Abstract

A computerized search of MEDLINE 1966-March 2004 was performed. The term “cochlear implant” (CI) was exploded and the resulting articles were limited to adults, yielding 1246 studies. These articles were then reviewed to identify those that met the following inclusion criteria: 1) cochlear implantation with multichannel CIs, 2) use of standardized tools to measure speech recognition outcomes, 3) follow-up period ≥6 months. Exclusion criteria used were: 1) patient age <18 years at cochlear implantation, 2) patient age <3 years at onset of severeprofound deafness, 3) study performed before 1985. The bibliographies of the articles that met these inclusion criteria were manually checked to ensure no further relevant articles could be identified. This process yielded four reports of randomized controlled trials (RCTs). Two of these publications reported longer-term results on the same patients in the initial two trials (VA Clinical Trial, Iowa Clinical Trial), so only the longer-term results are presented here.
