Abstract

In the last several years, bone anchored hearing aids have proven to be useful in treating conductive and mixed unilateral or bilateral hearing loss, as well as for sensorineural unilateral hearing loss. The Sophono Alpha 1 model has the advantage of not requiring an abutment, with it being coupled by magnetism instead. We report the cases of 3 infants with congenital malformations of external and middle ear. Audiometry showed conductive hearing loss. All 3 patients were implanted with Alpha 1 model (Sophono). Patients evolved satisfactorily. After 30 days we applied the processor and the control audiometry showed a marked improvement of hearing thresholds, although without a complete closure of the gap. With minimal care, the skin over the implant remained in excellent condition, with a very satisfactory cosmetic outcome.

Resumen

En los últimos años los implantes osteointegrados han probado su utilidad en el tratamiento de la hipoacusia de transmisión mixta, uni o bilateral, y la neurosensorial unilateral. El implante Alpha 1 de Sophono ofrece una ventaja sustancial, la falta de acoplador externo y su unión al receptor por medio de magnetismo. Presentamos el caso de 3 niños que padecen malformaciones de oído externo y medio de origen congénito. Los estudios audiométricos revelan hipoacusias de transmisión de carácter moderado. En los 3 pacientes se propuso la colocación del implante Alpha 1 de Sophono. Los pacientes evolucionaron de forma satisfactoria. A los 30 días se les aplicó el procesador, y en las audiometrías de control se evidenció una notable mejoría de los umbrales auditivos, aunque sin conseguir un cierre completo del umbral diferencial auditivo. Con cuidados mínimos, la piel sobre el implante se mantuvo en excelentes condiciones, siendo el resultado estético inmejorable.
