Does cranial repair affect life expectancy? Defects in the skull are not uncommon in the population, and there are many people who have to undergo skull repair surgery due to cranial trauma, surgery, and other reasons that may lead to defects in the skull. Because cranial defects have a significant impact on the functioning of human life, the skull needs to be repaired in order to ensure healthy functioning of life. In fact, successful cranial repair surgery can be performed without affecting life expectancy when the skull is repaired intact. However, the effect of repair is also affected by the materials used for cranial bone repair. For example, the titanium mesh material widely used in clinic nowadays, although it is already a more advanced and mature material, and also much more advanced than other general materials used in the past, this titanium mesh material still has some drawbacks or complications and so on. The current clinical use of a new polyether ether ketone (PEEK material) can achieve the desired effect of cranial bone repair. This PEEK material, is a special polymer material, and the human skull performance is comparable, has a high degree of biocompatibility, and can be three-dimensional shaping, highly restore the physiological structure of the skull, is the ideal cranial bone repair material.
