PURPOSE: to subjectively evaluate the satisfaction degree of users as for the open fit hearing aids (OTE). METHODS: 11 subjects with neurossensorial hearing impairment, with mild to severe degree, with downward sloping, users of OTE, was applied to the self-assessment International Outcome Inventory for Hearing Aids - (IOI-HA - Portuguese version). RESULTS: in the seven assessed domains, it was found that the average for the daily use was 4.45, and the benefit was 4.27, And when compared to residual activity limitation it was 4.45, the satisfaction level 4.72, the residual participation restriction was 4.81, for the impact on others 4.90 and 4.18 for quality of life. It is noteworthy to stress out that the maximum score for each evaluated area was 5.0 and 1.0 as minimum. The average factor for the total score (sum of all questions) was 31.81 and the maximum 35.0. Comparing the factors, we found a statistical significance in Factor 2 over Factor 1. CONCLUSION: with this study we can demonstrate the high satisfaction degree in using HA OTE submitted by the majority of the sample collected in all analyzed domains.
