title: [Long-latency evoked acoustic potentials in patients with cochlear implants compared with normally hearing subjects].
abstract: Electrically evoked long-latency acoustic potentials (eLLAP) are used to objectivize adjustment of the speech processor. eLLAP components can be useful in detecting electric stimuli and discriminating between changes in the topography of electrical stimulation. Electrically evoked long-latency acoustic potentials in patients with cochlear implants are different from those of normally hearing subjects in that they reflect specific pathophysiological features of their hearing system. The basal region of the cochlea is the main contributor to the difference between eLLAP in the patients and healthy subjects. The difference tends to be levelled during the very first adjustment of the speech processor. The degree of leveling depends on the cochlear region and is highest with respect to the stimulus detection mechanism.
