Cochlear implant in incomplete partition type I
In this investigation, we report on 4 patients affected by incomplete partition type I submitted to cochlear implant at our institutions. Preoperative, surgical, mapping and follow-up issues as well as results in cases with this complex malformation are described. The cases reported in the present study confirm that cochlear implantation in patients with incomplete partition type I may be chall...
متن کاملA model cochlear partition involving longitudinal elasticity.
This paper addresses the issue of longitudinal stiffness within the cochlea. A one-dimensional model of the cochlear partition is presented in which the resonant sections are coupled by longitudinal elastic elements. These elements functionally represent the aggregate mechanical effect of the connective tissue that spans the length of the organ of Corti. With the plate-like morphology of the co...
متن کاملPhase of Shear Vibrations within Cochlear Partition Leads to Activation of the Cochlear Amplifier
Since Georg von Bekesy laid out the place theory of the hearing, researchers have been working to understand the remarkable properties of mammalian hearing. Because access to the cochlea is restricted in live animals, and important aspects of hearing are destroyed in dead ones, models play a key role in interpreting local measurements. Wentzel-Kramers-Brillouin (WKB) models are attractive becau...
متن کاملParents' views on changing communication after cochlear implantation.
We sent questionnaires to families of all 288 children who had received cochlear implants at one center in the United Kingdom at least 5 years previously. Thus, it was a large, unselected group. We received 142 replies and 119 indicated that the child and family had changed their communication approach following cochlear implantation. In 113 cases the change was toward spoken language and in 6 ...
متن کاملImplementation of Spectral Maxima Sound processing for cochlear implants by using Bark scale Frequency band partition
A new method on the basis of Bark scale frequency-band partition was presented to improve the recognition performance of cochlear implants. In the nature of physics, it consists with human’s cochlea filter properties. Also the mechanism of a cochlear implant and its spectral maxima sound processing (SMSP) strategy were presented. The time -frequency analyzing property of human's cochlea was ana...
