Total auricular reconstruction for microtia is dependent on the fabricated three-dimensional costal cartilage framework, with all the auricular features and the skin flaps formed and utilized to cover the three-dimensional framework, in which extreme caution is required. Furthermore, other factors, such as contraction of the skin graft, use of the remnant ear cartilage in construction of the tragus, and the number of surgeries required, all affect the final results of total auricular reconstruction for microtia, especially with reference to the contour of the constructed ear, morphologic locations of the auricular features, contraction, circulatory dysfunction, resorption, etc. The grafting of the three-dimensional framework is the first stage of a two-stage surgical method for total auricular reconstruction without resorting to skin grafts, free composite grafts, and additional surgical procedures.
小耳畸形的全耳再造依赖于预制的三维肋软骨支架，需塑造出所有耳部特征，并形成和利用皮瓣覆盖三维支架，在此过程中需格外小心。此外，其他因素，如皮肤移植的收缩、在构建耳屏时使用残余耳软骨以及所需手术的次数等，都会影响小耳畸形全耳再造的最终效果，尤其是在构建耳的轮廓、耳部特征的形态位置、收缩、循环功能障碍、吸收等方面。三维支架的植入是两阶段全耳再造手术方法的第一阶段，该方法无需进行皮肤移植、游离复合移植及额外的手术操作。
