Selleck AM, et al. - In this retrospective chart review, researchers identified the association of speech perception performance between pairs of pediatric siblings with severe to profound sensory hearing loss receiving cochlear implants and determined which factors negatively affected performance in cases of discordance in performance. The study sample consisted of 89 pediatric individuals, 43 sibling groups, under the age of 18 with severe to profound sensory hearing loss who received a cochlear implant with a sibling who also received a cochlear implant. According to results, pediatric siblings have a high correlation in the outcomes of speech perception after cochlear implantation, which suggests a strong role for the family environment. In conditions where there are significantly distinct results between siblings, higher depth of implant insertion is associated with better consonant-nucleus-consonant word scores.
