Each part of the human body has its own role, but any problem with any part will have an impact on the health of the body in one way or another. The skull is a very important part of the human skeletal tissue, and it is like a protective barrier for the brain. The skull is intact so that the tissues inside the skull can function properly. But accidents can lead to cranial defects, which have to be taken seriously. There is no doubt that the skull shape will become unattractive after skull defect, and besides this, the impact of skull defect on health is also relatively large, skull defect destroys the stability of the intracranial environment, cerebrospinal fluid and blood circulation problems, and will damage the neurological function, causing a series of skull defect syndrome, etc. If a secondary impact occurs, the consequences are even more unimaginable. Cranial defects are dangerous and patients need to go to the hospital for cranial repair surgery to restore the integrity of the skull and reshape the stable cranial environment as soon as possible. In which department is cranial defect repair done? Cranial repair surgery is a classical surgery in neurosurgery, and it is usually a neurosurgery department when you go to the hospital for cranial defect, and it is not a major surgery, but the choice of surgical material cannot be sloppy, and the technical experience of the surgeon is also very important. At present, titanium mesh material is widely used in many places, which is much more advanced than various materials in the early days, but there are still certain defects and shortcomings, and there are always inevitable problems after surgery, and there are even cases of material exposure.
