The outcome of cochlear implantation among children with genetic syndromes.

OBJECTIVE

To assess the outcome and efficacy of cochlear implantation in children with genetic syndromes.

METHOD: Study design: case-control study.

SETTING

A cochlear implantation tertiary referral center.

PATIENTS: All pediatric cochlear implantation recipients with Waardenburg syndrome, Usher syndrome, Dandy-Walker syndrome, or albinism. A control group was appropriately matched to the syndromic group with regard to age at implantation and duration of device use.

INTERVENTION: Cochlear implantation.

MAIN OUTCOME MEASURES: Subjects' auditory abilities, speech intelligibility, and pure tone thresholds were compared between the syndromic and non-syndromic group.

RESULTS

A total of 25 subjects (13 syndromic and 12 non-syndromic) participated in the study. Neither auditory ability nor speech intelligibility scores differed significantly by group. The final PTA of both the groups showed normal-to-mild hearing loss: 26 dB HL in the syndromic group and 23 dB HL for the control group.

CONCLUSIONS

Cochlear implant recipients with genetic syndromes achieved similar levels auditory perception and speech intelligibility as their peers with a genetic syndrome. The presence of any of the genetic syndromes described herein should not be a contraindication to cochlear implant provision, as it would have a positive impact on the patients' sensory perception and lifestyle.
