Abstract
Objective To explore the impact of autologous costal cartilage transplantation assisted with three dimensiona(3D)printing technology on repair of moderate to severe cup ear deformity.Methods A total of 72 patients with moderate to severe cup ear deformity who underwent autologous costal cartilage transplantation in Suining Central Hospital from December 2019 to December 2021 were collected.On the basis of ear mold making,patients were divided into standard ear molding group(n=36,two-dimensional standard ear molding)and 3D ear molding group(n=36,preoperative 3D printing technology).Morphology of reconstructed ear,psychological state,complications,aesthetic satisfaction and application effect of model were compared between the two groups.Results Score of contour,symmetry,cranio-auricular angle and reduction of sub-anatomical structure of reconstructed auricle in 3D group were higher than those in standard group at 6 months after operation,there was no remarkable difference in score of size and position between the two groups(P＞0.05).The scores of anxiety,depression,paranoia,fear and inferiority in both groups were lower after surgery than before surgery,and the 3D modeling group was lower than the standard eardrum group(P＜0.05).Incidence of complications in 3D group was lower than that in standard group,but there was no noteworthy difference between the two groups(P＞0.05).Aesthetic effect and model application effect score of 3D group was signally higher than that of standard group(P＜0.05),there was no conspicuous difference in stability satisfaction between the two groups(P＞0.05).Conclusion 3D printing assist with autologous costal cartilage transplantation in treatment of moderate to severe cup ear deformity help to reconstruct fine anatomical structure of ear,improve the psychological state,reduce occurrence of complications and improve satisfaction of aesthetic effect.It has important promotion significance for better implementation of auricle reconstruction.关键词
