One of the hazards involving bone grafts inserted for correction of a nose is the possibility of shifting despite proper positioning at the time of the operation. In order to eliminate this occurrence, the graft should be fixed firmly. By means of a depression made in the desired nasofrontal osseous region for reception of its cephalic surface, the implant becomes anchored. The pit is made by glabella perforators. These two similar-shaped instruments have handles with 4 in. shanks and round cutting burs of two sizes, one, 3 mm., the other 4 mm., with a small rim behind each belly which limits deeper penetration. The bony implants are secured in the nasofrontal region by first making a depression with the smaller-sized hand bur to a depth of about 2 to 3 mm. This is replaced by the larger bur, and an adequately sized pocket is made for the reception of the
