A modified methylmethacrylate cranioplasty is presented. After preparation of the skull defect, a Teflon net is placed and fitted over it, overlapping the border by one centimeter. The plastic material is spread over the Teflon net in the skull defect and is removed as soon as it becomes firm. Next, the plate is perforated at several points and then is fixed with Vicryl stiches between the Teflon net and the epicranium. This procedure is simple and fast. The fixation is firm; the result is good.
