Biomaterials for Reconstruction of Cranial Defects

Abstract

Cranioplasty is defined as the surgical repair of a cranial defect to restore the structure and function of the skull. Archaeological records show attempts of cranioplasty since the dawn of human civilization, but until today there is no consensus among neurosurgeons around the world-regarding the best material for cranioplasty. Relocation of the originally removed bone graft is still the best option, but is not always available. In modern cranioplasty, different materials can be used for the repair of cranial defects, such as metals, plastics, acrylics, and ceramics. Recent studies have sought to identify which materials provide the best long-term results, but scientific evidence is poor. Presurgical decisions must consider the experience of the surgical service and the individual conditions of the patient. In this study, we discuss the main characteristics of the materials used today for the reconstruction of cranial defects.
