title: [A preoperative planning system for unilateral craniofacial malformation restoration surgery based on the volume measurement of eye sockets].
abstract: The surgical treatment of craniofacial malformation is a sophisticated task which needs careful and detailed preoperative planning. However, based on the patient's 2-D CT and X-ray images, the surgeons always feel hard to produce a convincible and satisfying surgical scheme. In this article, a craniofacial surgery simulation system based upon 3-D reconstruction and volume calculation of two eye sockets is presented. By using this system, the surgeon can virtually repose bone fragment according to the D-value between the volumes of two eye sockets. The D-value serves as a guideline to direct the bone reposing. The simulated key steps of real surgical procedure are presented, which demonstrate the efficiency of the system. The contrast images between postoperative and preoperative surgery are also given.
