The skull is a very hard group of bones, which plays a great role in human life, and it is like a safety cap to protect the brain tissue at all times. However, even if the skull is hard, it can be injured once it is subjected to a major impact by external forces. The original closed cranial cavity environment will be destroyed after skull defect, and the patient’s intracranial pressure will become very unstable, which will also lead to skull defect syndrome, for example, the patient will have headache and dizziness, and the patient will become irritable and restless, and the patient himself will be especially insecure, which is even more dangerous if he is not careful to receive secondary trauma. It can be seen that cranial defects really cannot be ignored, especially if the defect area is large, it is necessary to go to the hospital for cranial repair surgery in time. What material is good for skull repair and how much does it cost? This is a question that patients are concerned about, but the cost of skull repair surgery cannot be generalized, each patient’s situation is different, the repair materials used are different, the overall cost is naturally different. As for the skull repair material, there are still many repair materials used in the development of skull repair surgery until now, and there are also constant changes, the material is getting more and more advanced and the technology is getting better. At present, the skull repair surgery effect is better is the new polyether ether ketone peek material, which is a very safe polymer material, its performance is very good, the price is also proportional to the effect. At present, we are using peek material to carry out surgery for the majority of patients, and after efforts, we also carried out technical upgrades and material optimization design, successfully introduced the concept of aesthetic plastic surgery, making the post-operative effect more natural-looking, and has been unanimously praised by patients and families.
