We live in a complex social environment, where there are various dangers and accidents, and our skulls can be damaged in these dangers and accidents. For example, traffic accidents, production safety accidents, falling objects, fights, and craniotomies due to craniocerebral diseases, etc., all of these situations may eventually lead to cranial defects. If a skull defect is not treated in time and the skull is not repaired in time, there is a high risk of health problems. Patients with large-scale cranial defects may suffer from localized scalp subsidence due to atmospheric pressure, which may lead to imbalance of intracranial pressure, displacement of brain tissues, as well as reduction of cerebral hemispheric blood flow and cerebrospinal fluid circulation disorders, thus causing a series of clinical manifestations, mainly including: headache, vertigo, irritability, epilepsy, discomfort without any other explanations, and a variety of mental disorders. Of course, patients do not need to worry and fear too much, these can be prevented and improved by cranioplasty, also known as cranial bone repair surgery. The choice of material for cranial repair is very important. At present, the more advanced and ideal cranial bone repair material is polyetheretherketone peek material, which is a new type of special polymer material, its various properties are very close to the human autologous cranium, which can achieve a more ideal repair effect, at present, our team is still widely used in this advanced material, and continue to improve the technology innovation, material optimization design, and the introduction of the concept of cosmetic plastic surgery, so as to carry out the peek cranial bone repair surgery, so as to improve the quality of the skull. The peek cranioplasty has been widely praised and recognized for the excellent results it can achieve.
