We report a technique of auricular replantation used in a case of traumatic amputation. The principal difficulties encountered in this type of replantation are mentioned, and ways of avoiding them are suggested. All the skin of the ear was removed except for that of the anterior surface of the conch. At this site, the cartilage received small, multiple perforations to allow for nutrition of the corresponding skin. The remainder of the auricular cartilage was covered by a skin flap undermined from the mastoid region. Three months later, the retro-auricular region was freed and covered with a total skin graft taken from the right supraclavicular region. On the basis of the satisfactory results obtained, we discuss the intention and the technical details of the method and possible contraindications.
我们报告了一例用于外伤性断耳再植的技术。文中提到了此类再植中遇到的主要困难，并提出了避免这些困难的方法。除了耳甲腔前表面的皮肤外，耳部所有皮肤均被切除。在此部位，软骨有多个小穿孔，以保证相应皮肤的营养供应。耳廓软骨的其余部分由从乳突区掀起的皮瓣覆盖。三个月后，耳后区域松解，用取自右锁骨上区的全厚皮片覆盖。基于所获得的满意结果，我们讨论了该方法的目的、技术细节及可能的禁忌证。
