title: Impact simulation on pre-formed prosthesis for large cranial defect.
abstract: Cranioplasty greater than 10 cm2 in size is challenging task for neurosurgeon. There are many successful trials to fill the small defect with various materials. Proper cranioplasty can provide subsequently restoration of cerebral protection, cosmetic aspect and neuronal function. However, larger defect may not provide adequate protection from the auto, industrial or sport accident even with cranioplasty. In this study, patch design using two popular materials was evaluated and compared with bone material. Then impact-releasing holes were implemented to the patch. The movement of the large patch and its effect on the underlying brain tissue upon simulated impact was evaluated by using finite element analysis.
