Cranial repair is a relatively routine procedure in neurosurgery and the technique is well established. It is a surgical procedure to repair cranial defects caused by various reasons, which can restore the complete shape of the skull and restore the safe and stable environment in the skull. It is essential to perform skull repair in time after skull defect. Because if not repaired, it may cause great harm to the organism, and may even be life-threatening in serious cases. And the choice of repair material is very important in the cranial repair surgery. Good materials can achieve better repair results, while if the materials are not properly selected, it may cause some adverse reactions. For example, some local hospitals use titanium mesh material for skull repair, and sometimes there are uncomfortable symptoms. For example, titanium mesh is not insulated, so there will be headache and dizziness in hot and cold environment; titanium mesh overlay repair, the edge of the material may cause cutting injury to the scalp; titanium mesh, a metal material, may also affect the postoperative medical examination such as CT MRI; and the histocompatibility of titanium mesh is not very good, so rejection reaction or postoperative infection may occur, or even the scalp tissue may be destroyed, resulting in the exposure of titanium mesh. What about the exposed titanium mesh after skull repair? Do I need to change the peek cranial material? If the titanium mesh is exposed, it is recommended that the titanium mesh be surgically removed and the scalp be restored to heal before the skull is repaired. The PEEK material is an ideal material for cranial repair, and its properties are very close to the human skull, without the above-mentioned drawbacks of titanium mesh.
