RESUMEN
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.

The paper describes a new, simple, selective and precise high-performance thin-layer chromatographic (HPTLC) method for the simultaneous identification and quantitative determination of boric acid (BA) and calcium fructoborate (CFB) in bulk and tablet/capsule dosage forms of dietary supplements. HPTLC silica gel G 60 F254 precoated glass plates were used as the stationary phase. The mobile phase consisted of 2-propanol-water 8:2 (v/v). The two boron-based compounds were adequately separated with the Rf values of 0.83 ± 0.01 (BA) and 0.59 ± 0.01 (CFB).
