Abstract

Cranioplasty for large cranial defects greater than 10 cm² is a still challenge to neurosurgeons because of insufficient materials and strength. Polymethylmethacrylate (PMMA) generates chemical heat and fumes that cause tissue necrosis and delayed bone growth. Hydroxyapatite (HA) is not recommended for larger cranial defects. Large defects may not provide appropriate underlying cerebral protection from direct trauma even after cranioplasty. In this study, we investigated cranial prosthesis with pellet structures that facilitate stress redistribution upon impact
