Abstract/Summary This case study represents four years of audiological observations, testing and aural habilitation of a female child with a partial agenesis of the corpus callosum (ACC). The ACC was diagnosed by MRI scans to eliminate neurological causes for developmental delay at six months of age. This child was also born with a cleft palate and was diagnosed with Robinow Syndrome at 3 years and 3 months of age. The audiological results showed an improvement in hearing thresholds over the four-year period. The child’s opthamologist also reported an improvement in visual skills over time. The most interesting aspect of the child’s hearing was the discrepancy between the monaural and the binaural results. That is, when assessed binaurally she often presented with a mild to moderate mixed loss and when assessed monaurally she showed a moderate to severe mixed loss for the right ear and a severe mixed loss for the left ear. This discrepancy between binaural and monaural results was evident for both aided and unaided tests. Parental reports of the child’s hearing were consistent with the binaural clinical results. This case indicates the need for audiologists to: (a) carefully monitor the hearing of children with ACC, (b) obtain monaural and binaural hearing and aided thresholds results, and (c) compare these children’s functional abilities to the objective test results obtained. This case does question whether hearing aids are appropriate for children with ACC. If hearing aids are deemed to be appropriate, then hearing aids with compression characteristics should be considered.
