Abstract
Background
There have been many reports on replantation of complete auricle amputation, but few reports on successful replantation of partial auricle amputation. The main reason is that the diameter of blood vessels at the end of auricle is only 0.3 mm, and it is difficult to find suitable blood vessels, especially venous vessels. The purpose of this study was to investigate the method of revascularization after partial auricle amputation.
Methods
Microvascular repairs were performed in an amputated segment with only identified artery vessels for anastomosis, and vein was unavailable for anastomosis. Postoperative acupuncture bloodletting and heparin compress treatments were planned.
Results
Two patients with partial ear amputation were treated at our center between 2019 and 2021. All the amputated ear were replanted successfully. No blood transfusions and no infections were observed. A week later the replanted auricles were seen, blood flow established.
Conclusion
Microvascular repair should be considered as the best options in cases of auricular avulsion segment replantation. When no vein was available for anastomosis, only one artery repaired was feasible. Acupuncture bloodletting and heparin compress are the effective methods to treat vein congestion.
