When hearing the problem of cranial defects, people can’t help but feel worried, because the skull is like a protective wall for the brain, once the skull is defective, the protective wall collapses, then the operation of all intracranial life activities will be affected accordingly, so people have to be vigilant. And after the skull defect, the intracranial environment has changed, the impact on the patient’s brain function is also more obvious, the patient will also appear a series of skull defect syndrome, the original life and work will be affected. If the skull defect is not repaired for a long time, the defective part will be partially sunken, and the patient will feel insecure. Therefore, when a skull defect occurs, the patient should realize the seriousness of the problem and go to the hospital in time to have a skull repair surgery, so that the closed cranial cavity can be restored as soon as possible to avoid causing more harm to themselves. How much does cranial repair cost? Many patients will be concerned about the cost of surgery, but this is not certain, each patient’s situation is different, the specific should be combined with all aspects of the factors for a comprehensive assessment, so as to know the approximate cost. At the same time in the skull repair surgery, the choice of repair material is also very critical, which not only affects the cost, but also has a certain impact on the effect of surgery. At present, many hospitals are widely using titanium mesh material, which is much improved and cheaper than the earlier repair materials, but the titanium mesh material also still has some shortcomings and defects, and there will be some complications after the operation. Our team has adopted a new type of polyetheretherketone peek material, which breaks the drawbacks of titanium mesh material, and the properties of peek material are very compatible with the autologous skull, and the postoperative recovery effect is very ideal, which has become a new trend of cranial bone repair material. We also continue to improve and upgrade the technology and optimize the design of materials, and introduce the concept of cosmetic plastic surgery, comprehensively carry out PEEK cranial bone repair plastic surgery, with good clinical results.
