Abstract

CONCLUSION:

The study suggests that the Vibrant Soundbridge (VSB) middle ear implant could be a valid alternative for patients with congenital aural atresia to compensate for their hearing loss.

OBJECTIVE:

To determine the audiologic benefit the VSB provides in patients with congenital aural atresia.

METHODS:

Twelve patients with congenital aural atresia were implanted with VSB: eight patients were unilaterally atretic (67%) and 4 (33%) were bilaterally atretic. In five cases the implant was placed onto the round window, in another five cases the implant was placed on the stapes, in only one case a prosthesis (coupler) was used to fix the implant into the oval window, and in one case a fenestration on the cochlear endostium was performed.

RESULTS:

The mean functional gain obtained for all patients evaluated was 62 dB at 0.5 kHz, 60 dB at 1 kHz, 48.3 dB at 2 kHz, and 50.8 dB at 4 kHz. The mean functional gain for all frequencies evaluated was 55.1 dB.
