Abstract
Background

Cartilage-cutting and cartilage-sparing techniques are the two types of otoplasty procedures. Because of the significant risk of haematoma, skin necrosis, and ear deformity, cartilage-cutting techniques have been questioned. As a result; suture-based cartilage-sparing procedures such as Mustarde and Furnas suture procedures have grown in popularity. However, these techniques have a tendency for deformity recurrence due to cartilage memory and suture fatigue, as well as the possibility of suture extrusion and pinpricking sensation of the sutures.

Methods

In this study, we used a medially based adipo-dermal flap including perichondrium which is elevated from the back of the auricle to cover and support a cartilage-sparing otoplasty, thirty-four patients (14 female and 20 male) were operated using this technique. The medially based perichondrio-adipo-dermal flap is advanced anteriorly and fixed to the helical rim under cover of the distal skin flap. This procedure sought to cover the suture line preventing suture extrusion and support in the repair of the deformity preventing its recurrence.

Results

The average operative time was 80min, ranging from 65 to 110min. The patients passed the early postoperative period uneventfully except for 2 patients; one patient (2.9%) developed haematoma, and the other patient developed a small area of necrosis on the new antihelical fold. In late the postoperative period recurrence of the deformity developed in one patient. No patients developed suture extrusion or granuloma.

Conclusion

The treatment to repair prominent ears is easy and safe, with benefits such as a natural-looking antihelical fold and minimal tissue stress. The medially or proximally based adipo-dermal flap may help to lower recurrence rates and suture extrusion.

Resumen
Antecedentes

El recorte y la remodelación del cartílago son los dos tipos de técnicas en los procedimientos de otoplastia. Debido al riesgo considerable de hematoma, necrosis cutánea y deformidad de la oreja, las técnicas de recorte del cartílago han sido cuestionadas. Como resultado, los procedimientos de remodelación del cartílago basados en sutura, tales como las técnicas de Mustarde y de Furnas, han ganado popularidad. Sin embargo, dichas técnicas tienden a recidivar la deformidad debido a la memoria del cartílago y a la fatiga de la sutura, así como hay la posibilidad de extrusión y de la sensación de pinchazo en ellas.

Métodos

En el presente estudio utilizamos un colgajo pericondrial-adipo-dérmico con base medial que se eleva desde el dorso auricular para cubrir y soportar la otoplastia de remodelación del cartílago, habiendo operado a 34 pacientes con esta técnica (14 mujeres y 20 varones). El colgajo pericondrial-adipo-dérmico con base medial se avanza anteriormente y se fija al borde helical inferior para cubrir el colgajo cutáneo distal. El objetivo de este procedimiento fue cubrir la línea de la sutura, impidiendo la extrusión de la misma, y soportar la reparación de la deformidad previniendo su recidiva.

Resultados

El tiempo quirúrgico medio fue de 80min, fluctuando de 65 a 110min, transcurriendo el periodo postoperatorio temprano de los pacientes con normalidad, excepto en dos pacientes: uno de ellos (2,9%) desarrolló hematoma y el otro desarrolló una zona pequeña de necrosis en el nuevo pliegue antihelical. En el periodo postoperatorio posterior un paciente desarrolló recidiva de la deformidad. Ningún paciente desarrolló extrusión de la sutura ni granuloma.

Conclusión

El tratamiento reparador de las orejas prominentes es fácil y seguro, con beneficios tales como el aspecto natural del pliegue antihelical y el estrés tisular mínimo. El colgajo adipo-dérmico con base medial o proximal puede ayudar a conseguir menores tasas de recidiva y de extrusión de la sutura.
