Future Directions for Cochlear Implants Orientations futures pour les implants cochleaires

چکیده
Cochlear implants have provided the opportunity for many postIingually deafened adults to hear. Results from sophisticated multichannel implants show a very wide range of performance across patients. We review some of these findings and present a method for measuring lipreading enhancement by considering the percentage of possible enhancement. Prelingually deafened children with cochlear implants are able to recognize some of the important speech features, although their progress is slow. Future improvements in understanding signals and noise, in signal processing, in optimizing device adjustments, in surgical procedures, and in rehabilitation will contribute to the development of this field. Resume Grace aux implants cochleaires, de nombreux adultes atteints de surdite postlinguistique peuvent entendre. Les resultats d'implants multi-mnaux perfectionnes revelent des performances tres variees chez les patients. Nous examinons certaines de ces constatations et presentons une methode pour mesurer l' amelioration de la lecture labiale en considerant le pourcentage de l' augmentation possible. Les enfants avec surdite prelinguistique qui ont un implant cochleaire sont en mesure de reconnaitre certaines des caracteristiques importantes de la parole, bien que leurs progres soient lents. Les ameliorationsfutures au niveaude la comprehension des signaux et du bruit. du traitement des signaux. de [' optimisation des ajustements des appareils. des interventions chirurgicales et de la readaptation vont contribuer au developpement de ce domaine.

Comparison of Auditory Perception in Cochlear Implanted Children with and without Additional Disabilities
Background: The number of children with cochlear implants who have other difficulties such as attention deficiency and cerebral palsy has increased dramatically. Despite the need for information on the results of cochlear implantation in this group, the available literature is extremely limited. We, therefore, sought to compare the levels of auditory perception in children with cochlear implant...
متن کاملSpeech Perception in Children with Cochlear Implants
Cochlear implants provide access to the speech signal in children with hearing loss that often cannot benefit from acoustic hearing aids. However, despite the numerous positive results in pediatric cochlear implantation, published data still indicated a wide range of performance among implant recipients. Hence, a need to study the possible variables that can affect performance, could account fo...
متن کاملComparison of the high-frequency morpho-syntactic structures of cochlear implant children and children with normal hearing aged 4-6 years
Introduction: Children with cochlear implants experience problems at all language domains, and have more problems in morpho-syntactic skills than others domains. Considering the importance of morphology and syntax in developing of communication skills of children, this study compared the use of high-frequency morpho-syntactic structures among 4-6 years old children with cochlear implants and ty...
متن کاملStudy and Comparison of Formant Characteristics of Persian Vowels in 4-7-year-old Children Using Cochlear Implants and Those Using Hearing Aids
Background and Objective: One of the most important physical properties of vowels is their formant structure. One of the most obvious speech errors in hearing-impaired children is vowel errors. The present study aimed to determine and compare the formant structure of Persian vowels in deaf and cochlear implant children in the age range of 4-7 years. Materials and Methods: This descriptive-anal...
متن کاملCorrelation between Auditory Spectral Resolution and Speech Perception in Children with Cochlear Implants
Background: Variability in speech performance is a major concern for children with cochlear implants (CIs). Spectral resolution is an important acoustic component in speech perception. Considerable variability and limitations of spectral resolution in children with CIs may lead to individual differences in speech performance. The aim of this study was to assess the correlation between auditory ...
