In neurosurgery, we often encounter patients with skull defects due to accidents, and it is precisely because the occurrence of skull defects has a great impact on their lives and health, only active medical treatment can minimize the damage. After all, the skull is a very important group of bones in the human body, it plays a role in protecting the brain tissue, once the skull defects should not be careless. If the skull defect is not solved for a long time, the shape of the defective area of the skull will change, the scalp is affected by atmospheric pressure, but also to make it fall into the brain tissue, the patient will be very insecure, and there will be headaches, dizziness and other phenomena, and the longer the cranial defect, the greater the harm will be, and even life-threatening. Therefore, in order to restore the closure of the cranial cavity as soon as possible, in order to maintain the normal functioning of intracranial tissues, and also in order to reduce the occurrence of craniosynostosis, it is recommended that the patient should go to the hospital in time to do cranial bone repair surgery. What are the prices and materials used for cranial repair? Many patients are concerned about this question before having the surgery, but in fact, the price of cranial repair surgery can not be generalized, this will be affected by many factors, such as the severity of the patient’s defects, the patient’s choice of hospitals and materials and so on. Especially the choice of materials for skull repair, which will not only affect the cost of the surgery, but also affect the effect of the surgery. At present, the better cranial bone repair material is PEEK material, which is a new type of polymer material, its performance is very excellent, it successfully make up for the shortcomings of the traditional materials, the postoperative recovery is very good, and has received widespread attention.
