Cranial repair is a level II procedure in the branch of neurosurgery and is considered major surgery, although not very difficult. The operation of cranial bone repair is limited to the epidural area and does not touch the brain tissue, but there is a risk of intracranial hematoma as well as damage to blood vessels, nerves, and muscles. Since the materials used for cranial bone repair are different from human tissue, there may be a risk of rejection. Poor care that results in infection of the surgical incision can cause the incision to remain open for an extended period of time and, in severe cases, can lead to intracranial infection. For patients and their families, cranial repair is done in the head, which will cause psychological pressure on patients and their families. However, cranial bone repair is now a very mature technology, and the missing skull is not only a safety risk, but also affects the aesthetics. Therefore, it is recommended that the patient should undergo cranial bone repair as soon as possible when the original disease has recovered well, and consult a professional physician for specific advice.
