What are the effects of not having cranial repair surgery for cranial defects? In the usual life of risky situations, but accidents exist everywhere, the skull in the case of force majeure suffered from the outside world may also be damaged, cranial defects are also more common in neurosurgery is a kind of disease. For example, traffic accidents, production safety accidents, falling objects, fights, cranio-cerebral surgery, etc. may damage the skull and eventually cause skull defects. The skull is located at the top of the human skeletal system, above the spine, and consists of 23 bones of different shapes and sizes, which are delicately articulated together to form a complete and closed cranial cavity that protects and supports the brain and the organs of the head and face. Therefore, the importance of the skull to the human body is self-evident. Once a defect occurs, cranial repair surgery should be performed in a timely manner. However, some patients may still have a chance, so what are the effects of not doing skull repair surgery for cranial defects? If you don’t have a skull repair surgery in time, it will have a great impact on the beauty of the appearance, in addition to the lack of a part of the skull, the intracranial environment will change drastically, the intracranial pressure is unstable, the cerebrospinal fluid circulation in the cranium may be affected by the cerebral circulation of the cerebrospinal fluid circulation in the cranium may be impaired, and the operation of intracranial neurological function may be impaired, resulting in a series of cranial defect syndrome, which will affect the whole physical and mental health of the person. Another important point is the safety issue, if not repaired in time, if the head is injured again, the brain tissue may be directly injured, and in serious cases, it may even be directly life-threatening, which is very dangerous. Therefore, it is very necessary to have a skull repair surgery in time. When doing skull repair surgery, the repair material is very important, and the surgical technique is also very important. Currently, the new polyether ether ketone (peek material) is used for cranial bone repair. The peek material can achieve the ideal effect of cranial bone repair. This PEEK material, is a special polymer material, and human skull properties are comparable, has a high degree of biocompatibility, and can be three-dimensional shaping, highly restore the physiological structure of the skull, is the ideal cranial bone repair material.
