    Introduction:

    To evaluate the long-term safety and performance of four different 2nd generation Vibroplasty-Couplers in combination with an active middle ear implant the Vibrant Soundbridge in a prospective multicenter study.

    Methods:

    At Twenty-four subjects Warble tone thresholds and Freiburger monosyllable word recognition scores at 65 dB SPL (WRS) were measured by pre- and post-operatively. To determine patient satisfaction, an established quality-of-life questionnaire developed for conventional hearing aids (cHAs) usage was administered to all subjects.

    Results:

    Mean functional gain for all couplers investigated was 38.8 dB at 36 months post-operatively. Mean WRSs improved from 2.9% to 67.08% in the aided situation. WRS improvements for all coupler groups were significant. The signal to noise ratio (SNR) improved by 5.9 dB SNR over the unaided condition. High subjective device satisfaction was reflected by the International Inventory for Hearing Aids (IOI-HA) scored very positively.

    Conclusions:

    Vibroplasty Couplers of the 2nd generation are safe and effective in the long time follow up and yield good subjective device satisfaction after Vibrant Soundbridge implantation.
