Abstract
Objective To investigate the efficiency of rapid prototyping technology in repair of complex orbital injury.Methods The study involved 16 cases of complex orbital injury.Based on three-dimensional orbital reconstruction,the rapid prototyping technology was used to produce a l∶ 1 scale three-dimensional physical model.Treatment plans were developed with the aid of surgical simulation on the model and were practiced clinically.Results The model was created successfully in the study.Surgical incisions were all healed initially.Satisfactory facial shape,symmetrical orbit,normal ocular motility,and disappeared diplopia were achieved over 3 months to 3 years of follow-up.Conclusion A rapid prototyping model gives solid and accurate display of orbital three-dimensional anatomical structures and their interrelation and hence offers a vital basis for accurate understanding of malformation condition and rational design of surgical plans. Key words: Orbit ; Imaging, three-dimensional; Rapid prototyping
