Abstract

Simulation and three-dimensional visualization of object motion is a prerequisite for any surgical planning system. Orbital hypertelorism is a disease, which is most commonly associated with craniofacial malformations. We have developed a surgical planning system for planning and evaluation of orbital hypertelorism surgery. In our system CT-based virtual surface models fitted by oriented bounding boxes (OBB) are manipulated. Three-dimensional motion as well as a correction surgery can be simulated. Both are controlled by collision detection. The computer-based interactive surgery simulation systems (CISSS) presented here can take virtual surgical operation and forecast facial features after the correction of orbital hypertelorism, our surgical planning is cheaper and faster than the current methods, surgical outcome was also better than the current methods.
