This new method for total reconstruction of the auricle is a two-stage operation in which the first stage involves fabrication and grafting of a three-dimensional costal cartilage framework and the second stage is the ear elevation operation. The three-dimensional frame was designed with emphasis on the fabrication of the helical crus, intertragic notch, and antitragus and by extending the crus helicis and fixing it to the undersurface of the base frame. The reconstructed auricle will have four different floors: the cymba and cavum conchae are the bottom (fourth) level, the crus helicis is the third level, the fossa triangularis and the scapha are the second level, and the helix, anthelix, tragus, and antitragus are the top level. The skin incision was made in a W-shaped fashion to create skin flaps with ample surface area to cover the three-dimensional frame without skin grafting. Furthermore, the semilunar costal cartilage was utilized for ear elevation. Thus this new method for total reconstruction of the auricle eliminates the major problems encountered with the conventional method.
这种全耳廓再造的新方法是一种两阶段手术，其中第一阶段包括制作和移植三维肋软骨支架，第二阶段是耳部抬高手术。三维框架的设计重点在于制作耳轮脚、耳屏间切迹和对耳屏，并通过延伸耳轮脚并将其固定在基架的下表面。再造耳廓将有四个不同层次：耳甲艇和耳甲腔为底层（第四层），耳轮脚为第三层，三角窝和耳舟为第二层，耳轮、对耳轮、耳屏和对耳屏为顶层。皮肤切口呈W形，以形成具有足够表面积的皮瓣，无需植皮即可覆盖三维框架。此外，使用半月形肋软骨进行耳部抬高。因此，这种全耳廓再造的新方法消除了传统方法中遇到的主要问题。
