At what age can a skull defect be repaired? Cranial repair is a common neurosurgical procedure to repair the skull in response to a traumatic brain injury resulting in a skull defect. Patients with cranial defects often have a heavy burden of thought such as insecurity, and can cause headaches, dizziness, fear of vibration and other syndromes. The longer the cranial defect, the higher the incidence of cranial defect syndrome and secondary brain damage. In order to restore the airtightness of the cranial cavity, keep the physiological intracranial pressure stable, and reduce the cranial defect syndrome. Cranial bone repair should be performed for cranial defects with a diameter of more than 3 centimeters, without muscle coverage and without contraindications. How old can I be to repair a cranial defect? Nowadays, the artificial material used in major hospitals for cranial bone repair is titanium mesh, which is relatively inexpensive, while a few hospitals have used PEEK material, which is superior to titanium mesh, for cranial bone repair surgery.PEEK material is an aromatic semipolymer, with low density, insensitive to temperature, and high tissue stability, which enables it to be sterilized at high temperature or under radiation without deformation. It is radiopaque and has no effect on CT and MRI results. In addition, the material is capable of being 3D printed or CAD/CAM’d to create cosmetically pleasing placements. What is the age at which the skull can be repaired with cranial repair surgery? Generally speaking, if there is a cranial defect after the age of 3, it is possible to perform cranial repair. After the age of 3, cranial growth is relatively slow, and clinical practice has found that the surgical risk of cranial repair is positively correlated with cranial growth during different periods of growth and development, so it is important to consider that cranial defect repair in children should be performed after the age of 3. In addition, within 3 months after the injury, it is the fastest period of neurological recovery, and the earliest possible restoration of cranial cavity integrity can The early restoration of the integrity of the cranial cavity can improve the development of brain tissue and promote the recovery of neurological function.
