Cranial repair is nowadays a routine brain surgery procedure performed on skull defects. Whenever surgery is mentioned, patients inevitably associate it with the issue of money. After all, when it comes to brain surgery, “it’s going to cost a lot”. The patient’s concern is not unreasonable. Considering the special nature of skull repair surgery, the size of the bone window to be repaired is different for each person, the qualification and level of the doctors in the hospital, and the choice of skull repair materials, the final cost of the surgery is definitely high and low. There is no single standard for the cost of cranioplasty, and a big factor is the choice of material. Patients who choose the traditional titanium mesh material will have a lower overall cost for a single surgery. However, a large number of clinical cases prove that titanium mesh is not the best material for cranial bone repair. Although it is inexpensive, the metallic nature of titanium mesh itself determines the possibility of multiple complications after surgery. Most patients will have a second surgery and spend money twice. PEEK is currently a very good material for cranial bone repair. It has a good fit to the bone window, no hot or cold reaction to the titanium mesh material, high strength of the bone plate, and can adhere well to the bone window, keeping the intracranial brain tissue unaffected. For adolescents in the growth and development stage, it can be well adapted to the growth and development of the skull without worrying about the mismatch between the skull growth and the restoration material.
