Does it matter if a piece of the skull is missing? Of course, the skull has an important supportive and protective role for the brain, and when a skull defect occurs, the intracranial tissues of the skull and the intracranial environment will be affected. At present, there are not only many adults with skull defects, but also some children with skull defects, which is worth paying attention to. Many people may think that children are still in the stage of growth and development, so even if they have a missing piece of skull, it is not a big deal, because they think that children’s skull will grow back on its own. However, the actual situation is not so optimistic. A few children with small skull defects may grow and heal on their own, but a large proportion of them will not grow on their own. Therefore, parents should not delay their children because of their own negligence, even if the child is in the growth period, the defective skull is still very difficult to grow well, only as soon as possible to do cranial repair surgery in order to prevent the child from suffering more damage. Will children grow back after skull repair? Cranial repair surgery is the most direct way to solve the problem of skull defects, so as to rebuild the closed cranial cavity and remodel the stable intracranial environment, which is of great significance to the operation of the whole life. However, there is a point where the selection of better performing materials for cranial repair surgery is important, and also relies on the high level of skill of the operator. The PEEK material currently used by our team has received a great deal of attention. Moreover, the team has carried out in-depth research to improve and update the technique, and has also successfully combined the concept of cosmetic plastic surgery to achieve a more desirable repair effect, which is a major innovation in the field of medicine, and has received unanimous favorable comments from patients and their families.
