There are many reasons for cranial defects in our lives, so patients with cranial defects should undergo cranioplasty as soon as possible. Because the brain tissue loses the shielding effect of the normal skull, it is easy to be injured twice, and at the same time, the skull defect can cause various symptoms and affect the appearance, therefore, many of these patients need to undergo cranioplasty, which is designed to make the patient’s intracranial pressure return to normal and stable as soon as possible, and to reduce the intracranial pressure due to the skull defects and the drastic changes, which can damage the brain function. It is generally believed that cranial bone repair should be performed more than 3 months after decompression surgery, and for infected patients, it should be prolonged to at least 6 months after decompression surgery. Because if the time is too long, the local skin scar is firm, and it is not easy to heal after the operation, and the skin is closely adhered to the meninges or brain tissues, which increases the difficulty of separation in the surgical operation, and it is more damaging to the skin and brain tissues. The skin flap collapse time is too long, easy to cause the skin flap shrinkage, suture after the skin edge tension easy to cause ischemic necrosis. PEEK (polyether ether ketone) is a special engineering plastics, PEEK materials, better tissue compatibility, strong resistance to pressure, perfect shaping, precise repair of the skull in the clinic is becoming more and more widely used, PEEK material is a bionic bone, can be highly compatible with the autologous cranial bone, and in the elasticity, heat conduction, hardness, stability and other aspects of the performance of autologous cranial bone is comparable to the performance of the autologous cranial bone, especially for children patients, he was able to Especially for pediatric patients, it can better adapt to the growth and development of autologous skull. It has become a better material for cranial bone repair. In many people’s opinion, cranial repair is a very scary surgery, but for neurosurgeons, it is a routine surgery with basically no risk, as long as you choose the right material for cranial repair, the possibility of postoperative infection or discomfort is very small. Currently, most hospitals use titanium mesh as a repair material, but after a while some patients experience varying degrees of discomfort, and although it is widely used, there are inevitable drawbacks. Everyone wants to repair the skull once and for all, and does not want to suffer the pain of rejection in the future, then the choice of polyether ether ketone material is the right choice at the moment. Polyetheretherketone material, also known as peek material, has achieved very good results, and patients have not had adverse reactions after surgery. If you use peek material to repair the skull, as long as there is a transfer certificate and related procedures, and in line with the health insurance reimbursement policy, can be reasonable reimbursement, the specific reimbursement rules and reimbursement costs should be based on the relevant local policies and the patient’s actual spending decision, the patient’s symptoms are different, the area of the defects are different, so the amount of money that will be spent on the surgery can not be generalized, the specific need for the patient to communicate with the doctor can be known. The exact amount of money to be spent on the surgery cannot be generalized, and can only be known after the patient has communicated with the doctor.
