摘　　要：目的探讨在3D打印技术辅助下应用自体肋软骨在儿童个体化耳廓再造中的优势。方法河南省人民医院整形外科2019年8月-2021年9月收治的70例小耳畸形患者,随机分为研究组和对照组,每组35人,分别用3D打印技术制作的3D打印耳模和传统的胶片耳模作为模版术中雕刻。结果术后6个月复诊照相,由术者,第三方整形医生及家属对研究组再造耳廓外形的总体评价的优良率为94.3%,对照组的优良率为77.1%,P=0.003<0.050,差异有统计学意义。结论在3D打印技术辅助下的运用自体肋软骨对儿童小耳畸形患者进行全耳再造,形态更加逼真,立体感更强,患者家属及医生的满意度认可度更高,值得在临床上推广和应用。Objective To explore the advantages of using autologous costal cartilage for the reconstruction of children's individual auricles in children with Craniomaxillofacial asymmetry with the aid of 3D printing technology.Methods From August 2019 to September 2021,70 patients with microtia were treated in the Plastic Surgery Department of Henan Provincial People's Hospital.They were randomly divided into the study group and the control group,with 35 patients in each group.3D printed ear molds and traditional film earmould were used as stenographic engraving.Results Six months after the surgery,the overall evaluation rate of the reconstruction auricle shape by the surgeon,third-party plastic surgeons and family members was 94.3% in the study group and 77.1% in the control group,P=0.003<0.050,and the difference was statistically significant.Conclusion With the aid of 3D printing technology,the use of autologous costal cartilage for the reconstruction of patients with craniomaxillofacial asymmetry and microtia,the position is more symmetrical,the shape is realistic,the stereoscopic effect is strong,the patient's family and doctor's satisfaction is high,it is worthy of clinical Promotion and application.
