From 1980 to 1993 there have been five reports of ear replantation or reconstruction using microsurgical techniques. They are A) successful replantation of a completely avulsed ear by microsurgical anastomosis'; B) microsurgical reattachment of totally amputated ears2; C) completely successful replantation of an amputated ear by microvascular anastomosis3; D) microvascular ear replantation with no vein anastomosis4; and E) reconstruction of an avulsed ear by constructing a composite free flap.5 The first four reports of completely avulsed ears were successfully replanted with microvascular anastomosis. The last report was of an avulsed ear whose cartilage was buried into the forearm skin and 6 months later the composite forearm flap was transferred into the ear region by microvascular anastomosis. These reports confirmed that ear reconstruction could be completely successful by microsurgical methods. It must be emphasized that microsurgical ear reconstruction is suitable especially for those patients in whom the ear defect resulted from severe burning or avulsion of scalp with an avulsed ear. In these cases there is no normal tissue around the ear region that can be used for routine local flap reconstruction.From December 1990 to October 1993 we performed 3 cases of successful ear reconstruction using microsurgical methods for 2 patients with burn defects and for 1 patient with an avulsed scalp. SURGICAL METHODSThe surgical procedure is divided into two stages. The composite forearm flap is prepared at the first stage. In the second stage, the composite forearm flap is transferred to the ear region for ear reconstruction.In the first stage, portions of the 6th, 7th, and 8th rib cartilages were removed and carved into a cartilage framework for ear reconstruction. The framework was then buried under the skin of the forearm. In this step, the direction of the reconstructed ear and its relationship between the forearm flap and radial vessels must be considered carefully.More than 3 months later the second stage procedure is performed. The prepared composite cartilage-forearm flap is isolated in the same manner as a free forearm flap. Care must be taken to avoid exposure of the cartilage and to ensure that the vascular pedicle will be long enough. The flap is then transferred to the head, and the vessel anastomoses performed. A split skin graft is used to resurface the back of the reconstructed ear. The defect of the radial artery may be restored by a vein graft and the forearm skin donor site is resurfaced with a full-thickness graft. CASE REPORTS Case 1A 22-year-old male with a burn scar over his left face, temple, and ear region was admitted for repair of his left face and ear (Fig. 1).In December 1990 a lateral thorax flap was transferred to resurface his left face. At the same operation a costal cartilage ear framework was carved and buried into the left forearm just under the skin. Thus, we prepared a composite forearm flap for ear reconstruction. Four months later the second stage was undertaken.In the second p...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
