To report replantation of amputated ear with microtechnique in 5 cases. From 2002 to 2005, 5 totally amputated ears were replanted and 4 obediently, 1 retrogressively. In every case, 1-2 arteries and 1-3 veins were anastomosed. Seven vessels were detective and 1-6 cm vessels were transplanted from forearm or dorsal side of hand. Amputated ears obtained blood supply again in about 6-10 hours after injury and exploration was enforced for venous crisis in 2 cases, and bloodletting in 1 case. All 5 cases survived. Auricles possess perfect shape, no pigmentation, slight atrophy and perfect sensation. Amputated ear should be replanted as long as no obvious contusion occurred, and the keys to prevent vascular crisis are cutting off unhealthy vessels, grafting superficial veins for bridging, and the high quality of vascular anastomosis.
