Should we provide cochlear implants earlier for children with large vestibular aqueduct syndrome?
Patterson and colleagues (2021) examined outcomes of nine pediatric patients with Pendred syndrome who received cochlear implants between 2003–2017.
Pendred syndrome is an autosomal recessive disorder defined by the combination of sensorineural hearing loss, goiter and an enlarged vestibular aqueduct (EVA). All patients had bilateral mild to profound sensorineural hearing loss, used hearing aids prior to cochlear implantation, and had enlarged vestibular aqueducts. Eight of the nine participants had cochlear dysplasia. The age at implantation was between nine months and seven years.
All electrodes were successfully implanted into the scala tympani, and all patients had good postoperative audiological outcomes. Postoperatively, the average AzBio sentence score was 97 percent. The patients were enrolled in a mainstream educational setting or early intervention school setting and were using remote microphone technology at school.
The authors concluded that cochlear implantation is an effective and successful treatment for children with Pendred syndrome for whom traditional amplification provide limited benefit. Outcomes have been proven highly successful overall with a low rate of complications despite the abnormal inner ear anatomy (Hall et al 2019).

In a recent study, Mahendran and colleagues (2021) sought to compare the rates of cochlear implant (CI) referral and implantation across different races and to compare audiometric profiles of the patients via retrospective analysis. Demographic and audiometric data were collected for 504 patients between 2010–2020 who underwent CI evaluation or implantation. Of those, 388 met…
Cochlear implantation is generally considered a safe and effective recommendation for healthy adults who have bilateral, moderate-to-severe or moderate-to-profound sensorineural hearing loss and do not benefit from acoustic amplification (i.e., poor speech recognition). However, given the large elderly population and the importance of timely hearing intervention, there is a need to more closely examine the…
Do you work with older adults who have both hearing loss and reduced physical functioning? If so, you will want to read a recent article by Martinez-Amezcua and colleagues (2021) who reported a significant association between hearing loss and reduced physical functioning. These authors also reported an association between hearing loss and reduced walking endurance. …
