A method comprising: transforming a three-dimensional image representing at least features craniofacial bone tissue of a patient in an interactive two-dimensional image representing the same features craniofacial bone tissue of a patient by defining a base ellipse further defines a plane xy coordinates for the three-dimensional image and by defining a base circle which has its center at the origin of the coordinate plane xy, then transforming the two dimensional image in an intermediate image by mapping the base ellipse in base circle, then transforming the intermediate image in a linear profile which forms the interactive two-dimensional image having one or more associated portions each with a corresponding portion of a trait craniofacial bone tissue and containing at least one polygon or point of control over the image superimposed in at least one location display one or more interactive two-dimensional images so that a user can, through an input device user, causing movement of at least one of the one or more portions of such two-dimensional image to simulate the movement of the corresponding portion the patients bone tissue in osteotomy procedure displaying a three-dimensional image representing Craniofacial features external soft tissue of the patient receiving input from a user on the movement of a particular portion of one or more portions of the two-dimensional image, wherein the input causes movement of at least one polygon or control point to at least a new location and redraw the three-dimensional image based at least in the movement of the particular portion of the two dimensional image to simulate the response of the cranio-facial features of tissue outside soft patient movement of a portion of bone tissue corresponding patient to particular portion of the two-dimensional image, wherein the re-drawing uses at least one location of at least one polygon or checkpoint.Un método que comprende: transformar una imagen tridimensional que representa al menos ra
