Some people in life may have a defective skull due to cranial trauma or surgery and will need cranial repair surgery. When to perform the repair is more important, too early is not good, and problems may occur if it is late. So when is the best time for cranial repair? Generally speaking, after symptomatic treatment of a traumatic or surgical skull defect, it usually takes about three to six months to recover before cranial repair is performed. However, there are some contraindications to cranial repair surgery, such as intracranial infection, hydrocephalus, brain swelling, with these conditions, even after three months can not be operated on, the need to delay cranial repair, delayed cranial repair can be prevented from autologous or allogeneic implantation of infection. Of course, in addition to timing, the repair material is also very critical. Currently, the new polyether ether ketone (PEEK) material is used in clinical practice. This humanoid bone material is a near-perfect cranial bone replacement material due to its excellent properties. Its elasticity, heat insulation, hardness, stability and other properties are similar to the human skull, and can be fused with the human skull, and this material is a three-dimensional reconstruction, can be accurately matched to the defective area of the skull, to achieve good repair results. The above is the detailed introduction of the best time for cranial bone repair, I hope to help you, we recommend that patients go to the regular hospital as soon as possible to take a good cranial bone repair materials, repair as soon as possible can be restored to health as soon as possible.
