The skull is the protective umbrella of the human cranium, and once the skull is damaged, the human brain, sensory organs, as well as the digestive and respiratory apparatus can be significantly affected. Therefore, timely cranial repair is particularly important and can generally be performed within 3 months of recovery from trauma or surgery. There is no exact value for the approximate cost of cranial repair surgery, because each patient with cranial defect is different, and the cost of repair materials, hospitalization, examination, surgery and other aspects need to be evaluated to determine the exact cost. It is worth mentioning that the skull repair can promote some neurological recovery. When the neurological function is well recovered, it will help the patient to recover the memory as soon as possible. In addition, skull repair can also restore the normal shape of the patient’s head and increase the safety of the patient. With the protection of the skull, it can effectively avoid the re-injury of brain tissue and various adverse reactions. In addition, the repair material directly affects the overall recovery of the patient after surgery. Advanced repair materials cause less discomfort and faster recovery time after surgery. With defective repair materials, not only will various discomforts occur after surgery, but it is also likely that the patient will need to undergo secondary repair due to material exposure, which will also increase the patient’s economic pressure to a certain extent.
