Report about 12 cases of defect of the frontal bone: state after radical operation of the frontal sinus (Riedel's operation) or after removal of bone splinters after injury. 6--12 months later a paladon-inlay (acrylate prosthesis) can be implanted to fill the defect and to restore the profile. Description of the production, forming, sterilization and operative implantation of the prosthesis. The patients have been observed up to 18 years. In one case the implanted material was removed after 10 years because of recurrent local suppurations.
