It is very important for patients with cranial defects to choose a hospital and materials for their cranial repair surgery. Good materials can achieve better recovery results. The titanium plate materials on the market are a little more advanced than those in the past, but they also have many defects. Specifically summarized as follows: 1, some patients may have different degrees of postoperative infection, there will be a lot of physical discomfort. 2, titanium plate material is a metal material, because of the strong thermal conductivity of metal, postoperative patients are prone to external sensitivity to hot and cold environments. 3, because the titanium plate material in the operation is used to cover the repair method, the edge of the material will cause cutting damage to the scalp, the patient may have some pain, and even scalp abrasion as well as the material exposed and so on. 4, there is another important point, the titanium plate material will interfere with the transmission of radiation, after the operation to do ct examination and MRI examination will be affected. It can be seen that the titanium plate material repair effect is not good, there are many sequelae, want to achieve better surgical results, it is recommended to use the new peek material. peek material is very good to avoid the various defects of the titanium plate material, excellent performance, the recovery effect is ideal. At present, our team is using peek material for surgery, and the team is constantly improving and upgrading the technology and material optimization design, and the introduction of the concept of cosmetic plastic surgery, the postoperative effect is more beautiful.
