Objectives:
Previous research has shown the positive effects of cochlear implantation in children with a short duration of single sided deafness (SSD). This case series assessed the impact of cochlear implantation in a cohort of children with a longer average duration of SSD.
Methods:
A retrospective chart review of 6 children who received a cochlear implant for SSD. The mean age at time of cochlear implantation was 14.7 years old (median = 15.5, interquartile range (IQR) = 2.5) and mean duration of hearing loss before cochlear implantation was 10.8 years (median = 11.5, IQR = 5.3). Pre- and post-operative audiometric data for aided speech perception testing, sentence recognition in quiet, sentence recognition in noise, and word recognition scores were analyzed.
Results:
When compared to preoperative hearing aid scores a 24% significant increase in median word score and a 64% significant increase in median sentence recognition score in quiet was observed at 12 months post-op.
Conclusion:
Cochlear implantation in children with a longer duration of SSD can provide benefit to speech recognition.
Lay Summary:
This retrospective case series of children with prolonged single sided deafness demonstrated an improvement in word and sentence recognition within 12 months of receiving a cochlear implant.
