In auricular reconstruction, the convex structures of the framework determine the esthetics, and young doctors often need sufficient training to determine the best carving techniques. This study aimed to recommend optimal carving methods and provide measured data of convex structures of the carved costal cartilage framework to prevent complications, improve esthetics, and reduce the learning curve.
From 2018 to 2021, 406 patients with microtia who underwent costal cartilage carving were enrolled. The helix is formed by the eighth costal cartilage. The complex of the antihelix was fabricated from part of the eighth costal cartilage or the ninth costal cartilage. The tragus was constructed using residual cartilage pieces from the base frame. These components were measured, and those from the new ear graded "excellent" were used for data analysis. The statistical analysis was principally processed using Excel software.
A total of 112 ears were graded "excellent". The following are the mean and standard deviation of each group of data: antihelix thickness, 0.31 ± 0.06 cm; antihelix width, 0.40 ± 0.06 cm; superior crus thickness, 0.18 ± 0.04 cm; superior crus width, 0.38 ± 0.09 cm; inferior crus width, 0.22 ± 0.04 cm; inferior crus thickness, 0.28 ± 0.05 cm; helix thickness, 0.31 ± 0.04 cm; the four-point height of the helix, 0.52 ± 0.08 cm/0.51 ± 0.07 cm/0.46 ± 0.06 cm/0.41 ± 0.06 cm; and tragus height, 0.98 ± 0.15 cm.
These data may help beginners in reducing the learning curve of ear reconstruction. Framework fabrication based on these data allows attaining a harmonious ear framework and satisfactory three-dimensional auricle outline, yielding acceptable results and few complications.

在耳廓重建中，框架的凸面结构决定了外观，年轻医生通常需要足够的培训来确定最佳的雕刻技术。本研究旨在推荐最佳的雕刻方法，并提供雕刻肋软骨框架凸面结构的测量数据，以预防并发症、改善外观并减少学习曲线。
2018 年至 2021 年，共纳入 406 例接受肋软骨雕刻的小耳畸形患者。耳轮由第 8 肋软骨形成。对耳轮复合体由部分第 8 肋软骨或第 9 肋软骨制成。耳屏使用基架上的残余软骨片构建。对这些部件进行测量，并将来自新耳的“优秀”评级的部件用于数据分析。统计分析主要使用 Excel 软件进行处理。
共 112 只耳朵被评为“优秀”。以下是每组数据的平均值和标准差：对耳轮厚度，0.31±0.06cm；对耳轮宽度，0.40±0.06cm；上脚厚度，0.18±0.04cm；上脚宽度，0.38±0.09cm；下脚宽度，0.22±0.04cm；下脚厚度，0.28±0.05cm；耳轮厚度，0.31±0.04cm；耳轮四点高度，0.52±0.08cm/0.51±0.07cm/0.46±0.06cm/0.41±0.06cm；耳屏高度，0.98±0.15cm。
这些数据可能有助于初学者减少耳部重建的学习曲线。基于这些数据制作的框架可以实现和谐的耳框架和令人满意的三维耳廓轮廓，获得可接受的结果和较少的并发症。
