Background: Total ear amputation is a rare accident. The most common causes are traffic accidents (33 %), followed by fights (28 %). In 1980, Pennington et al. reported the first successful microsurgical ear replantation in a 29-year old man.
Methods: An English literature review of trauma cases of total ear amputation showed only 13 successful replantations with arterial and venous microanastomoses. We present a case report of successful total ear replantation with arterial and vein microanastomoses in a 17-year old boy.
Results: Our ear replantation with both arterial and venous anastomoses performed was successful and we achieved an excellent aesthetic outcome.
Conclusion: The reason for such a low number of successful ear replantations is technical challenge due to small vessel diameter, difficult vessel identification, vessel approach and concomitant avulsion injury. The best aesthetic result in ear reconstruction is achieved by microsurgical replantation. The surgical technique depends on the intraoperative findings. Since ear replantation is a very challenging procedure, a microsurgeon needs to discuss with the patient the risk of partial/total necrosis of the replanted ear and the possibilities of other reconstructive options.
