Mono-syllabic word test score as a pre-operative assessment criterion for cochlear implant candidature in adults with acquired hearing loss.

Rationale: Cochlear Implant (CI) candidates with a ski-slope hearing loss may be outside current implantation criteria [< 50% on Bamford-Kowal-Bench (BKB) sentence testing], despite having a significant hearing disability and limited benefit from conventional amplification.

Aim: To use existing post-operative performance data to establish a criterion for Arthur Boothroyd (AB) word test for CI candidacy assessment.

Methodology: Retrospective analysis of post-operative AB words scores for 64 CI users was performed and the 10th percentile score selected as a criterion of reasonable chance for post-operative improvement.

Evaluation of bilaterally implanted adult subjects with the nucleus 24 cochlear implant system.

Objective: To evaluate the speech perception benefits of bilateral implantation for subjects who already have one implant.

Study Design: Repeated measures.

Patients: Thirty adult cochlear implant users who received their second implant from 1 to 7 years with a mean of 3 years after their first device.
