Pinna synthetic mold for otoplasty techniques application

Abstract Introduction The ear deformity Tanzer type V, also known as prominent ears, is the most common genetic defect of the pinna. The surgery designed for its correction is known as otoplasty. This esthetic surgery can be performed using different techniques, which requires great skill of its operator. Objective The purpose of this work is the development of a new tool for otoplasty techniques training, aimed on the possibility to minimize errors during the otoplasty. Methods Synthetic molds of the external ear from patients with Tanzer type V deformity were made, using silicone material and rayon. Results The main procedures of otoplasty could be performed in the molds made of silicone and rayon with a good esthetic result. Conclusion The elaborated molds had identical size and shape of a human ear and could be positioned in the same shape of the patient ears. Thus, the synthetic molds were presented as promising simulation tools for the training and surgical enhancement of otoplasty, especially for doctors beginners.

摘要：引言 谭泽尔V型（Tanzer type V）耳部畸形，又称招风耳，是临床最为常见的耳廓遗传性缺陷。用于矫正该畸形的手术称为耳整形术（otoplasty）。该美容整形手术可通过多种不同术式实施，对术者的操作技能要求颇高。
目的：本研究旨在开发一款全新的耳整形术技术训练工具，以最大限度减少耳整形手术过程中的操作失误。
方法：针对罹患谭泽尔V型耳部畸形的患者，采用硅酮材料与粘胶纤维（rayon）制作其外耳的合成模具。
结果：采用该硅酮-粘胶纤维复合材料制作的模具可完整开展耳整形术的核心操作步骤，且能获得良好的美学修复效果。
结论：所制备的合成模具与人类耳廓的尺寸、形态完全一致，且可按照患者耳部的自然形态进行安置。综上，该合成模具可作为极具应用前景的模拟训练工具，用于耳整形术的技能培训与手术操作精进，尤其适合入门医师的学习实践。
