repair? Cranial bone repair materials traditionally include bone cement and plexiglass, but these materials have too many defects and have long been eliminated. Nowadays, most hospitals use titanium mesh, which is an improvement over the previous materials, but still has many drawbacks and shortcomings. For example, after the operation, patients will have obvious rejection reaction, easy to infection; after the operation is easy to titanium mesh exposed problem, but also need to repair again; there is the use of titanium mesh repair skull will affect the postoperative ct MRI examination and so on. Therefore, in order to repair once in place, or should choose a more advanced and effective material, peek material is currently a good material to do skull repair surgery. peek material is very good to avoid the shortcomings of titanium mesh and other materials, its various properties are excellent, and the autologous skull is comparable to the postoperative worry-free, peek material originated from foreign countries, we use peek material, constantly innovate the technology, pioneered the unique PEEK cranial bone repair and plastic surgery, with four technical innovations, the optimization of the design of the PEEK material, surgical techniques to improve and upgrade, and introduce the concept of cosmetic plastic surgery, for many patients. With 4 technical innovations, optimized design of PEEK material, improved and upgraded surgical technique, and introduction of cosmetic surgery concept, we have successfully repaired the skull and restored the beauty for many patients, with excellent and trustworthy effect.
