Usefulness of measuring electrically evoked auditory brainstem responses in children with inner ear malformations during cochlear implantation

Abstract

Of the 25 ears lacking any malformation, 21, three, and one showed 'Good', 'Variable', and 'No' ECAP responses, respectively, and 24 and one showed 'Good' and 'Variable' intra-cochlear responses, respectively. Of the 15 ears with a malformation, two showed 'Good' ECAP responses, nine had 'Variable' ECAP responses, and four showed 'No' ECAP responses. Moreover, five showed 'Good' EABR responses and 10 showed 'Variable' EABR responses.
