Abstract
Background and objectives

Keloid scars occur when, compared to normal healing, there is excessive formation of collagen after skin wounds or burns. Different treatments have been tried, though no particular one has been shown to be superior. The objective of this study was to assess the usefulness of the surgical technique originally described as keloid fillet flap in the management of relapsing keloids of the pinna.

Material and methods

The study included 10 patients (8 men, 9 white and 1 black) with a keloid on the retroauricular region or earlobe of more than 1 year duration, who had undergone previous treatment (surgery and topical or injected corticosteroids) without a good outcome or with relapse, and who had not received any treatment in the previous 6 months.

Results

Five patients were treated with a fillet flap procedure only, while the other 5, in addition to the procedure, also applied 5% imiquimod cream 5 times a week for 1 to 3 months. In 4 patients, no relapse was observed after the intervention. Two patients had partial flap necrosis, with subsequent partial relapse in one of these. Eighty percent reported the outcome of the procedure as good or excellent.

Conclusion

We achieved a response rate of 40% in the treatment of relapsing keloid of the pinna by a fillet flap procedure. This may be an alternative within the therapeutic arsenal for the treatment of relapsing keloid of the pinna, given that it does not require extensive resources and the skills needed to perform the procedure can be quickly acquired.

Resumen
Introducción y objetivos

El queloide se caracteriza por la formación excesiva de colágeno respecto a la cicatrización normal y puede aparecer de forma secundaria tras una herida o quemadura cutánea. Para su corrección se han ensayado diversos tratamientos, sin que ninguno haya demostrado su superioridad. El objetivo de este estudio es valorar la utilidad de la técnica quirúrgica originalmente descrita como keloid fillet flap (colgajo «en filete») para el tratamiento de queloides auriculares recidivantes.

Material y métodos

Se seleccionaron diez pacientes (ocho varones, nueve de raza blanca, uno de raza negra) con queloide retroauricular o de lóbulo recidivante de más de un año de evolución, que habían recibido tratamiento previo (cirugía y corticoides tópicos o en infiltración) sin resultado o con recidiva, y que no habían recibido ningún tipo de tratamiento en los últimos seis meses.

Resultados

Cinco pacientes fueron tratados quirúrgicamente solo con colgajo «en filete» y otros cinco con colgajo e imiquimod crema al 5% cinco veces por semana durante uno a tres meses. En cuatro pacientes no se apreció recidiva tras la intervención. Dos pacientes presentaron necrosis parcial del colgajo, uno de los cuales desarrolló recidiva parcial de la lesión. El 80% calificó el resultado de la intervención como bueno o excelente.

Conclusiones

Hemos conseguido un 40% de respuesta en el tratamiento del queloide auricular recidivante mediante la realización de colgajo «en filete». Este puede representar una alternativa dentro del arsenal terapéutico disponible para el tratamiento del queloide auricular recidivante, dado que no necesita de grandes medios y puede realizarse después de un entrenamiento mínimo.
