title: The fate of an amputated nose after replantation.
abstract: Traumatic amputation of the nose is a challenging management problem. We describe the case of a 69-year-old woman who had a dog-bite nasal amputation. The avulsed piece, including the lobule, and approximately half of the columella and alae, was replanted within 2 hours of the trauma. Hyperbaric oxygen therapy was administered for 12 daily sessions. Skin gradually necrosed, and the eschar was tangentially excised. Almost all of the mucosa and of the cartilage layers survived and the final defect was smaller than the original. A 3-stage repair was performed by a paramedian forehead flap to replace cover. Lining was by approximation of native tissues, whereas framework was reinforced by conchal and septal cartilage grafts. The outcome was functionally and aesthetically satisfactory. Our case confirms that replantation of an amputated nose as a composite graft is worthwhile. Although the skin necrosed and required reconstruction, most of the lining and of the cartilage support survived, greatly improving the ease of reconstruction, as well as nasal function.
