title: Prognosticating speech performance in multichannel cochlear implant patients.
abstract: Twenty patients received multichannel cochlear implants between April 1984 and May 1986 at the University of Utah Medical Center. All patients have been followed for at least 1 year postimplant. Preimplant screening included audiometric testing, electronystagmogram (ENG), promontory stimulation, computed tomography (CT) scanning, and psychological evaluation. Based on postimplant audio-only CID sentence discrimination scores, these patients were divided into three groups: good (CID greater than 79%), intermediate (CID, 21% to 79%), and poor (CID less than 21%). Preimplant factors that correlated with CID scores were hearing loss duration, previous use of hearing aids, lip-reading ability, tinnitus, positive ENG calorics, preimplant pure-tone average, promontory stimulation threshold, and understanding of the project. Only previous hearing aid usage approached statistical significance (p = 0.05). A larger patient sample is needed to verify these results.
