The presence of the skull helps the body to resist external damage and protects the intracranial tissues. However, we should know that the skull is hard but not indestructible, and there are many accidents in life that we cannot predict, and many people have suffered from skull damage due to accidents. When a skull defect occurs, it is important to go to the hospital for skull repair surgery as soon as possible. However, there are always some patients who think that their skull defect is not large and they should be fine without skull repair surgery. In fact, the consequences of doing or not doing cranial bone repair surgery are very obvious, the more obvious is to affect the appearance of the brain, some patients will slowly collapse the skull part, time will also appear dizziness symptoms, the whole person’s mental state is not very good, if accidentally bumped, more dangerous. Moreover, if the cranial defect is not repaired, it will seriously disrupt the normal work of intracranial tissues and affect the cerebrospinal fluid circulation and blood circulation in the patient’s skull, which will lead to a series of cranial defect syndrome and even directly endanger the life and health. From all these, it can be seen that cranial defects have a great impact and it is imperative to do cranial repair surgery. Of course, there is a better time for cranial repair surgery, generally patients with cranial defects larger than 3cm can complete cranial repair after 3 months, the earlier the repair, the better the recovery. Our team uses a more advanced skull repair material, namely peek material. This material is more ideal than traditional materials, and its properties are comparable to those of autologous cranial bone, so there is no need to worry about rejection after surgery, and the shaping effect is very good. Moreover, we constantly carry out technical improvement and upgrade, material optimization design, unique technology to increase blood flow, maintain tissue activity, prevent temporal muscle atrophy, and introduce the concept of aesthetic plastic surgery, so as to carry out comprehensive PEEK cranial bone repair and plastic surgery, to ensure the aesthetic appearance of the shape, widely praised.
