| Introduction: Auditory neuropathy spectrum disorder (ANSD) is a pattern of hearing loss
characterized by preservation of outer hair cell function despite severe damage
or absent brainstem auditory evoked responses. Management of children with ANSD
is debatable. The purposes of the
current study were to compare the effect of cochlear implantation on these
developmental skills of children with and without ANSD and to investigate the
age of cochlear implant reception on language (receptive and expressive) and
speech skills of children. Materials and Methods: This cross-sectional analytic study was conducted between eight cochlear
implanted children with ANSD and eight match children with profound
sensory-neural hearing loss (SNHL). Newsha developmental scale was used to
evaluate three investigated skills. Results: Significant correlation was shown between the age of hearing loss
diagnosis and the score levels in three developmental skills (p < 0.012).
All children were lingered in the investigated skills compared to normal
hearing children however, there was no significant difference between the
cochlear implanted children with and without ANSD (p ≥ 0.636). Conclusion: The receptive language, expressive language and speech skills of children
with ANSD and their matches were the same. It seems that cochlear implantation
can be considered as an appropriate approach in the management of these children,
especially at lower ages. |
