The skull is an important protector of the human brain, which is very dangerous when there is extensive damage to the skull. Because the cranial tissues are not protected by the skull, they are completely exposed and can be attacked at any time. Moreover, if the skull is damaged, it will have a great impact on the overall appearance and image, and the patient will become very low self-esteem and pessimistic. Therefore, skull repair surgery is necessary for both health and image reasons, and patients should not be careless about it. Does skull repair affect life expectancy? This is the concern of many patients who are going to have skull repair surgery, in fact, there is no need to worry, the life expectancy of patients will not be affected after skull repair surgery, patients can live and work as normal people. However, the effectiveness of skull repair surgery is directly dependent on the repair material. At present, many hospitals use titanium mesh material, but titanium mesh material has great defects and can bring some complications after surgery. Therefore, the skull repair material is slowly being upgraded and improved, and nowadays, the more ideal repair effect is peek material. This is a polymer material, which has strong tissue compatibility, even with the human cranial bone properties, post-operative recovery would like to be quite good. Once the skull defect occurs, patients must go to a regular hospital for skull repair surgery as soon as possible, and must choose the real ideal skull repair material so as to achieve a better skull repair effect.
