Summary

Computer-aided design/manufacturing (CAD/CAM) created a precise, single-piece polymethyl methacrylate (PMMA) implant for a large bifrontal skull defect. This innovative approach successfully restored facial aesthetics and function, overcoming prior reconstruction challenges.

Area of Science:

Neurosurgery
Biomaterials Engineering
Medical Imaging

Background:

Large bifrontal defects present significant reconstruction challenges due to complex geometry and mechanical needs.

Keywords:

Cranioplasty Customization Decompressive craniectomy Large skull defect Polymethyl methacrylate
