People are actually like a machine, any missing parts of the body, that will have a certain impact on the operation of the entire body. For example, the skull, which is a very important group of bones in the human skeleton, it is hard and elastic, is a layer of protective barrier for the brain, but the occurrence of accidents lead to damage to the skull, then the whole body will be implicated. The intracranial pressure and intracranial environment of patients with skull defects will change accordingly, and blood circulation in the brain and cerebrospinal fluid circulation will be impaired, so the intracranial tissues can not work normally, and a series of uncomfortable symptoms will occur in the patient’s body. It can be seen that the danger of cranial defects is very great, once it happens, it is generally recommended to go to the hospital in time to do cranial bone repair surgery. Do cranial repair surgery, patients are more worried about the risk of the problem, but in fact this is a more classic surgery in neurosurgery, the technology has been very mature, safety is relatively high, want to achieve good cranial repair results, the focus is on the choice of good repair materials. What are the new cranial repair plastic materials? From the past to the present, cranial bone repair surgery has been developing and progressing, and the repair material has also had a constant iteration, the early bone cement, plexiglass, etc., and now there are titanium mesh materials and polyether ether ketone PEEK materials and so on. After a large number of clinical results show that the polyether ether ketone PEEK material is the ideal material for cranial bone repair surgery, which is a new type of polymer material, all the properties are excellent. At present, PEEK material is widely used in clinical cranial bone repair surgery, and also integrates the concept of cosmetic plastic surgery, not only can highly restore the physiological anatomy of the skull, the postoperative appearance is more natural and beautiful.
