Cost-Effective Patient-Specific Intraoperative Molded Cranioplasty

Abstract

Intraoperative molding of polymethyl-methacrylate into complex three-dimensional shapes with correct thickness is often a time-consuming process and may lead to unsatisfying cosmetical results. This article describes an intraoperative technique to assemble a polymethyl-methacrylate implant as a replica of the patient's bone flap. This approach provides a fast and inexpensive alternative technique with good cosmetic outcome. The technique is feasible and can be applied in early and delayed cranioplasty procedures. In selected patients, immediate single-stage reconstruction avoids a second operation
