Is there still a risk in skull repair? Life is always full of accidents, and one accident can lead to damage to our skull, and to reduce the occurrence of more dangerous situations, skull repair is necessary once the skull is extensively damaged. Cranial repair, to the layman’s eye, sounds like a big job and a seemingly risky procedure, so care must be taken in choosing materials. In the beginning, experts were blind in their search for cranial bone materials. With the continuous development of science and technology, titanium mesh is widely used as a repair material in more hospitals, but there are still many defects and shortcomings, causing patients to have different degrees of rejection after surgery. In this dilemma, more and more medical experts realize that it is not enough to fill the cranial defects for cranioplasty, but it must achieve the reconstruction of the local anatomy of the skull surface. Therefore, for a more perfect repair material, they have been exploring …… So, has the exploration come to fruition so far? Are there still risks in cranial bone repair? What is the success rate of the surgery? The cranial bone repair has undergone a thousand years of development and has now come to a very mature stage. The cranial bone repair material is made of a new polyether ether ketone material, commonly known as PEEK, which has a very high surgical success rate, and its various properties are comparable to those of human cranial bone, which can be complexly shaped, with excellent mechanical properties and a smooth appearance, without causing cutting injuries or affecting various post-operative medical examinations. It has been used for cranial bone repair for countless patients since its development. At present, the application of this new material has been unanimously recognized and highly evaluated by patients and medical experts.
