ABSTRACT

Introduction: The study of the final elongation values produced by 45º, 60º, 75º, and 90º-angle z-plasties performed on the skin of the lower abdomen of fresh cadavers were compared with the theoretical mathematical data published in the literature. Methods: Four z-plasties with 2-cm main and secondary branches each, and with 45º, 60º, 75º, and 90º angles were performed on the skin of the lower abdomen in 11 fresh cadavers to evaluate the final elongation produced. Results: The mean elongation at their respective angles was lower than that found in the literature, with a p value of <0.01. Conclusion: The elongation values obtained from the present study showed a significant difference from the published values.


Introdução: O estudo do alongamento final produzido por zetaplastias com ângulos de 45, 60, 75 e 90 graus na pele do abdome inferior de cadáveres frescos foi comparado com os dados matemáticos teóricos apresentados pela literatura. Métodos: Foram realizadas quatro zetaplastias com ramos principais e secundários de 2 cm cada um deles e ângulos de 45, 60, 75 e 90 graus na pele do abdome inferior de 11 cadáveres frescos para avaliar o alongamento final produzido. Resultados: A média dos alongamentos para os respectivos ângulos foi inferior ao encontrado na literatura, com valor de p < 0,01. Conclusão: Existiu diferença significativa entre os valores da literatura e os encontrados no presente estudo.
