The skull is hard and elastic and has the important duty of protecting the brain. However, under the influence of some irresistible force factors, the skull is damaged, which not only affects the appearance, but also the patient will face various health crises. Therefore, what should be done for cranial defects is to go to the hospital for repair in time to restore the integrity of the head as soon as possible, and return their beauty and health. In neurosurgery, skull repair surgery has a long history and is a very mature surgery, so patients don’t need to worry about it, but they need to go to a regular hospital and let experienced specialists to operate in order to achieve good results. And one thing is that the choice of repair material is also very important to ensure the ideal result of cranial bone repair. The traditional materials are bone cement, plexiglass, and nowadays, titanium mesh material is widely used in many hospitals. Titanium mesh material has improved a lot compared with those in the past, but it also has certain defects and shortcomings, there is a certain chance of infection and possible rejection after surgery, and there is also the possibility of material exposure and concavity. Can the depression be restored to flatness after skull repair? It is recommended to remove the titanium mesh and replace it with a better material in time. Currently, the best material for skull repair is polyether ether ketone PEEK, which is a new type of polymer material with stable properties and is comparable to autologous skull bone, and it is ideal for postoperative recovery without worrying about sequelae. However, PEEK is not yet widely used in China, and only a few hospitals have been able to use PEEK for treatment, and we are one of them. In addition to good repair materials, our team has continued to conduct in-depth research and exploration, and has carried out technical upgrades and innovations, successfully introducing the concept of cosmetic surgery for better repair results.
