Abstract
Background: Annually an estimated 223 children in the UK are born with or acquire permanent profound bilateral deafness (PBHL ≥ 95 dB). These children may gain little or no benefit from acoustic hearing aids. However, cochlear implants might enable them to hear. Objectives of the review: To bring together the diverse research in this area under the rigor of a systematic review to discover the strength of evidence when comparing the effectiveness of unilateral cochlear implants with non‐technological support or acoustic hearing aids in children with PBHL. Type of review: Systematic review. Search strategy: This examined 16 electronic data bases, plus bibliographies and references for published and unpublished studies. Evaluation method: Abstracts were independently assessed against inclusion criteria by two researchers, results were compared and disagreements resolved. Included papers were then retrieved and further independently assessed in a similar way. Remaining studies had their data independently extracted by one of five reviewers and checked by another reviewer. Results: From 1,580 abstracts and titles 15 studies were included. These were of moderate to poor quality. The large amount of heterogeneity in design and outcomes precluded meta‐analysis. However, all studies reported that unilateral cochlear implants improved scores on all outcome measures. Additionally five economic evaluations found unilateral cochlear implants to be cost‐effective for profoundly deaf children at UK implant centres. Conclusions: The robustness of systematic review methods gives weight to the positive findings of 15 papers reporting on this subject that they individually lack; while an RCT to show this would be unethical.
