Introduction: A group of researchers conducted a survey on the benefits of cochlear implant (CI) compared to hearing aid (HA). The authors concluded that the CI provided the patients with hearing deficiency (HD) postlingual superior performance when compared to hearing aid users, in addition to better quality of life. In Brazil we have some satisfaction evaluating surveys, among them we can mention the HHIE (hearing inventory for the elderly) and the HHIA (hearing handicap inventory for the adults). For the World Health Organization (WHO) quality of life is the individual's perception of their position in life within the context of the culture and values (WHOQOL Group, 1994) systems.
