The key to skull repair surgery is the need to choose a better skull repair material. At present, the more widely used material in the clinic is titanium mesh, this material on the existence of some less than ideal situation, can not be complex shaping; cause metal cutting pain; titanium alloy is not very good thermal insulation, easy to cause patients sensitive to hot and cold reaction after surgery; titanium alloy tissue compatibility is also not too perfect, some patients may appear rejection; titanium alloy this metal material, may affect, patients receive postoperative CT, MRI and other medical examinations, which seriously restrict the quality of life of patients in the future. The PEEK material used for cranial repair is an emerging polymer material in the current medical field, with good mechanical properties, easy plasticity, chemical stability and biocompatibility, can withstand high temperature steam and irradiation sterilization, and radioactive permeability and magnetic resonance scanning will not produce artifacts, less dense, lighter weight implants are more comfortable and do not conduct heat. Little to no postoperative vital rejection or adverse symptoms have been noted. Patients who have undergone the procedure at our facility for five years are in good health with no complications to date. Experts say that PEEK is the emerging material for cranial bone repair, allowing cranial bone repair to move into a new area of development and application. So patients are assured of treatment. The price of cranial bone repair cannot be generalized. It includes the cost of hospitalization, surgery, anesthesia, care, medication, etc., like polyether ether ketone PEEK material, although the cost will be relatively high, but its performance is excellent, the repair effect is very good, is completely worth it.
