The surgical reconstruction of congenitally missing or malformed ears is challenging and involves complicated surgeries. Ear shape, position, and skin color will likely be compromised in patients with relative anatomic symmetry, and it is easier to reproduce these features with a prosthesis. This article describes the prosthetic reconstruction of 3 patients who had received failed or suboptimal surgical reconstruction of their missing or deformed ears. Challenging characteristics included limited soft-tissue availability, skeletal hypoplasia with prominent concavity defect, and bilaterally missing ears with abnormally low hairline. Three-dimensional planning using a software program was used to determine the ideal implant locations and mirror the contralateral ear. The mirrored ear was 3-dimensionally printed with a stereolithography printer. The skin color was reproduced digitally by using the Spectromatch Pro system.
先天性耳部缺失或畸形的外科重建具有挑战性，且涉及复杂的手术。相对解剖结构对称的患者，其耳朵形状、位置和肤色可能会受到影响，而使用假体更容易重现这些特征。本文描述了3例接受耳部缺失或畸形手术重建失败或效果欠佳患者的假体重建情况。具有挑战性的特征包括软组织可利用性有限、骨骼发育不全伴明显的凹陷性缺损，以及双侧耳部缺失且发际线异常低。使用软件程序进行三维规划，以确定理想的植入位置并镜像对侧耳朵。使用立体光刻打印机对镜像耳朵进行三维打印。通过Spectromatch Pro系统以数字方式重现肤色。
