Objective:
Our purpose was to evaluate the results of Vibrant Soundbridge (VSB) in conductive or mixed hearing loss.
Materials And Methods:
Twenty-five adult patients (29 ears) with a mixed or conductive hearing loss and various etiologies were included in this retrospective study. The preoperative ipsilateral pure tone average was 71 ± 3.0 dB, and the average bone conduction threshold was 42 ± 2.8 dB (n = 29). The transducer was placed on the long apophysis of the incus (n = 16), in the round window (n = 10) or on the stapes (n = 3).
Results:
No complications were noted. The bone conduction threshold remained unchanged. VSB was activated in all cases. The postoperative pure tone average without VSB was 63 ± 3.9 dB (n = 24) and with VSB in free-field condition 24 ± 2.1 dB (n = 22).
Conclusions:
VSB is safe and efficacious for auditory rehabilitation in conductive and mixed hearing losses.
