Ear reconstruction is one of the most challenging procedures for plastic surgeons. The costal cartilage is the most accepted material, and the framework fabrication methods also vary with the different ear reconstruction methods. This study aimed to present our clinical experience using a novel method for costal cartilage framework fabrication with the "fully expansion technique" ear reconstruction without a skin graft. From January 2017 to June 2018, 107 patients with unilateral microtia underwent ear reconstruction with the fully expansion technique. Costal cartilage was designed into different components and stacked up to form the multilayer structure and adequate projection. Preexpansion provided larger skin flap for fully cover the anterior and posterior parts of the framework. Then the anterior ear structures and the posterior sulcus, as well as the ideal bilateral symmetry, were established simultaneously without a skin graft. A total of 107 patients in this group were followed up for 8 to 24 month, and altogether 98 patients (91.6%) were satisfied with the reconstruction. The cartilage "stack-up" framework fabrication and fully expansion technique provided a well-defined, well-projected, and bilateral symmetrical reconstructed ear.
耳再造术是整形外科中最具挑战性的手术之一。肋软骨是最常被接受的材料，而框架制作方法也因不同的耳再造方法而有所不同。本研究旨在介绍我们使用“完全扩张技术”进行肋软骨框架制作的临床经验，该技术用于无需皮片移植的全扩张技术单侧小耳畸形耳再造。自 2017 年 1 月至 2018 年 6 月，107 例单侧小耳畸形患者采用全扩张技术进行耳再造。肋软骨设计成不同的组件，并堆叠起来形成多层结构和足够的突出度。预扩张为完全覆盖框架的前后面部提供了更大的皮瓣。然后，无需皮片移植，同时建立了前耳结构和后沟以及理想的双侧对称性。该组共 107 例患者随访 8 至 24 个月，共有 98 例（91.6%）患者对再造耳满意。软骨“堆叠”框架制作和全扩张技术提供了一个轮廓清晰、突出度良好且双侧对称的再造耳。
