Retalho Romboide: Variantes e Aplicações.

Abstract

O retalho romboide foi inicialmente descrito por Alexander Limberg e posteriormente modificado por Claude Dufourmentel e R.C. Webster. Numerosas alterações a estas variantes foram propostas ao longo dos anos por vários autores para solucionar defeitos dermatológicos em várias áreas corporais. Este artigo pretende fazer uma revisão sistemática da bibliografia disponível, procurando expor de forma clara e concisa os princípios dos retalhos deste tipo utilizados na prática clínica e as suas diferentes aplicações consoante a localização e características do defeito a corrigir.O retalho romboide é por definição um retalho simples, uni-lobulado de transposição. Em geometria, um um rombo é um paralelogramo equilátero, também designado por losango. Um romboide é qualquer paralelogramo com os lados adjacentes diferentes e ângulos oblíquos. O retalho de Limberg é, por definição geométrica, um rombo para lesões da pele com ângulos de 60 e 120º.O retalho de Dufourmentel é uma modificação do retalho de Limberg, em que apesar de os lados do rombo se manterem iguais, a diagonal menor vai variando de tamanho consoante a amplitude do ângulo agudo. Assim, obtém-se um rombo formado por dois triângulos isósceles em vez de equiláteros, como no caso do retalho de Limberg.O retalho de Webster tem um planeamento e execução mais complexos que os anteriores retalhos. Consiste na combinação do retalho de Limberg com uma plastia em "M" de forma a diminuir o ângulo do retalho para 30º, conseguindo desta forma uma distribuição de tensão da pele mais uniforme.A escolha de um retalho para a correcção de uma lesão cutânea é multifatorial, sendo necessário o cirurgião dominar estas técnicas para que possa tomar a melhor decisão para o doente.

The rhomboid flap was initially described by Alexander Limberg and later modified by Claude Dufourmentel and R.C. Webster.Numerous alterations to these variants were proposed throughout the ears by various authors in order to correct different cutaneous defects. This article intends to do a revision in order to clearly expose the principles of this kind of flaps and their different aplications according to the location and característics of the cutaneous defect.The rhomboid flap is by definition a simple, uni-lobulated transposition flap. In geometry a rhombus is an equilateral paralelogram, also known as a diamond. A rhomboid is a paralelogram with different adjacent sides and oblique angles. The Limberg flap is by geometric definition, a rhombus for a cutaneous defet of 60 and 120º.The Dufourmentel flap is a modification of the Limberg flap where besides the sides of the rhombus stay the same, the minor diagonal varies in size according to the amplitude of the acute angle. Thus obtaining a rhombus formed by two isosceles triangles insted of equilateral, such is the case in the Limberg flap.The Webster flap has a more complex execution and planing than the previous flaps. It consists in the combination of the Limberg flap with an "M" plasty in order to shorten the angle of the flap to 30º, thus achieving a more uniform skin tension.Since the choice of a flap for the correction of a cutaneous defect is multifactorial, the surgeon must master these techniques in order to make the best decision for the patient.
