The key to cranial bone repair surgery lies in the need to choose a better cranial bone repair material. At present, the more widely used clinical material is titanium mesh, this material still exists some less than ideal situation, can not be complex shaping; caused by metal cutting pain; titanium alloy’s thermal insulation is not very good, easy to cause the patient’s postoperative reaction to cold and heat sensitivity; titanium alloy’s tissue compatibility is not too perfect, some patients may have a reaction to the rejection; titanium alloy metal material, it may affect the patient to accept the postoperative CT, MRI and other medical examinations and so on. CT, MRI and other medical examinations, etc., which seriously limits the quality of life of patients in the future. The PEEK material used in cranial bone repair surgery is an emerging polymer material in the current medical field, which has good mechanical properties, easy plasticity, chemical stability and biocompatibility, can withstand high temperature steam and irradiation disinfection, and radioactivity transmittance and magnetic resonance scanning will not produce artifacts, less dense, lighter weight implants are more comfortable, and will not conduct heat. Almost no vital rejection or adverse symptoms have been noted after surgery. Patients who have undergone the procedure with us for 5 years are still in good health without any discomfort. PEEK is an emerging material for cranial bone repair, allowing cranial bone repair to move into a new field of development and application. Therefore, patients and friends can rest assured that the treatment. The price of cranial bone repair cannot be generalized. It includes the cost of hospitalization, surgery, anesthesia, nursing care, medication, etc. Like polyether ether ketone PEEK material, although the cost will be relatively higher, but its performance is very excellent, the repair effect is very good, it is completely worth it. cranial defects, should be in the right time as soon as possible for cranial bone repair. Usually after the defect occurs, the recovery from emergency treatment is about three months, and cranial bone repair can be performed. Cranial bone repair is now a relatively routine procedure in neurosurgery, and technically there is basically not much of a problem, which lies mainly in the quality of the repair material. At present, the titanium mesh material used in most hospitals has some unsatisfactory problems, such as rejection reaction caused by titanium mesh exposure, such as a variety of discomforts, such as postoperative patients are sensitive to heat and cold, such as affecting the postoperative CT MRI and other examinations. At present, the clinical use of advanced polyether ether ketone PEEK material, this material is almost equivalent to the human skull because of its excellent performance and can achieve very good cranial bone repair effect, has become the new favorite of the cranial bone repair industry.
