The skull is a very important bone tissue in the human body, which protects the brain tissue inside the skull from external damage and maintains normal intracranial pressure and stable intracranial environment, which is also an important guarantee for the normal functioning of brain nerves. However, there are many dangerous factors in life that may threaten the skull, such as traffic accidents, production safety accidents, falling objects, fights, cranial surgery, etc., all of which may cause skull defects. Once the cranial defect occurs, the soft tissues inside the skull will be easily damaged by the external direct injury due to the lack of hard shell protection; and the changes of intracranial pressure and intracranial environment caused by the cranial defect will also trigger a series of neurological abnormalities and cause some cranial defect syndrome, which is very harmful and may even be fatal in serious cases. Therefore, once cranial defect occurs, cranial bone repair should be performed in time to restore the protection of brain tissue and restore the closed and stable intracranial environment. In fact, cranial repair surgery is a relatively routine surgery in neurosurgery, the technology is more mature, and the cost of treatment actually has a great relationship with the cranial repair materials selected. For example, some hospitals use titanium mesh material, the cost may be slightly lower, but it is not effective, may cause many is not symptoms, is by the rejection of infection occurs, will also affect the CT nuclear magnetic examination and so on. The new polyether ether ketone PEEK material, however, can well avoid the above problems and achieve ideal repair results, and the cost is not particularly high. PEEK material is a special polymer material that is gradually becoming a new trend in cranial repair materials because of its good biocompatibility, ability to complex shaping, excellent mechanical properties, good protective properties, and high postoperative comfort. Civil Aviation General Hospital neurosurgery is the use of PEEK material to do cranial bone repair surgery, to achieve good clinical results, recognized and praised by patients. Warm tip: The above is a detailed introduction of polyether ether ketone PEEK material cranial bone repair, I hope it will be helpful to everyone. It is recommended that patients with cranial defects go to regular hospitals to take appropriate materials to repair the skull as soon as possible, and recover early.
