Query: Models for Planning and Simulation in Computer Assisted Orthognatic
  Surgery   Two aspects required to establish a planning in orthognatic surgery are
addressed in this paper. First, a 3D cephalometric analysis, which is
clini-cally essential for the therapeutic decision. Then, an original method to
build a biomechanical model of patient face soft tissue, which provides
evaluation of the aesthetic outcomes of an intervention. Both points are
developed within a clinical application context for computer aided
maxillofacial surgery.
