It is understood that more than 1.3 million people in China each year due to traffic accidents resulting in unintentional injuries, of which craniocerebral trauma accounted for 17%-23% of all traumas, the mortality rate of heavy craniocerebral injury is greater than 20%, and the rate of severe disability is greater than 50%. Behind such huge data, patients are especially concerned about the recovery of postoperative repair. When a defect occurs in the skull, a specific medical material is needed to repair the defective area. The development of cranial bone repair materials has gone through a long and tortuous process. The first repair materials were acrylic resin, polyethylene, and silicone rubber, which were eliminated due to serious defects, and then light apatite and calcium phosphate bone cement, which were withdrawn from the category of materials to be selected due to many complications. Currently widely used are titanium metal and polyether ether ketone. Titanium metal has been clinically used and found to have a high rate of postoperative rejection infection. Polyetheretherketone, as an advanced polymer material, has excellent performance and good results. Then many patients ask with polyether ether ketone for cranial bone repair material reduction is high? Polyetheretherketone peek cranial repair plastic surgery, through three-dimensional reconstruction, 3D printing, can highly restore the structure of the cranium, after the repair of both sides of the symmetry. Polyetheretherketone peek cranial bone repair plastic surgery has successfully broken the limitations of traditional repair, innovatively added the concept of plastic surgery, for each patient with cranial defects in the specific signs of the disease, the development of personalized and thorough cranial repair and appearance of the plastic program; in the details of the operation is also to enhance the best, such as in the design of the material aperture thickness design, design of the edge of the material, the separation of various layers of tissue reset protection, preventing Temporal muscle atrophy, prevention of scalp abrasion, cosmetic plastic surgery, etc. A lot of improvements have been made to complete the cranial bone repair while realizing the appearance of the overall natural and beautiful, greatly improving the overall effect, which is highly praised by the majority of patients with cranial bone defects.
