It has become much more accurate in recent years thanks to the advent of osteosynthesis plates and the contribution of three-dimensional imaging. Three-dimensional imaging makes it possible to simulate fairly accurately the surgical procedures and bone displacements required. However, the effect of these bone displacements on the soft tissues (skin, subcutaneous tissue, muscles) does not make it possible, with today's digital tools, to simulate the final aesthetic result and in particular to anticipate the sometimes significant postoperative changes to the face. Many patients are worried about these post-operative morphological changes and would like to have a precise idea of how they will look after su
