Retalhos cutâneos de avanço de ambas hemifaces para reconstrução do nariz após múltiplos carcinomas basocelulares no dorso nasal Bilateral facial cutaneous flaps for nose reconstruction after multiples basal cell carcinoma on dorsum of the nose

Resumo Os autores relatam caso de multiplos carcinomas basocelulares no dorso nasal, tratados com crioterapia, cirurgia e uso topico de 5-fluoracil. Os multiplos tumores nao foram recidivas de tumores anteriores, mas decorrentes da qualidade da pele do dorso nasal. Isto ficou evidente na biopsia apos a resseccao cirurgica, demonstrando ausencia de comprometimento nas margens da resseccao. A ulceracao por uso prolongado do 5-fluoracil ocorreu pela acao do quimioterapico sob o tecido normal. A retirada da pele do dorso ate a base da pirâmide nasal foi realizada para evitar novos tumores sobre a mesma. A reconstrucao por dois retalhos cutâneos de hemiface permitiu a reparacao do nariz, sem comprometer o contorno facial. Descritores: Carcinoma basocelular. Retalho Mustarde.

They were not recurrence of former tumors oc curring due to the poor skin quality. It was clearly showed through the biopsy exhibiting no BCC at the margin of resection. The wound caused by excessive use of 5-fluoracil was due to chemotherapy action over the normal skin. Removal of the skin from the dorsum to the base of the nose was performed to avoid new BCC. Reconstruction using cutaneous flaps on both sides of the face restored the nose and facial contour. Descriptors: Basal cell carcinoma. Mustarde Flap. Cutaneous flap.
