Age-related use and benefit of the bone-anchored hearing aid compact.

Abstract

OBJECTIVE: To study age-related patient satisfaction with the bone-anchored hearing aid (BAHA) compact. METHODS: A retrospective postal questionnaire, the International Outcome Inventory for Hearing Aids (IOI-HA), was sent to 211 BAHA Compact users. Questionnaire responses from 135 BAHA users were analyzed related to age, sex, years of BAHA experience, and the hearing thresholds (pure-tone average) at the aided side. Age ranged from 18 to 77 years. RESULTS: The IOI-HA showed that the BAHA Compact was greatly appreciated by almost all of the users: most patients stated that they were using the device for most of the day; it helped them to hear better and it reduced the number of situations in which hearing impairment was problematical. The cumulative score on the questionnaire was negatively influenced by age (rho = -0.191, p = 0.05). Furthermore, increase in sensorineural hearing loss (SNHL) component was associated with decrease in total IOI-HA scores (Spearman rho = -0.193, p < 0.05). A significant correlation was found between age and the SNHL component (Spearman rho = 0.525, p < 0.001).There were no significant differences in the levels of difficulty with placing the BAHA on the implant or with handling the BAHA between the age groups. Cleaning the skin around the implant causes the most difficulties in the youngest age group (p < 0.02). CONCLUSION: The BAHA Compact enhances participation in various domains of communication. Differences in patients' satisfaction seemed to be correlated with the SNHL component rather than age.
