We have developed a simulation system called "NUCSS" for osteoplasty and in addition the "Surgi Plan" incorporating the most sophisticated version. Then, both these systems were compared regarding the hard aspect and principal performance and were fundamentally examined. As a result, when compared with NUCSS, the Surgi Plan having three-dimensional degree of freedom was seen as being the best. This enabled us to precise by process the actual surgical procedure. As to its clinical application, the Surgi Plan provided almost simular results as the postoperative three-dimensional CT images of the patient using craniofacial osteoplasty and patient having Chiari's pelviotomy.
