Speech intelligibility and subjective benefit in single-sided deaf adults after cochlear implantation.

Treatment with cochlear implants (CIs) in single-sided deaf individuals started less than a decade ago. CIs can successfully reduce incapacitating tinnitus on the deaf ear and allow, so some extent, the restoration of binaural hearing. Until now, systematic evaluations of subjective CI benefit in post-lingually single-sided deaf individuals and analyses of speech intelligibility outcome for the CI in isolation have been lacking.

Performance groups in adult cochlear implant users: speech perception results from 1984 until today.

Introduction: More than 3,000 patients have received a cochlear implant in Hannover.

Methods: A group of 864 patients was selected from the main group for the analysis of speech perception development. Depending on the term of introduction of new implant technology, the viewed group was divided into 5 subgroups.
