Objective:
To examine the outcomes of cochlear implantation in children with Pendred Syndrome.
Material And Methods:
A retrospective case series of nine pediatric patients with Pendred syndrome undergoing cochlear implantation at a tertiary academic medical center from 2003 to 2017.
Results:
All patients were diagnosed with bilateral mild-to-profound to severe-to-profound sensorineural hearing loss and used hearing aids prior to implantation. Preoperative imaging results revealed that all patients exhibited bilateral enlarged vestibular aqueducts and 8 of 9 had cochlear dysplasia equivalent to Incomplete Partition II. Despite inner ear malformations, all electrodes were successfully implanted with minimal complications and favorable post-operative audiological outcomes.
Conclusions:
Cochlear implantation is an effective and successful treatment for severe-to-profound hearing loss in children with Pendred syndrome and for whom traditional amplification aids provide limited benefit. With early intervention, cochlear implantation allows speech and cognitive development in Pendred children comparable to that of normal hearing individuals, allowing patients to learn in a mainstream educational setting.
