In this paper we present two clinical cases in maxillofacial surgery, where complex surgical interventions have been pre-operatively planned on 3D models of the patients' heads. Our goal was to provide surgeons with an additional planning criterion, i.e. the prediction of the post-operative facial appearance. In our first study a two step mandibular distraction has been planned, and in the second one a bimaxillary operation with a high Le Fort I osteotomy of the maxilla according to Bell, as well as a sagittal split osteotomy on both sides of the mandible, according to Obwegeser-Dal Pont. Within our study we did focus on the three dimensional soft tissue simulation using finite element methods. For the provision of such a planning aid, concepts for an integrated 3D surgery planning system are proposed that are partially implemented and demonstrated.
