Objective:
This article aims to demonstrate that children with asymmetric hearing loss (AHL), specifically those with single side deafness (SSD condition) and pure SSD, with substantial hearing (>70% normal speech discrimination) in the ear with hearing aid (HA), obtain clinically relevant speech perception benefit after cochlear implantation in the contralateral side.
Results:
Retrospective study of two groups: (1) 36 AHL children with bimodal hearing and (2) SSD children with SSD. They had follow-ups of 24 and 12 months duration, respectively. The AHL children where implanted on one ear and depending on the contralateral ear condition, they were divided into two groups: children who reach a disyllabic speech test score lower than 50% in quiet at 65dB-SPL without lip reading (27) and children with test score higher than 70% (9). The second group consisted on 2 children implanted to obtain SSD condition, as preliminary data, with 1 year of follow-up. They showed benefits of binaural stimulation.
Conclusion:
Children in a bimodal situation, with substantial hearing (>70% speech discrimination) in the ear with HA, obtain clinically relevant speech perception benefit after cochlear implantation in the contralateral side.
