Craniosynostosis is a relatively common disorder in neurosurgical clinics and can be relatively harmful, potentially causing a variety of dysfunctions and producing a range of craniosynostosis syndromes. For example, some patients may experience headaches, dizziness, irritability, seizures, discomfort with no other explanation, and various mental disorders. Other patients may experience symptoms such as vision loss and memory loss. So patients with cranial defects should undergo cranial repair in time? Some patients ask if cranial bone repair is effective in restoring vision? Let’s take a look at a case: 16-year-old Xiaohou suffered a car accident on the way to school, and his head was seriously injured, and he was sent to the local hospital for treatment. Emergency treatment was given to the cerebral contusion removal surgery and decompression of the bone flap, fortunately saved his life, but after the operation also left a large frontotemporal parieto-occipital cranial bone defects. The cranial defect not only made her head appearance very unattractive, her self-esteem was very hurt, she was depressed and even had low self-esteem, but also had some neurological dysfunction, vision loss, and her mouth and nose were a little crooked. Family members are very eager to do cranial repair surgery for Xiaohou as soon as possible. After a lot of understanding, they came to our clinic, we received after a detailed diagnosis and evaluation, the application of advanced polyether ether ketone PEEK material for the implementation of the PEEK cranial bone repair plastic surgery for Xiaohou. After the operation, Xiaohou not only restored the original appearance of the skull, but also greatly improved vision, mouth and nose skewed situation is also basically good. This young girl has regained her confidence and cheerfulness, and her family is very satisfied. Cranial defects may cause changes in the intracranial environment, intracranial pressure is unstable, cerebrospinal fluid circulation and blood circulation within the skull may be abnormal, brain nerve function may be affected, and vision loss may also occur. With PEEK Cranial Repair Plastic Surgery, the closed integrity of the cranial cavity can be restored after replacing the skull, providing a stable environment for the normal operation of cerebrospinal fluid circulation, blood circulation, and cerebral nerve function, and to a certain extent, vision can be improved as well. So it is possible to have an effect on vision restoration after cranial bone repair. At present, the new special polymer polyether ether ketone PEEK material with excellent performance is used, and technical improvement and material optimization design are constantly carried out, and the concept of cosmetic plastic surgery is also introduced, so as to comprehensively carry out the PEEK cranial bone repair and plastic surgery, which not only restores the intact cranial bone, which is helpful for the recovery of the brain, but also achieves a highly restorative, well-proportioned and beautiful appearance, which is highly praised.
