Cranial defects are a common disorder. Sudden accidents, natural disasters, and various craniofacial surgeries are important causes of cranial defects. The loss of the skull as an important protective umbrella, the brain tissue is exposed to the outside world for a long time and is vulnerable to secondary damage. There is also extracranial atmospheric pressure that can act directly on the brain tissue, severely damaging the patient’s brain function. Patients may also suffer from memory loss, inattention, irritability, agitation, anxiety and other related psychological and physical symptoms. Therefore, cranial defects need to be repaired in a timely manner. Currently, peek skull repair surgery is more commonly used in neurosurgery, which is a high-grade peek implant material with good histocompatibility, less rejection and infection. The price of peek material occupies a larger proportion in the whole skull repair surgery, and the examination fee, hospitalization fee, medicine fee, nursing fee, anesthesia fee and surgery fee are also several factors that affect the price. As peek skull repair surgery is widely carried out in the clinic, patients are no longer satisfied with the restoration of normal skull appearance, and new demands are made on the operator, paying more attention to the overall unity of aesthetic appearance and scalp sensory comfort. In recent years, the concept of aesthetic plastic surgery has been innovatively incorporated into peek skull repair surgery, which greatly improves the postoperative aesthetic appearance. peek skull repair can, on the one hand, restore the physical integrity of the skull, stabilize the intracranial pressure, and greatly reduce the damage caused by external factors. On the other hand, the improvement of the overall postoperative aesthetics can effectively reduce the long-term mental stress and psychological pressure suffered by patients.
