The correction of contour defects of the frontal bone has been accomplished with a variety of autogenous and alloplastic materials. We report our experience in reconstructing 11 cases of congenital, traumatic, and postsurgical frontal defects with acrylic. The acrylic was cured intraoperatively within the defect in some patients, or prefabricated into a prosthesis and wired into position in others. The operative techniques for both methods of repair are detailed. The reconstruction was successful in all cases and there were no complications. The acrylic implant has been found to be well tolerated after 2–10 yr follow‐up. The value of the construction of a facial moulage is stressed, especially when restoration of the orbital rim is required.
