The aftermath of cranial surgery is a cranial defect, if the cranial nerves are not injured during the surgery, there will not be any other aftermath. The treatment of cranial defects can also be very simple now, there are many other biological materials for the repair of cranial defects, such as titanium alloy, now titanium alloy can be reconstructed in three dimensions according to CT, which will be exactly the same as the original cranial bone, and there are also bone cements and plastic bone plates that can be used to complete the cranial defects, the surgery of cranial defects can be done directly in the first stage; it is possible to wait until half a year or a year after cranial defects, there are no other complications, and then it can be done again. Or you can wait until half a year or one year after the skull defect, when there are no other complications and no intracranial infections, then you can have the surgery to repair the skull defect.
