title: Use of image-guiding template for contouring surgery of midfacial fibrous dysplasia.
abstract: Simulation surgery using a 3-dimensional model is common in treatment of the craniofacial region. However, designing the reduction volume on the affected region and precise contouring according to a simulation model are still difficult. We developed a template composed of a thin clear dental plastic plate, which fits on the reduction model obtained from simulation surgery. We made several holes on the reduction model covered with the template and measured the depth of each hole without the template, which represents the thickness to be contoured at each point. This template was a mold of the reduction model and guided contouring of deformed bones intraoperatively. We applied the template to the affected region and marked the outline of the template and points of the holes. With the image designed with this template, we could contour the deformity of midfacial fibrous dysplasia symmetrically and easily.
