Long-term craniosynostosis can be harmful to children in many ways, affecting their brain development, causing craniosynostosis syndrome in children, and increasing the risk of re-injury due to children’s hyperactivity. The child will also be resistant to things such as fear of sunlight, fear of vibration and even fear of loud noises. It also affects the child’s life, socialization and causes psychological disorders. Early cranial repair in children can protect their brain tissue in the defective area from re-injury, and at the same time create good conditions for further growth of new bone for an ideal cranium with normal physiological curvature. One to three months after injury is a rapid period of neurological recovery, and early restoration of the integrity of the cranial cavity is a prerequisite for further neurological recovery, which both improves the hemodynamics of local brain tissue and relieves the compression of brain tissue in the defect area by atmospheric pressure. It has variously facilitated the recovery of limb paralysis, aphasia, and mental or intellectual impairment associated with the injury site that occurs later in some children with craniocerebral injury. Attention must also be paid to the materials used for cranial repair in children. Good repair materials need to be selected, as general materials can cause many sequelae and discomforts. PEEK has become the new trend in skull repair. Warm tip: The above is the detailed introduction of “long-term cranial defect will bring what kind of harm to children”, I hope it will help you. It is recommended that patients with cranial defects go to regular hospitals to take appropriate materials to repair the skull as soon as possible, so that they can recover as soon as possible.
