Cranial Repair Surgery Polyetheretherketone Cranial Repair, the brain is the command of the human body, dominating the body’s various life activities. Of course, the normal function of the brain can not be separated from the peripheral support, such as the support and protection of the brain cranium, to prevent external aggression, to provide a safe, closed, stable intracranial operating environment. In reality, however, there are a variety of risk factors that may cause damage to the skull, such as car accidents, such as traffic accidents, such as brain surgery due to craniocerebral disease and so on, may result in cranial defects. This will expose the brain to external dangers, destabilize the stable intracranial environment, cause obstacles to blood circulation and cerebral cremaster fluid circulation, and affect the operation of various neurological functions, which is very harmful to the organism and sometimes even fatal. Therefore, once a cranial defect occurs, it is necessary to carry out cranial bone repair surgery in a timely manner. In cranial bone repair surgery, the choice of repair material is quite important. Clinically, there is no lack of examples of improper selection of cranial bone repair materials, resulting in the failure of repair surgery or postoperative adverse reactions. For example, the commonly used titanium mesh material is not ideal. Postoperative rejection may occur, postoperative infection may occur, scalp tissue destruction, titanium mesh exposed, and have to remove the titanium mesh, then this repair is also a failure. In addition, titanium mesh also has bad insulation, not easy to shape, interference with nuclear magnetic CT examination and other problems, so titanium mesh is not the first choice of cranial bone repair material. Currently, there is a more excellent cranial bone repair material, called polyether ether ketone, also known as PEEK material. This polyether ether ketone cranial bone repair can effectively avoid the above problems, and achieve very ideal repair effect.
