Implant-retained auricular prostheses are a successful treatment modality for children with microtia. They involve only minor surgical intervention of implant placement and result in an esthetically pleasing outcome. Integration of digital technologies (DT) in the prosthetic reconstruction process is a new approach toward enhancing outcomes. In this report we present a case of auricular prosthetic reconstruction following two implant placements in the right mastoid region. The ear prosthesis was constructed with the aid of various DTs. A structured light laser scanner was used to digitize the nondefect patient ear. The digitized 3D ear was then manipulated in specialist software, mirrored to reflect the opposing side, and a Rapid Prototyping (RP) machine (Z-Corp) was used to manufacture the soft tissue required. This RP-mirrored ear model allows very accurate reproduction to replicate missing soft tissue. A color Spectrometer was used to accurately reproduce skin tones. The use of these technologies is now routine practice at our unit. They enhance prosthetic outcomes and esthetics, save the prosthetist's time, and are digitally stored and subsequently readily available and reproducible.
植入式耳赝复体是治疗小耳畸形儿童的一种成功的治疗方法。它们只需要进行微小的植入物放置手术，就能获得令人满意的美学效果。将数字技术 (DT) 整合到修复体重建过程中是一种提高治疗效果的新方法。在本报告中，我们介绍了一例在右侧乳突区进行两次植入物放置后进行耳廓修复体重建的病例。耳假体的制作借助于各种 DT 完成。使用结构光激光扫描仪对非缺损患者的耳朵进行数字化。然后在专业软件中对数字化的 3D 耳朵进行操作，将其镜像以反映对侧，再使用快速成型 (RP) 机 (Z-Corp) 制造所需的软组织。这种 RP 镜像耳朵模型可以非常精确地复制缺失的软组织。使用分光光度计准确复制肤色。我们单位现在已经常规使用这些技术。它们可以增强修复体的效果和美观度，节省修复体技师的时间，并且可以数字化存储，随后可以随时方便地再现。
