Cochlear Implant Surgery

Over the last decade, cochlear implantation has become an increasingly viable alternative for the treatment of profound sensorineural hearing loss in children. Although speech and hearing professionals play an important role in the communicative, social, and academic development of children with cochlear implants, many may be unfamiliar with recent advances in implant technology. This article provides an overview of the components of cochlear implant systems and the speech processing strategies that are currently being used by toddlers, preschoolers, and school-age children. A brief description of cochlear implant surgery and the procedures for programming these devices are also included. Finally, information regarding the use of assistive listening technology in the classroom is presented.

Objetivo: Comparar los diferentes grados del trauma en las estructuras anatómicas intracocleares luego de la inserción de tres diferentes electrodos perimodeolares insertados con dos tamaños diferentes de cocleostomías. Trauma valorado fluoroscópicamente y anatómico microscópico. Diseño del estudio. Estudio experimental con dos variables. Métodos. Se realizaron cocleostomías de 1.3 y 2 mm en 15 huesos temporales de cadáver, estos fueron implantados bajo visión fluoroscopia con uno de los siguientes electrodos perimodeolares: electrodo Nucleus 24 contur (Cochlear Implant System), electrodo Hi Focus Helix (Advanced Bionics), electrodo Combi 40 + (Medel). Se efectúan microcortes en 15 cócleas con el electrodo inserto, teniendo 3 cócleas como grupo control sin implantar. Cada cóclea fue analizada con otomicroscopio a un aumento 16x, valorando cualquier posible trauma durante la inserción. Resultados: Se encontraron tres diferentes grados de alteraciones observadas durante la inserción, en algunas fue solamente observada en la visión fluoroscópica; así mismo no se encontraron diferencias estadísticamente significativas entre el tipo de electrodo y el tamaño de la colostomía. Conclusiones: La inserción de los electrodos perimodeolares crean diferentes grados de trauma histomorfológicos en la cóclea; sin embargo, este modelo aunque es efectivo no es el óptimo para documentar los grados de lesión coclear. La visión fluoroscópica de la inserción puede proveer una ubicación inicial adecuada del lugar de la lesión. Al parecer no hay una relación directa entre lo observado fluoroscópicamente y los hallazgos anatómicos cocleares luego de analizar los microcortes. Significancia clínica del estudio: El implante in vitro de huesos temporales bajo visión fluoroscópica es una poderosa herramienta académica para el entrenamiento de cirujanos en el campo de la otología.

Speech Information

Since 1979, the Australian speech-processing strategy has been based on the presentation of an estimate of F2 coded by electrode position and F0 coded by pulse rate. Although providing limited information, this strategy has produced good results with significant hearing-alone performance. This paper describes a number of strategies that provide further speech information in an attempt to increase hearing-alone performance to a level where the cochlear implant is able to operate in its own right rather than as an adjunct to lipreading. The strategies are all based on the addition of F1 to the existing strategy. Both electrode and temporal coding of F1 is described, and the performance and percepts produced are discussed. Amplitudes of the two formants must be carefully controlled to avoid masking. The implications of the strategies on the design of hardware are described.
