The skull, a solid bone in the human head, plays an important role in human life, not only to ensure the integrity of the skull at all times, but also to maintain normal intracranial pressure and a stable intracranial environment. However, in reality, there are always many unforeseen accidents, resulting in many people with skull defects. The neurosurgical guidelines clearly state that cranial defects of 3cm*3cm or more should be repaired as soon as possible when the patient’s condition is stabilized. Although cranial bone repair surgery in most general hospitals can be carried out, but because the operation involves the human scalp, blood vessels, brain tissue, nerves and other important organs, but also found that there are patients with postoperative rejection of infection and other complications, so the patient should not be taken lightly, we must choose the advanced and mature cranial bone repair technology. It is reported that the polyether ether ketone peek cranial bone repair plastic surgery, with new high science molecular peek do implant material, take embedded repair mode, smooth articulation after surgery, strong resistance to hit, low rate of rejection infection. At the same time, we carry out personalized optimal design of the material and innovation and upgrading of surgical technology, introduce the concept of cosmetic plastic surgery, and formulate personalized cranial bone repair and cosmetic surgery plan for each patient, to ensure precise postoperative repair, symmetry of both sides of the appearance of the natural and beautiful. How much is peek material for skull repair? In fact, the specific cost of the surgery also needs to be based on the size of the patient’s defect area, the difficulty of the surgery, the presence of other comorbidities, the specific treatment care and other factors to consider.
