Cranial repair has been a relatively routine and mature procedure in neurosurgery. With the development of medicine, there are various materials for cranial bone repair, and although the efficacy varies, they can basically meet the criteria for repair. Patients are generally concerned about the cost of surgery. The cost of a successful skull repair surgery is not only related to the hospital and doctor, but also the choice of materials. It can be said that the material cost of skull repair surgery accounts for a large part of the overall surgery cost. Generally speaking, the larger the damaged area of the bone window, the more materials are used, and naturally, the more it costs. Traditional titanium mesh materials range in price from$10,000 to tens of thousands of dollars, depending on the patient’s specific condition. Some patients cost more, some cost less. This is understandable compared to this. However, the major disadvantage of titanium mesh material is the post-operative rejection, and there are few cases of clinical complications such as fluid retention, inflammation and infection. Many patients who choose titanium mesh materials have to go to the hospital for a second surgery after complications arise, or take long-term medication to commemorate the control of their condition. In contrast, the advantages of PEEK are clear: PEEK has a high degree of bionic compatibility with autologous bone, in other words, the performance of PEEK is comparable to that of human bone, which does not cause all kinds of complications, but also promotes the growth and development of human bone, and is particularly effective for pediatric patients with cranial damage. the clinical results of PEEK materials are good, and naturally, they are relatively expensive. Patients who need cranial bone repair surgery can choose a reasonable repair material according to their own economic situation to avoid long-term cranial bone defects that can be very harmful to the body.
