Auris Nasus Larynx
October 2017
Objective: The aim of the study is to assess the audiological and surgical outcome after cochlear implantation in children with inner ear malformation and to compare them with a group of congenitally deaf children implantees without inner ear malformation.
Introduction: Children with profound sensorineural deafness with malformations of the inner ear represent a challenge, accounting to 5-15% of congenital sensorineural deafness. These cases were originally regarded as a contraindication for cochlear implant surgery.
Objectives: The purpose of this study was to review the outcomes of children with documented Waardenburg syndrome implanted in the ENT Department of Centro Hospitalar de Coimbra, concerning postoperative speech perception and production, in comparison to the rest of non-syndromic implanted children.
Methods: A retrospective chart review was performed for children congenitally deaf who had undergone cochlear implantation with multichannel implants, diagnosed as having Waardenburg syndrome, between 1992 and 2011. Postoperative performance outcomes were assessed and confronted with results obtained by children with non-syndromic congenital deafness also implanted in our department.
