[Surgical management of traumatic ear amputations: literature review]

Traumatic ear amputation (TEA) is a complete avulsion of a part or of the total auricular tissue. TEA are rare (only 74 cases have been described in the literature) and their handling is complex. The surgeon's objective is to obtain the best cosmetic result without demolishing the auricular area in order to allow future ear reconstruction in case of replantation failure. Many techniques of ear replantation have been described in the literature during the last 30 years: microsurgical replantation, pocket techniques and reattachment techniques. Microsurgical replantation should be achieved every time it is possible. When it is not possible, the surgeon can choose between ear reattachment and a pocket technique according to two clinical features: the size of the amputated part and the involvement of the ear lobe. Ear reattachment can be achieved when the amputated part is smaller than 15 mm or when amputation involves the earlobe. Pocket techniques, which are appropriate for the replantation of the auricular cartilage, can be used when the amputated part is bigger than 15 mm and does not comprise the earlobe.
