Xiao Dong in a sudden car accident in the unfortunate on-the-spot coma, the “inner shell” was seriously injured, craniocerebral injury. Sent to the local hospital for treatment, cranial CT examination suggests subdural hematoma, cerebral contusion, brain hernia formation, due to the critical situation, the doctor for him to do cerebral contusion removal and decompression of the flap, life can be saved, postoperative recovery is also good, but left behind the skull defects, frontotemporal parieto-occipital part of the cranium of a large area of the skull is missing. The cranial defect has dealt a huge blow to Xiaodong’s original self-confidence, and his originally cheerful personality has been gloomy and low-spirited, as he is unwilling to show his smile again. Because of the skull damage, Xiaodong’s brain and nerve functions were also affected. His eyesight dropped drastically, and his mouth and nose were crooked. He decided to cure his skull no matter what. Although the local hospital could repair the skull, the materials used to do so were very limited. So he came to our neurosurgery department for treatment. He came to our neurosurgery department to receive treatment because he learned that our hospital had very advanced materials for repairing the skull, which would enable him to return to a healthy life again. After Xiaodong was admitted to the hospital, after a series of checkups and evaluations, Director of Neurosurgery, Mr. Xing Bing, arranged for the staff to collect Xiaodong’s cranial CT data, and based on this 3D data, customized a PEEK material repair plate for him. Shortly afterward, Director Xing Bing performed the skull repair surgery for Xiaogang. After exposing the bone window during the surgery, the 3D prefabricated PEEK repair plate was tightly set into the bone window to achieve precise anatomical repositioning. After the operation, Xiaodong’s skull shape was restored intact and effective mechanical protection of brain tissue was realized. At the same time, the neurological function gradually improved, and he regained his beautiful and natural appearance. This surgery has brought back Xiao Dong’s self-confidence and happiness.
