Cochlear implants work well in many profoundly deaf adults and children. However, despite the success of cochlear implants in many deaf children, large individual differences have been reported on a wide range of speech and language outcome measures. This finding is observed in all research centers around the world. Some children do extremely well with their cochlear implant while others derive...

Since the first cochlear implants (CI) were fitted in children with congenital and acquired deafness at the ENT Department of the Medical University of Hannover, with follow-up rehabilitation at the Cochlear Implant Centre Hannover (CIC), we have gained over ten years of experience in this field. Today the operation is a standard procedure. To date CI surgery has been performed in Hannover on s...

More than 60,000 people worldwide use cochlear implants as a means to restore functional hearing. Although individual performance variability is still high, an average implant user can talk on the phone in a quiet environment. Cochlear-implant research has also matured as a field, as evidenced by the exponential growth in both the patient population and scientific publication. The present repor...

Background: Cochlear implants are now an acceptable therapeutic option for those patients with irreversible hearing loss and deaf-mutism. The surgery is time consuming and complicated. Hence, the technique of anaesthesia plays a crucial role in success of cochlear implant surgery. Cochlear implant patients have various types of syndromes which are important from anaesthetic as well as surgical ...

OBJECTIVE To examine whether age at cochlear implantation or duration of implant use is associated with speech, language, and reading skills exhibited at age 8 to 9 years in children who underwent implantation by age 5 years. DESIGN Performance outcomes in speech perception, speech production, language, and reading were examined in terms of the age at which children first received a cochlear ...

This article reports the relationships between a large number of child and family related factors and children’s functional outcomes, according to parental report, in the domains of spoken language communication, social skills and participation, academic achievement, and independence and identity, through a series of step-wise regression analyses. Parents of 247 children who had received cochle...

Sound coding strategies for cochlear implants have evolved over the past 30 years with advances in research and technology. Processing schemes have transitioned from the delivery of a diffuse, broad signal in single channel devices to the transmission of detailed sound information to multi-channel devices. This evolution has involved the addition of more channels and more parameter options for ...
