Abstract
Objective: The primary objective of this study was to compare the applicability and benefit of providing unilateral cochlear implant (CI) users with a contralateral hearing aid (HA).Design: This retrospective (case-control) study was conducted in a hospital-based CI centre. Participants self-assessed their hearing via two questionnaires (SSQ12 and HISQUI19). Objective postoperative speech perception was assessed via aided thresholds and speech perception tests (monosyllabic words, disyllabic words, and sentences) in quiet and noise.Study sample: A CI-only group (n = 113, mean age 55.1 ± 14.2 years) and a bimodal group (n = 50, mean age 56.7 ± 15.2) participated in the study. Results: No significant difference in SSQ12 or HISQUI19 scores was observed between groups. The bimodal group had a significantly better aided hearing level (p = 0.020) and speech discrimination score (p = 0.019).Conclusions: Bimodal (CI + HA) users have significantly better speech understanding than unilateral CI-only users, although this benefit may not be reflected in self-assessed outcomes. Counselling about bimodal hearing must cover expectations about potential benefits.
