Fully implantable hearing device in isolated congenital external ear canal atresia

Abstract

Aural atresia is the congenital malformation of the ear characterized by partial or complete atresia of the external ear. Our aim is to show the effectiveness of the MET Fully-Implantable Ossicular Stimulator (FIMOS) Carina® in the treatment of hearing loss with auricular atresia. In this case, we experienced The MET Fully-Implantable Ossicular Stimulator (FIMOS) Carina® to the patient who has bilaterally congenital external ear canal atresia for rehabilitation of hearing loss. In postoperative sixth month audiological test the mean functional gain in a four frequency pure-tone average was approximately 39 dB HL. The capacity of the Carina® MET ossicular stimulator to provide appropriate gain relative to the degree of hearing loss indicates that the device may be a viable treatment for patients with agenesis of external auditory canal and severe malformation of the middle ear.

İzole konjenital dış kulak yolu atrezisinde tamamı implante edilebilen işitme cihazı uygulaması

Öz

Dış kulak yolu atrezisi, dış kulak yolunun kısmi veya tam gelişim defekti ile karakterize bir konjenital malformasyonudur. Çalışmamızdaki amacımız MET Fully-Implantable Ossicular Stimulator (FIMOS) Carina® ile tadavi edilen bilateral aural atrezi olgusunun sonuçlarını tartışmaktır. Bilateral konjenital aural atrezisi olan işitme kayıplı hasta tamamı implante edilebilen MET Fully-Implantable Ossicular Stimulator (FIMOS) Carina® ile tedavi edilmiştir. Hastanın postoperatif 6. ay odyolojik değerlendirilmesinde saf ses odyometrisinde ortalama 39 dB HL kazancı saptanmıştır. Carina® MET kemikcik zincir uyarımı ile yeteri kadar işitme kazancı sağlamış olup, bilateral aural atrezisi olan kişilerde tedavi amaçlı kullanılabilinir.
