Microvascular ear replantation is a significant challenge because of the small size of the vessels and the fact that traumatic amputations are frequently avulsed. The zone of trauma is therefore extended and the primary repair of the injured vessel is rendered unlikely. The purpose of this study is to review the literature of ear replantation. A review of the relevant literature that has been published since 1980 revealed 47 cases reported in 37 publications. We present 5 cases from our own experience and analyze a total 52 cases of microvascular ear replantation. The patient's age, sex, degree of amputation, cause of injury, ischemic time, method of arterial and venous anastomosis, complications, any additional outflow used, postoperative medications, the requirement for transfusions, and the number of hospital admission days are described. Successful microvascular ear replantations require anastomosis of the vessels if possible. Rather than a vein graft, primary repair of the vessels, or at least pedicled repair of the artery, should be considered to ensure flap survival. In addition, vein repair should be considered if possible to ensure the secure drainage of blood from the replant. With secure circulation, the replant can survive, resulting in a very satisfactory outcome.

Microvascular salvage of a thrombosed total ear replant

Microvascular replantation, when possible, is the treatment of choice for total ear amputations. Both arterial and venous reconstruction should be attempted. The present case report describes a successful total ear replantation in a 45-year-old woman whose ear was amputated due to a horse accident. Venous thrombosis subsequently occurred and was managed with anticoagulation and leech therapy. Eighty hours after the replantation, arterial thrombosis took place. The posterior auricular artery thrombosed anastomosis was resected and reconstructed with an interposition vein graft. This report illustrates the feasibility of the successful microvascular salvage of a thrombosed total ear replant. It suggests the need for close clinical monitoring of the replanted ear and prompt microvascular reexploration in an event of the loss of arterial flow.

Using an unconventional perfusion pattern in ear replantation-arterialization of the venous system

Ear amputation is a devastating injury characterized by a conspicuous deformity that is not easily concealed and can result in tremendous psychological trauma in addition to the physical insult. While numerous different approaches have been proposed, microvascular replantation is widely considered to deliver the best esthetic outcome. In this article, the authors report a case in which an unconventional perfusion pattern (i.e., arterialization of the venous system) was chosen, as intraoperative anatomic conditions precluded conventional vascular reconstruction. A 25-year-old male patient sustained a human bite resulting in subtotal amputation of his left ear. In the setting of an adequate arterial donor vessel, that is, branch of the posterior auricular artery, and a single suitable recipient vein (0.4 mm), the decision was made to perform an end-to-end arterio-venous anastomosis without the use of vein grafts. Medicinal leeches were applied postoperatively to provide for venous drainage. The ear survived and the patient was discharged after 14 days. To the best of our knowledge, this is first case of a subtotal ear amputation that was successfully replanted by arterialization of the venous system without the use of vein grafts and with preservation of the superficial temporal vessels.
