After millennia of development, current repair techniques have been perfected, with low surgical risk and high efficiency. Patients do not have to worry about the potential environmental threat to the brain tissue inside the skull if the skull is not repaired properly. The key to cranial bone repair surgery lies in the selection of a better cranial bone repair material. At present, the more widely used clinical material is titanium mesh, this material there are some less than ideal situation, can not be complex shaping; caused by metal cutting pain; titanium alloy insulation is not very good, easy to cause the patient’s postoperative reaction to the hot and cold sensitivity; titanium alloy tissue integration is not perfect, some patients may have a rejection; titanium alloy metal material, it may affect the patient to accept the postoperative CT, MRI and other medical examinations. CT, MRI and other medical examinations and other problems, which seriously limit the quality of life of patients in the future. The cost of cranial bone repair depends more on the cost of surgical materials to choose the cranial bone repair material used PEEK material, is the current medical field of emerging polymer materials, so, choose the regular material can rest assured that the surgery. PEEK material, is the current medical field of emerging polymer materials, has good mechanical properties, plasticity, chemical stability and biocompatibility, and can withstand high temperature, steam and irradiation disinfection, and can also be used to protect the patient’s health. Steam and irradiation sterilization, and radioactivity permeability and magnetic resonance scanning does not produce artifacts, less dense, lighter weight implants are more comfortable and do not conduct heat. Little to no life-threatening rejection or adverse symptoms have been noted after surgery. There are patients who have undergone the surgery for 5 years and are still in good health without any complications. Warm tips: PEEK is a new type of cranial bone repair material, allowing cranial bone repair to move into a new field of development and application. Therefore, patients and friends can rest assured that the treatment. It is recommended that patients go to regular hospitals as soon as possible to take appropriate repair materials, repair as soon as possible, and recover as soon as possible.
