Quality of life in postlingually deaf patients following cochlear implantation

Most cochlear implant studies are focused on improvement of speech perception associated with implantation. The goal of this study was to assess the impact of cochlear implantation on quality of life changes in Spanish users. Thirty postlingually deaf patients fitted with a cochlear implant completed the Glasgow Benefit Inventory, a questionnaire dealing with communication abilities, and an open-ended questionnaire. The Glasgow Benefit Inventory revealed a positive effect in 93% of patients. The use of a cochlear implant significantly enhanced discrimination ability, telephone use and self-confidence. A high degree of satisfaction was achieved in all situations except with background noise. Ninety-six percent of patients would recommend the operation to a friend. A dramatic improvement in quality of life following cochlear implantation is revealed by a great majority of patients. The results cannot only be explained by enhancements to auditory perception.
