[A study of computer aided simulation system for orthognathic surgery].
How easily to stimulate the orthognathic surgery with high accuracy and good reliability and visually explain the prediction of surgery to the patient with maxillomandibular deformities remains a key focus in oral and maxillofacial surgery. A Computer Aided Simulation System for Orthognathic Surgery (CASSOS) was developed by means of the technique of digital image processing, with which a detailed analysis could automatically be performed, including 71 measurements of distance, degree and ratio for frontal cephalograms and 68 measurements for lateral one with a computer aided diagnosis. A quantitatively surgical simulation for prediction of operation could satisfactorily be done for the clinical use. All data and images were printed by laserjet and color video printer. All procedures were finished in 20 minutes.
