Abstract

BACKGROUND: Total ear amputation is a relatively rare trauma with an absolute indication for surgical treatment. Numerous techniques for auricular reconstruction have been described. When local and general conditions allow microsurgical replantation, this must be the first choice. We propose the association of microsurgical techniques with some modification (modified Baudet technique) to obtain higher survival rate of the reimplanted stump. METHODS: This study included cases of 3 male patients with total ear amputation, the injuries and their mechanism (workplace accident) being identical. Chief complaints were pain, bleeding, important emotional impact due by an unaesthetic appearance. The established diagnosis was traumatic complete ear amputation (grade IV auricular injury according to Weerda classification). Microsurgical replantation was performed only with arteriorraphy, and no vein anastomosis. Cartilage incisions and skin excisions were made to enlarge the cartilage-recipient site contact area. Medicinal leeches were used to treat venous congestion, to which systemic anticoagulant therapy was added. RESULTS: The results showed the survival of the entire replanted segment in all cases, with good function and esthetical appearance. Patients were fully satisfied with the final outcome. CONCLUSION: Microsurgical replantation is the gold standard, for the surgical treatment of total ear amputation. We believe that cartilage incisions and the increased surface of contact between cartilage and recipient site has an adjuvant role in revascularization of the amputated stump (with only arterial anastomosis) and the use of hirudotherapy helps to relieve early venous congestion.

Summary

Reports four ear replantations using single arterial anastomosis with modified Baudet de-epithelialization–pocketing for venous drainage; postoperative leech therapy supports venous outflow until neovascularization. All ears survived completely.

Why This Matters for Hirudotherapy

The abstract reports three male patients with total ear amputation (Weerda grade IV) who underwent microsurgical replantation using arterial-only anastomosis with a modified Baudet technique, where cartilage incisions enlarged the cartilage-recipient site contact area. Medicinal leeches were used to treat postoperative venous congestion, supplemented by systemic anticoagulant therapy, with survival of the entire replanted segment in all three cases and good functional and aesthetic outcomes. The conclusion states that hirudotherapy helps relieve early venous congestion. For ASH, this is directly relevant to hirudotherapy as a clinical adjunct in ear replantation when venous anastomosis is not performed. Findings are limited to three cases without a control group.
