摘　　要：3D打印技术在医学领域的应用是与CT、MRI、激光扫描数据的3D重构技术相结合,使其形成精度极高、外形极其逼真的结构模型,从而实现个体化的植入材料制造。由于不同病例的情况千差万别,这种个体化的制造对于整形外科耳廓再造是非常重要的,同时也是制备组织工程细胞外支架结构的一个理想解决途径。在耳缺损修复手术中,3D打印技术重建缺损耳的3D立体结构,用于术前建模指导手术、耳廓支架的雕刻,将天然生物材料和高分子材料通过3D打印构建成具有复杂外部形状和精细内部结构的外耳廓支架,减少手术次数的同时也减轻了患者取自体肋软骨带来的痛苦。本文就3D打印技术及应用、耳廓再造术的发展,以及耳支架的高分子材料及生物材料方面作一综述。Three-dimensional （3D） printing technology which is combined with CT, magnetic resonance imaging （MRI）, and 3D reconstruction of laser scan data in the field of medicine constructs the structural model with high precision, extremely realistic appearance to achieve individualized implant material. Due to the different circumstances of cases, the individualized implant material which is an ideal solution to prepare tissue engineering scaffold is very important for the individualized orthopedic auricle reconstruction. In the ear surgery to repair the defect, the 3D structure of defect ear reconstructed by 3D printing technology is used for preoperative surgical modeling guidance and ear bracket carving. The natural biological materials and polymer materials were constructed into auricle scaffold with complex external shape and fine internal structure, reducing the number of operations and relieving the pain of taking rib cartilage from patients themselves. The development and application of 3D printing technology, auricle reconstruction, polymer materials and biomaterials of auricle scaffold were introduced in the paper.
