Long-Term Clinical Outcome Analysis of Poly-Methyl-Methacrylate Cranioplasty for Large Skull Defects

The results of previous studies have shown that infection and complication rates of cranioplasties accomplished with bone cement are substantially higher, that titanium-based implants may obscure follow-up imaging for tumor patients, and that the outcomes regarding hydroxyapatite-based ceramics, although similar to PMMA, are associated with a much higher cost. PMMA remains a cost-effective and proven method to repair cranial defects that fulfills the goals of cranial reconstruction for skull defects.
