Cranial bone is responsible for the protection of intracranial tissues, once a cranial defect occurs, the impact is great, so cranial bone repair surgery is necessary. Currently, neurosurgery advocates early or ultra-early cranial repair, and generally speaking, 3 months after the defect is the ideal time for surgery. And before doing cranial repair surgery, it is important to make sure that there are no other abnormalities occurring in the patient’s skull. At present, many hospitals can do skull repair surgery, but the key is whether the surgical materials are safe or not and whether the results are good or not. For example, some hospitals are now using titanium mesh material for skull repair. Titanium mesh material is indeed progressive compared to the traditional material of earlier times, but there are inevitably some problems, such as infection or rejection, collapse and deformation, exposed material, etc., so we do not advocate using it anymore. To achieve better skull repair surgery results, a safer and advanced repair material is needed, and the new polyetheretherketone peek material is very good. peek material’s properties are very compatible with the autologous skull, and well avoid the defects of various traditional materials, and the postoperative recovery is ideal. Of course, nowadays, not all hospitals can use peek material for surgery, and patients need to carefully choose experienced and skilled hospital doctors to do it. Our team has successfully performed surgery for many patients using peek materials, and the team has continued to improve and upgrade the technology and optimize the design of the materials, and also introduced the concept of aesthetic plastic surgery in the surgery, the results are highly affirmed and the appearance is more beautiful, achieving the organic unity of anatomical integrity, functional perfection and beautiful appearance.
