Polymethylmethacrylate for managing frontal bone deformities.

The correction of bony frontal deformities has been accomplished with a variety of autogenous and alloplastic materials. Of the various materials currently available, polymethylmethacrylate (PMMA), a valuable biomaterial, has proved to be effective in reconstructing deformities of the frontal bone. The authors present one case of acquired frontal bone deformity reconstructed by subperiostal application of PMMA through a minimally invasive coronal approach. Our preliminary experience with this method has been promising.
