Decompression craniectomy is a surgical method used for immediate reduction of intracranial pressure. Repair of cranial bone defects to protect the brain and reconstruct the original cranial brain compartment is called a cranioplasty. In this study researchers will conduct research and compare storage of bone graft in the freezer with a temperature of -20 ° C and subcutaneous to the risk of infection. The research design used was paired clinical trials. Clinical tests were in open label form. The analysis of significance using the Mann Whitnay test showed that the value of p = 0.381. This means that there is no significant difference between the storage group in the subcutie and the storage group in the Cryopreservation (p> 0.05). The analysis of significance using the McNemar test showed that the p value = 0.003. This means that there is a significant relationship between the storage group in the subcutie and the storage group in the Cryopreservation (p <0.05).
