摘　　要：目的:比较3D外耳模型与外耳模片在一期耳廓再造中的临床应用效果,探讨3D打印技术在一期耳廓再造中的临床应用价值。方法:回顾性分析2018年1月-2020年12月在郑州大学第一附属医院医学美容中心行自体肋软骨一期耳廓再造术患者43例,其中25例术前通过激光三维扫描技术,对患侧耳进行数字模型重建,并借助3D打印技术制备患侧3D外耳模型,以此为模板行一期耳廓再造术(3D组);18例行外耳模片行一期耳廓再造术(模片组)。结果:经6个月随访,两组患者术后均恢复良好,再造耳外形满意逼真,未出现感染,支架暴露等并发症。两组再造耳形态耳宽/健侧耳形态耳宽及再造耳耳垂宽/健侧耳耳垂宽比较差异有统计学意义(P<0.05);但两组再造耳容貌耳长/健侧耳容貌耳长、再造耳容貌耳宽/健侧耳容貌耳宽和再造耳耳垂长/健侧耳耳垂长比较差异无统计学意义(P>0.05)。结论:在3D打印技术辅助下制备合适的3D外耳模型使用自体肋软骨对小耳畸形患者进行耳廓再造,术后患侧耳与健侧耳匹配,形态逼真,值得在临床上推广应用。Objective To compare the clinical effects of 3D external ear model and external ear mold in stage one auricle reconstruction.And to explore the clinical application value of 3D printing technology in stage one auricle reconstruction.Methods Retrospective analysis was made on 43 patients who underwent one-stage auricle reconstruction with autogenous costal cartilage in the Medical Beauty Center of the First Affiliated Hospital of Zhengzhou University from January 2018 to December 2020.The digital model of the affected ear was reconstructed by laser 3D scanning technology in 25 cases before operation,and the 3D external ear model of the affected ear was prepared by 3D printing technology,which was used as a template for one-stage auricle reconstruction(the 3D group).In 18 cases,stage one auricle reconstruction was performed with an external ear mold(the model group).Results After 6 months of follow-up,the two groups of patients recovered well after surgery.The shape of the reconstructed ear was satisfactory and lifelike,without infection,stent exposure and other complications.There were statistically significant difference between the two groups in terms of reconstructed ear shape ear width/healthy ear shape and reconstructed ear lobe width/healthy ear lobe width(P<0.05).There were no significant difference between the two groups in reconstructed ear physiognomic ear length/healthy side ear physiognomic ear length,reconstructed ear physiognomic ear breadth/healthy side ear physiognomic ear breadth and the earlobe length of the reconstructed ear lobes/the earlobe length of the healthy side ear lobes(P>0.05).Conclusion With the help of 3D printing technology,a proper 3D external ear model was prepared and autologous costal cartilage was used to reconstruct the whole ear of patients with microtia.The affected side ear was matched with the healthy side ear after the operation,with realistic morphology,which is worthy of clinical application.
