A case series of paediatric hearing preservation cochlear implantation: a new treatment modality for children with drug-induced or congenital partial deafness.

[pendred syndrome]

To investigate the use of hearing preservation cochlear implantation in children with partial deafness .Five children with either drug-induced or congenital partial deafness were enrolled in a pilot study . The patients ranged in age from 13 months to 14 years . Implantation was performed using a hearing preservation technique . A Flex EAS electrode (MED-EL , Innsbruck , Austria ) was used in all full insertions .L ow frequency hearing was preserved in all patients with postoperative bone conduction within 10 dB of the preoperative hearing levels . These changes were preserved over the follow-up period of 12 months . There were significant improvements in speech perception .Hearing preservation cochlear implantation is a new effective modality in children with partial deafness .
