Abstract：Objective To investigate the value of a 3D model in guiding auricular framework carving for skin expansion auricle reconstruction.Methods Retrospective analysis was performed on 40 patients who underwent unilateral second-stage auricle reconstruction.The patients were divided into 2 groups with 20 cases per group.Two-dimensional ear model using traditional film was employed in group A,and 3D ear models were used in group B.In the process of auricular framework carving,the 2D ear model was regarded as a guideline in group A,while both 2D ear model and mirror 3D models of the contralateral ear were regarded as a guideline in group B.Results (1)The duration of auricular framework carving.There was significant difference between group A and group B (P＜0.05).The duration of auricular framework carvingin group A was longer than that in group B.(2)Match between reconstructed ear and normal ear.There was significant difference between group A and group B (P＜0.05).The appearance of the reconstructed ear was more similar to the contralateral side in group B than that in group A.The satisfaction of patients was higher in group B.Conclusion The application of 3D models in auricular framework carving of skin expansion auricle reconstruction can significantly shorten operation time.It can offer better guidance for more personal and precise auricular framework carving.
