However, as science progressed and the risks of each material used were understood, modern neurosurgery has a tendency to use either material coming from the patient itself or completely sterile materials crafted from non-biologic material (such as metal or various polymers) achieving in this way a rate of success of 99% in all patients [1,2].
Conclusions Scientists have always been on the search for the best materials to be used in calvarium repair.
