The skull is like a shield for the brain, it protects the brain tissue from the outside world, however, there are unpredictable events in the sky, sudden accidents can lead to skull defect, and the brain is in danger at this time, patients must pay attention to it and take active measures to remedy it. Because after the cranial defect, the closed cranial environment is destroyed, the intracranial pressure will be unstable, and the cerebrospinal fluid circulation and blood circulation are thus affected, which will have an impact on the operation of the whole body. In addition, if the cranial defect is not treated in time, once the secondary collision occurs, it will directly harm the intracranial tissues and affect the life safety. In clinical practice, the general conventional treatment for skull defect is to do skull repair surgery, which is a classic surgery in neurosurgery and can be done in general hospitals, but the surgical materials adopted by each hospital are different and the technical experience of the operator is different, which may lead to some differences in the results. Nowadays, most hospitals are using titanium mesh material, which may be said to have a lot of progress compared with the early materials, but there are also some unavoidable problems, such as postoperative infection, slightly greater chance of rejection, affecting postoperative medical examination, and even the risk of material exposure, etc. At present, the more advanced material for skull repair surgery is polyether ether ketone peek material, which makes up for the shortage of titanium mesh material, with suitable elasticity, high hardness, good heat insulation, strong stability, good histocompatibility and ideal postoperative effect, and has become the new trend of skull repair material. We have successfully used peek material to perform the surgery, and also combined with the concept of aesthetic plastic surgery, successfully carried out peek skull repair plastic surgery, the postoperative effect is still good. how much does PEEK skull repair plastic surgery all cost? This depends on the size of the defect area and the specific condition of the patient, different patients have different conditions, the cost of surgery will be different, regular medical institutions charge reasonable and fair, patients do not have to worry.
