Cranioplasty is a surgical procedure to remedy cranial defects due to various reasons. The main objectives of the procedure are: on one hand, to repair the defective bone window using repair material implantation to regain the integrity of the skull and the closed environment of the cranial cavity; on the other hand, to reestablish the patient’s self-confidence by repairing the appearance of the defect. With the increasing number of cranial defects due to traffic accidents and natural disasters, cranial repair surgery is being performed more and more widely in the field of neurosurgery. Although skull repair is a routine procedure in the field of neurosurgery, postoperative complications due to the traditional surgical approach (titanium mesh skull repair) are numerous, and the traditional titanium mesh skull repair needs to be further upgraded and improved. Although the price of traditional titanium mesh cranial repair is relatively low, the implant material is metal titanium and the overlay repair is used, which leads to high rate of postoperative rejection infection, high risk of titanium mesh exposure and other disadvantages. At present, a mature cranial bone technology – peek material cranial bone repair plastic surgery has emerged, it uses the new polymer material polyether ether ketone peek as the cranial bone repair implant material, effectively reducing the chance of postoperative infection and rejection; at the same time, the embedded repair method, effectively avoiding the traditional titanium mesh cover repair caused by skin wear ulceration, the material exposed and other phenomena; in addition, the other way of repair, effectively avoiding the traditional titanium mesh cover repair, In addition, the innovative introduction of plastic concept, combined with the unique mesh aperture design and unique tissue separation and reset technology, effectively avoid temporal muscle atrophy, to ensure the activity of the tissues, to ensure postoperative symmetry, to achieve a natural and beautiful appearance. It is reported that PEEK cranioplasty has performed good repair for hundreds of patients, with good postoperative results and low chance of adverse sequelae, which is widely praised by patients and many experts in the medical field. In addition, there is no exact amount for the price of skull repair. The cost of skull repair depends on the size of the patient’s skull defect and varies greatly among individuals.
