Cranial defects are relatively common in current society and are frequently encountered in neurosurgical practice. After the occurrence of cranial defects, it is generally recommended that cranial repair is needed as soon as possible. Many patients will ask, what are the consequences of doing or not doing cranial repair? In fact, cranial defects cause serious harm to the body, if you do not do cranial repair as soon as possible, then there are not only aesthetic and safety issues, but also may affect the intracranial cerebrospinal fluid circulation, blood circulation, etc., affecting the normal operation of the brain and nerve function, resulting in a series of cranial defect syndrome, a serious danger to life and health. At the same time, it is also a kind of trauma to the patient’s psychology, and the patient often has some psychological disorders, low self-esteem, depression, sullenness, poor spirit and so on. So timely cranial bone repair is necessary. At the same time, it is very important to choose the material of cranial bone repair, the current medical application of new polyether ether ketone PEEK material. the main component of PEEK is hyaluronic acid and Ebenezer, biocompatibility is high, the phenomenon of postoperative complications and foreign body reaction, the clinic basically did not. Second, PEEK has a better modulus of elasticity, and the bone plate made by 3D technology printing can be perfectly three-dimensionally shaped according to the patient’s monitoring data before the operation, which perfectly restores the original structure of the skull. Third, the strength, insulation and stability of PEEK are similar to that of the autologous skull, and it will not affect the medical examination such as CT MRI in the future, and even if craniotomy is needed in the future, this material can be reused after sterilization. The use of an advanced polyether ether ketone PEEK material can rebuild a complete closed cranial cavity environment for the patient, which can help the recovery of the corresponding nerve function, and achieve the good effect of structural integrity, perfect function and beautiful appearance. Warm reminder: the above is the detailed introduction of the consequences of cranial bone repair surgery do or do not do it, I hope it will help you.
