OBJECTIVE: Analyze the users' satisfaction with their CROS and BICROS hearing aids with wireless technology, and assess the psychosocial effects by means of QI-AASI and HHIA-S questionnaires. METHODOLOGY: Eight patients were surveyed(5 men; age, 18 to 77 years). All participants underwent otorhinolaryngologic evaluation, anamnesis, audiometry, vocalaudiometry, and immittance and QI-AASI and HHIA-S questionnaires. After the questionnaires were completed, either CROS or BICROS adaptation were performed as follows: CROS for patients with unilateral anacusis, and BICROS for patients with unilateral anacusis and a contralateral ear with hearing loss, either mild or deep. Phonak hearing aids were used, including micro-retroauricular CROS and Audéo S Smart III for the contralateral ear. A transmitter microphone captured the sounds from the anacusic ear and transmitted them, in real time and wirelessly, to the receiving apparatus of the ear with better hearing. They wore them for 12 days, but on the fifth day, they were asked to make a phone call to the speech therapist surveying themand use their anacusic ear. At the end of the 12-day period, the HHIA-S and IQ-AASI questionnaires were retaken. RESULTS: There was a statistically significant difference (p<0.000) between the responses obtained from the QI-AASI and HHIA-S questionnaires before and after using the CROS and BICROS hearing aids with wireless technology. There was no significant difference between satisfaction and age. CONCLUSION: The QI-AASI and HHIA-S questionnaires showed that users of the CROS and BICROS hearing aids with wireless technologywere satisfied with the results and received psychosocial benefits.
