The human brain tissue can function properly without the support of some other tissues, such as the skull. The skull can be said to be a piece of hard protective shell of the brain tissue, the cranium of the protection of the brain at all times, to provide a more secure and stable operating environment. However, when the skull is damaged in some accidents, the brain tissue loses the protection of the shell and is easily attacked. Hazards of cranial defects Cranial defects are of great importance, if not repaired in time, the brain may be susceptible to external aggression at any time; in addition, it will also seriously damage the stability of the intracranial environment, resulting in blood circulation disorders and cerebrospinal fluid circulatory disorders, triggering a series of neurological dysfunction, and in more serious cases, it may also be life-threatening. Therefore, every patient with cranial defects should recognize the stakes and seize the opportunity to go to a regular hospital for cranial bone repair surgery. Titanium plate material is commonly used, but there are still shortcomings Of course, the skull repair surgery must also pay attention to the choice of repair materials, good materials to help achieve a better repair effect. At present, many local hospitals tend to use titanium plate material, which is an improvement over the traditional material. However, titanium plate material also has some unavoidable shortcomings, such as postoperative infection, patients may have rejection reaction; titanium plate material is not very good at insulating, postoperative patients will be more sensitive to the external hot and cold environments; titanium plate material is a kind of metal material, which will affect the results of the postoperative MRI examination, and so on. What are the chances of titanium plate exposure for cranial repair after skull defect? This is one of the major drawbacks of using titanium plate material for skull repair, because titanium plate material is a covering type of repair, the edge of the material may cause cutting damage to the scalp tissues, and there is a high chance of exposure after a long time. Therefore, it is still recommended not to use titanium plate material for cranial bone repair surgery. Once the exposure occurs, you still have to carry out secondary repair, which is very troublesome.
