There are always various dangers in life, for example, there are many people who suffer serious cranial trauma due to sudden traffic accidents, production accidents, etc., resulting in cranial defects. Cranial trauma requires timely treatment, and the cranial defect should also be repaired in time, as failure to do so can cause many hazards and lead to a series of cranial defect syndrome, and sometimes even life-threatening. After skull defect, it will lead to the instability of intracranial pressure, which will interfere with the circulation of cerebral crest fluid and the operation of intracranial life activities, causing some neurological dysfunction, symptoms may include dizziness, headache, unfavorable language, abnormal facial expression, depression and irritability, low self-esteem and so on. Therefore, patients should undergo skull repair in time. In fact, it is quite convenient to seek medical treatment nowadays, so you can first make some online consultation for cranial bone repair to know the better hospitals to do it. Through online consultation and search, we can learn that the effect of cranial bone repair surgery is very closely related to the material used for cranial bone repair. Good materials can achieve better post-operative results, while bad materials may lead to various post-operative problems. For example, the titanium mesh material commonly used in clinical practice still has some disadvantages, such as rejection, infection, cold and heat inconvenience, and interference with medical examinations such as CT and MRI, so it is better not to use titanium mesh material. At present, there is an emerging polyetheretherketone PEEK material, more excellent performance, postoperative results are also better. Polyetheretherketone is a special polymer material that is gradually becoming the latest trend in cranial repair materials due to the material’s good biocompatibility, ability to be complexly shaped, excellent mechanical properties, good protective properties, and high postoperative comfort.
