Abstract:

Abstract Introduction The aim of this study was to determine the impact that the cochlear implant ( CI ) had in the working life of individuals implanted , using the first version of a questionnaire developed in the cochlear implant program at the University Clinic of Navarre . Its purpose was to demonstrate that the CI significantly affected the working lives of these patients . Material and methods This was a retrospection study on a population of 60 patients ( mean age , 48 years old ) with bilateral profound sensorineural hearing loss treated with CI and to whom a questionnaire on working life satisfaction was given . Results Of the patients completing the questionnaire , 94 .23% were currently satisfied at work . Almost all of them ( 93 .05% ) were more motivated to go to work after the implantation . The majority ( 79 .31% ) considered themselves more competent after surgery and device activation . Social relations at work were considered to have improved after cochlear implantation by 67 .23% of patients . Conclusions The CI provided positive support in the professional sphere as well as in social abilities by improving communication skills of implanted patients . The development of tools to assess the degree of job satisfaction of patients treated with a CI is of great interest .
