OBJECTIVE: To draw a profile of the patients seen in a Grant Program of Auditive Prosthesis of UFSM, analyzing the variables: age, sex, type and degree of hearing loss, number of patients fitted with hearing aids, type of adaptation, unilateral or bilateral ear and adapted. MATERIAL AND METHODS: this is an observational epidemiological descriptive, retrospective, which included data from patients treated between February of 2006 and July of 2010, totaling 1572 files. RESULTS: The ages ranged from three to 100 years, mostly elderly (52.8%), with no significant difference in frequency between the genders. Considering the confidence interval, there are more young adult women and older men attended than estimated. The sensorineural loss (73.12%) and moderate (54.7%) were the most frequent, except in children where the most common was the deep (45.3%). There was a higher number of ears of children, teenagers and elderly with sensorineural hearing loss, conductive and young adults with older middle-aged mixed hearing loss and normal hearing than estimated, as well as the ears of children, teenagers and young adults with loss deeper and older adults with mild and moderate. Prosthesis was more than 99% of patients 258 unilaterally and 1302 bilaterally. CONCLUSION: it is believed that the study provided important information about the epidemiology of hearing and the planning of public health. It was concluded that the program has been showing good results on the number of prosthetization, despite the need for improvements in the speed of the process, technical, human resources and capabilities.
