The purpose of this report is to evaluated the accuracy and potential advantages of the computer system in orthognathic surgery. The accuracy of computer prediction was evaluated in 31 patients by using the orthognathic surgery prediction expert system (OSPES) in the preoperative analysis, diagnosis, surgical simulation and preoperative facial appearance predication. This system could accurately predict the postoperative changing. The prediction accuracy for single-jaw surgery was over 95%; double-jaw 85%. The prediction for hard tissue was more accurate than that for soft tissue. The results of this study suggest that computer system is an acceptable tool for facial appearance prediction.
