The skull is a very important tissue in the human body, which plays a very important role in protecting and supporting the brain and the head and facial organs, maintaining the health of the human body and the life of the whole organism. Therefore, if a cranial defect occurs, it will bring great harm and requires timely cranial repair surgery. Some patients ask how traumatic skull defect repair can help in brain recovery. Traumatic cranial defects are mostly seen in accidental cranial trauma, such as car accident injuries, production safety accident injuries, accidental falls, falling object attacks, fights and so on. In these cases, more serious cranial trauma often occurs, and not only the skull may be damaged, but also the intracranial brain tissue may suffer, producing a series of cranial defect syndromes. Therefore, cranial repair surgery should be performed in a timely manner after the acute treatment of the skull defect left behind. This traumatic cranial defect repair is very helpful for brain recovery. It can not only repair the skull defect, restore the patient’s cranial appearance and protect the function, but also effectively restore the normal cerebrospinal fluid dynamics and cortical blood perfusion, which is helpful to reduce intracranial complications and help the patient’s neurological function recovery. At present, the more advanced and ideal cranial repair material is polyetheretherketone peek material, which is a new type of special polymer material, and its various properties are very close to human autologous cranial bone, which can achieve a more ideal repair effect. We widely use this advanced material, and constantly carry out technical improvement and innovation, material optimization design, and introduce the concept of aesthetic plastic surgery, so as to carry out comprehensive peek skull repair plastic surgery, can achieve excellent repair effect, widely praised and recognized.
