    "abstract": "This paper proposes a computer-assisted system for the surgical treatment of\nexophthalmia. This treatment is classically characterized by a de-compression\nof the orbit, by the mean of an orbital walls osteotomy. The plan-ning of this\nosteotomy consists in defining the size and the location of the de-compression\nhole. A biomechanical model of the orbital soft tissues and its in-teractions\nwith the walls are provided here, in order to help surgeons in the definition\nof the osteotomy planning. The model is defined by a generic Finite Element\nporo-elastic mesh of the orbit. This generic model is automatically adapted to\nthe morphologies of four patients, extracted from TDM exams. Four different FE\nmodels are then generated and used to simulate osteotomies in the maxillary or\nethmoid sinuses regions. Heterogeneous results are observed, with different\nbackwards movements of the ocular globe according to the size and/or the\nlocation of the hole.",
