Since 2012 the transcutaneous bone conduction hearing implant Bonebridge (MedEl, Innsbruck, Austria) is used for patients with mixed or conductive hearing loss or single side deafness.


This study evaluates the experience of 31 patients (aged 3 – 38 years) with congenital aural atresia who have undergone audiologic rehabilitation using the Bonebridge implant between June 2012 and August 2017.


Air-conduction pure tone average was 63,98 dBHL (± 14,02 dBHL). Unaided average air-bone gap was 52,69 dBHL (± 15,74 dBHL).

Speech discrimination scores measured with Freiburger monosylable test at 65 dBSPL showed a significant continious improvement in quiet of 78,59% ± 24,57% (first fit), 91,88% ± 9,50% (3 months) up to 97,14% ± 4,10% after 6 months. The benefit became manifest after 6 months.


We see the significant hearing improvement as a result of implantation with stable results after 6 months of activation and a high level of satisfaction.
