Speech perception in noise by children with Mondini dysplasia who had undergone cochlear implantation

Abstract

Objectives

Assessment of verbal and auditory capabilities in children with ‘incomplete partition type 2’, after cochlear implant may help to better determination of the appropriateness of this method in these children.

Methods

In this comparative study, 21 cases with cochlear implant that had ‘incomplete partition type 2’ were enrolled and compared with 35 cochlear implanted cases with no inner ear malformations as control subjects. Then the speech and hearing ability tests including speech intelligibility rating (SIR), Categories of Auditory Perception scale (CAP), consonant-vowel (CV) in noise, word-in-noise (WIN), and quick speech-in-noise (QSIN) were measured in both groups of case and control were determined and compared across the groups.

Results

The results of tests including SIR, CAP, CV in noise, and word in noise were same across the groups (p > 0.05). The only differed item was speech in noise (p = 0.003).

Conclusion

Cochlear implant results in same efficacy in verbal capabilities in children with and without inner ear abnormalities. Hence, use of this method is accompanied with successful results even in children with inner ear abnormalities.
