Abstract
Introduction and objectives

In certain situations (“high risk perforations”) such as large perforations, revision cases, middle ear pathology, eustachian tube dysfunction and atelectatic ears, the failure rate for myringoplasty is high. Some authors have suggested that the materials most frequently used for myringoplasty (fascia and perichondrium) may play a role in this failure rate. Cartilage myringoplasty, however, achieves good results in these “high risk” cases. The purpose of this study was to analyse our results and describe the technique.

Methods

A retrospective study of all consecutive patient charts for cartilage myringoplasties performed in a 5-year period (2002–2007) was carried out.

Results

During the study period, cartilage was used in 99 patients (122 cases). More than 66% of the cases were large perforations and 26% of the cases were revision cases. Successful closure was achieved in 92% of the cases and the functional results showed improvement in the air-bone gap average with statistical significance for type I tympanoplasty.

Discussion

The reconstruction of tympanic membrane perforations with cartilage is recommended in certain cases (“high risk” perforations). The results described here show that the anatomical and functional results are good and we consider the technique easy to learn.

Conclusions

We consider cartilage myringoplasty to be a technique that can be used in “high risk” perforations where a technique using fascia or perichondrium may have a higher risk of failure.

Resumen
Introducción y objetivos

En las perforaciones timpánicas con “alto riesgo” de fracaso como son perforaciones grandes, anteriores y/o peritubáricas, reperforaciones, patología de mucosa de oído medio, disfunción tubárica, atelectasia, etc., el porcentaje de fracaso de las miringoplastias es más elevado. Se ha descrito que los materiales que clásicamente se emplean en las miringoplastias (fascia y pericondrio) pueden jugar un papel en este hecho y la miringoplastia con cartílago ofrece mejores resultados. En este trabajo exponemos nuestra experiencia con la miringoplastia con cartílago y describimos la técnica empleada.

Métodos

Estudio retrospectivo donde se revisan las historias clínicas de miringoplastias con cartílago realizadas de forma consecutiva durante un periodo de 5 años (2002–2007).

Resultados

Se estudia una muestra de 99 pacientes y 122 intervenciones. Más del 66% de los casos son perforaciones que afectan a más de 3 cuadrantes de la membrana y el 26% de los casos fueron cirugías de revisión tras fracasos previos. A pesar de estos datos a priori desfavorables, la tasa de cierre de perforación de esta serie de 122 casos es del 92%. Los resultados funcionales en los casos de timpanoplastia tipo I muestran una mejoría de la transmisión aérea media con valores estadísticamente significativos.

Discusión

Consideramos que la reconstrucción de los defectos timpánicos con cartílago es una alternativa recomendable en determinados casos que denominamos casos de “alto riesgo”. Los resultados de esta serie ponen de manifiesto este hecho y además consideramos que son reproducibles de forma sencilla.

Conclusiones

Creemos que la miringoplastia con cartílago debe ser tenida en cuenta en los casos que a priori sean desfavorables y donde una miringoplastia con uso de fascia o pericondrio puede fracasar.
