The skull is a protective wall for the brain tissue, which protects the intracranial tissue from external aggression. Nowadays, all kinds of unexpected accidents, together with some mechanical injuries and so on, have increased the probability of skull defects occurring. Cranial defects are more dangerous than we think, and it is important to pay attention to them and undergo a cranial repair surgery before it is too late, in order to rebuild the external defense wall of the brain tissue. Cranial bone repair surgery is very common in neurosurgery, it is an old and classic surgery, which has undergone a long history of development, especially in the use of repair materials have also had a constant iteration, from the beginning of the bone cement, plexiglass to the current titanium alloy, are all signs of progress. How about titanium alloy for skull repair? Titanium alloy is a material used in many hospitals nowadays, which is inexpensive and progressive. However, titanium alloy is a metal material that is implanted, and there are some defects and shortcomings in clinical use. For example, postoperative infection and rejection may occur, it will wear down the scalp, it will collapse and deform when subjected to external forces, and there is a risk of material exposure. In fact, now in addition to titanium alloy material, there is a more ideal material, that is, polyether ether ketone PEEK material, PEEK material performance is better than titanium alloy, this is a kind of advanced polymer material, tissue compatibility is very good, basically will not occur in rejection reaction, PEEK material also has three-dimensional molding function, can be better restored to the physiological structure of the skull. In addition, PEEK is an embedded repair material, so the appearance of the skull is smooth after surgery, unlike titanium alloy, which can cause cutting damage. Currently, our team has pioneered the use of PEEK material for surgery. Our team of experts is experienced and skilled, and we are constantly improving and upgrading our technology and optimizing the design of our materials, as well as introducing the concept of cosmetic plastic surgery to carry out comprehensive PEEK cranioplasty, which provides a more beautiful postoperative result.
