Reconstruction of contour and anterior wall defects of frontal bone with a porous polyethylene implant

Frontal bone contour defects cause marked facial deformity, which is instantly obvious to the observer. The aetiology is usually post-traumatic either following a traffic accident or a gunshot injury. The contour deformity of the frontal bone was reconstructed using Medpor porous polyethylene in 12 consecutive patients during a period of 2 years, In four of the patients, we used a coronal approach, whilst using the old incision scar and laceration for access in the remainder. In two of the patients it was not necessary to fis the implant at all, but the remainder were fixed with lag screws because of implant mobility, The aetiology, the technique used, and the results obtained are presented, (C) 1999 European Association for Cranio-Maxillofacial Surgery.
