Abstract
A 23-year-old man presented with an 8-year history of unilateral hemifacial microsomia. A three-dimensional model of the maxillofacial bones was generated after acquisition of helical computed tomographic data. A customised implant model was designed by projecting a mirror image of the healthy mandible on to the three-dimensional model. A resin model of the implant was then made using a rapid prototyping machine. A polymeric biomaterial was sculpted according to the model and implanted into the affected side of the mandible to restore his facial symmetry. The hemifacial microsomia was corrected and a symmetrical facial contour obtained. No complications developed during the 6-year follow-up.
