Objective: Evaluate the impact of quality of life in the functional result audiologic in patients implanted with system BAHA®. Material and methods: The study included 19 patients implanted with BAHA percutaneous and transcutaneous system in its varieties BP100, BP110, BAHA4 and BAHA5. To measure the quality of life, the Glasgow Benefit Inventory was used. The audiological result was performed with pure tone audiometry at frequencies 500, 1000, 2000 and 3000Hz. Before and after the implant. Applying the tests: Student's T for related samples, Spearman, Chi 2 Results: The change in the degree of hearing loss was significant in the 3 cases with moderate-severe hearing loss, 100% changed to mild; 12 with severe hearing loss, 9 (75.0%) were mild and 3 (25.0%) were normal; 4 cases with profound hearing loss 3 (75.0%) were mild and 1 (25.0%) were normal (p = 0.0001, chi square). The pure tone averages decreased 45.7% the bone-to-air GAP was reduced by 57.5%. There was no significant relationship between the degree of post-operative hearing, the etiology or type of hearing loss and the quality of life. Postoperative pure tones correlated positively with the dimensions of the Glasgow quality of life scale. Conclusions: Our study demonstrates a high audiometric gain similar with different implant systems BAHA, which is compatible with significant improvement in quality of life of patients.
