Arterial only anastomosis associated with modified Baudet technique in ear replantation: Case reports and literature review
Case reports with literature review published in Medicine (2021)
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.

Resumen
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.
Por qué esto importa para la hirudoterapia
El resumen reporta tres pacientes masculinos con amputación total de la oreja (Weerda grado IV) que fueron sometidos a reimplante microquirúrgico mediante anastomosis solo arterial con una técnica de Baudet modificada, en la que incisiones en el cartílago ampliaron el área de contacto entre el cartílago y el sitio receptor. Se utilizaron sanguijuelas medicinales para tratar la congestión venosa postoperatoria, suplementadas con terapia anticoagulante sistémica, con supervivencia de todo el segmento reimplantado en los tres casos y buenos resultados funcionales y estéticos. La conclusión establece que la hirudoterapia ayuda a aliviar la congestión venosa temprana. Para la ASH, esto es directamente relevante para la hirudoterapia como coadyuvante clínico en el reimplante auricular cuando no se realiza anastomosis venosa. Los hallazgos se limitan a tres casos sin grupo control.
