If skull defect is not repaired, it will seriously disrupt the normal work of intracranial tissues, affect the cerebrospinal fluid circulation and blood circulation in the patient’s cranium, cause a series of skull defect syndrome, and even directly endanger the health of life. From all these, it can be seen that cranial defects have a great impact and it is imperative to do cranial repair surgery. The presence of cranial bone can help the body to resist external damage and protect the intracranial tissues. However, as we all know, the skull is hard but not indestructible, and there are many accidents in life that we cannot predict, and many people suffer 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 area is not large, so they should be fine without skull repair surgery. Skull defect must be repaired, some patients’ skull parts will slowly collapse, and the symptoms of dizziness will appear after a long time, and the whole person’s mental state will not be very good, and it will be more dangerous if accidentally bumped. 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 cranium, which will cause a series of cranial defect syndrome and even directly endanger the life and health of the patient. From all these, it can be seen that the impact of cranial defect is great, and it is imperative to do cranial bone repair surgery. Currently, a peek material is used in clinical practice. This material is more ideal than traditional materials, and its performance is comparable to that of autologous cranial bone, so there is no need to worry about the existence of rejection after surgery, and the shaping effect is very good. We continuously carry out technical improvement and upgrade and material optimization design, unique technology to increase blood flow, maintain tissue activity, prevent temporal muscle atrophy, and introduce the concept of cosmetic plastic surgery, thus comprehensive PEEK cranial repair plastic surgery, to ensure the cosmetic beauty of the shape, well received.
