What material was used for the cranioplasty in the right cranial defect case?

Reconstructing a skull defect often needs a material that can be shaped precisely to fit an irregular contour while providing solid protection for the brain. Methyl methacrylate (PMMA) is a moldable bone cement that can be sculpted intraoperatively to match the defect and then hardens into a durable, protective shell. When a wire mesh is used as a scaffold, it gives PMMA a stable frame to attach to and helps maintain correct contour and position, especially around the edges of the defect. This combination combines ease of shaping, good immediate protection, and cost-effectiveness. Other options have their own tradeoffs. Titanium mesh is strong and biocompatible but more expensive and less forgiving to contouring during surgery. A bone graft uses the patient’s own bone but can resorb or be insufficient for large defects. Stainless steel has corrosion and biocompatibility concerns, making it less favorable for cranial reconstruction. In this case, the surgeons chose the versatile, adaptable PMMA reinforced with wire mesh to restore the skull’s shape and function.
