RESUMEN

INTRODUCTION: Active aging emphasizes optimizing health and participation for a better quality of life as people age. This paper explores the significant impact of hearing loss and balance disorders on the elderly. Age-related hearing loss is thought to contribute to communication breakdown and cognitive dysfunctions. The "hearing and balance in healthy aging" project focuses on early detection, mitigation, and advocacy. Objectives include exploring epidemiological traits, evaluating overall well-being impact, proving positive intervention effects, and advocating societal care for the elderly with hearing loss and balance disorders, aiming to reduce their broader impact on cognition, independence, and sociability. METHODS: This study is observational, prospective study. Subjects over 55 years old with a follow-up every year or every 2 years were divided into three groups, according to their hearing and balance: within the normal range (group A), detected and not treated (group B), and detected and treated (group C). At each visit, they underwent a series of tests or questionnaires, evaluating different areas: hearing, balance, cognition, depression, dependence, tinnitus, loneliness, health. RESULTS: A total of 710 patients were included in the study. The distribution of patients was as follows: group A - 210 patients, group B - 302 patients, and group C - 198 patients. Significant differences were found between the three groups related to age, sex, educational level, bilingualism, and work activity. In group C, there was a higher percentage of males, older than in groups A and B, and the percentage of individuals with a university education was lower (28%), as was the rate of bilingualism (23%). In terms of hearing, significant differences were found in the three groups in the mean PTA, speech discrimination in quiet, and the HINT test, with worse results for group C. Only patients in group C presented a perception of hearing impairment, and the handicap caused by hearing impairment worsened from group A to C. Concerning balance, both tests performed (TuGT and DHI) revealed increased difficulty in maintaining autonomous walking from group A to C, which, again, exhibited the worst results, with statistically significant differences across the group. Analysis about cognition revealed significant differences in DSST questionnaires and in TMT scores, where group C had the worst scores. In HUI3 questionnaire scores, the differences between each and every group were statistically significant, with group C showing moderate disability. CONCLUSION: This extensive analysis, encompassing a considerable number of subjects, reveals significant findings that have important implications for the early prevention of hearing loss and its consequent consequences. At the same time, these data represent an initial exploration, which raises the need for in-depth examinations of additional factors and longer follow-up to continue contributing insights and knowledge for a healthy aging.

RESUMEN

INTRODUCTION: Bone conduction implants have been indicated for patients with conductive hearing loss, mixed hearing loss, and even profound unilateral sensorineural hearing loss. With the introduction of Bonebridge®, new transcutaneous implant options emerged. The latest is Osia®, a direct-drive variant or active systems where the implant directly generates and applies vibration to the bone. MATERIALS AND METHODS: Retrospective study of two cohorts of patients treated with active bone conduction implants at a single center, one with the Bonebridge® device and the other with Osia®. OUTCOMES: Fourteen patients were included, seven in each group (n=14). The Bonebridge® group showed an average hearing gain in tonal intelligibility thresholds of 32.43±21.39 dB and a gain in the average intelligibility threshold (with 50% discrimination) of 26.29±19.10 dB. In the Osia® group, there was a gain in average tonal thresholds of 41.49±14.16 dB and 23.72±6.98 dB in average intelligibility thresholds. Both devices contributed to improvements in patients' quality of life, as assessed with APHAB in all the variables studied in the test. Both devices offer rehabilitation for hearing loss as an alternative to hearing aids. The Osia® system shows statistically significant(p<0.05) improvements in mid and high frequencies, but Bonebridge® slightly outperforms in speech understanding at 50%. Differences in average tonal thresholds and quality of life are not statistically significant. CONCLUSIONS: While auditory improvement is observed post-implantation, other aspects, such as intelligibility thresholds and quality of life, lack statistical significance. Given the limited experience with Osia® and the small sample size, the choice of the device should be personalized. Although the literature is inconsistent due to small sample sizes and variable approaches, some studies suggest potential advantages of the Osia® system, especially in speech comprehension in different environments and greater hearing gain compared to Bonebridge®.

RESUMEN

UNLABELLED: Brainstem Auditory Evoked Potentials are considered exogenous potentials, that is, the responses obtained are highly dependent upon the characteristic of the stimulus used to evoke them. AIM: To investigate the influence of the click stimulus polarity in the study of Brainstem Evoked Response Audiometry (BERA) at different intensities, using insertion-canal earphones. TYPE OF STUDY: Clinical. MATERIALS AND METHODS: 33 individuals, aged between 18 and 28, with no auditory alteration were submitted to BERA testing, with click stimulus on the rarefaction, condensation and alternate polarities, in different intensities. RESULTS: The absolute latencies of the V wave proved to be lower in the rarefaction polarity when compared to the others and, at 80 dBnHL, there was a significant difference between rarefaction and the other polarities for interpeak latencies III-V and I-V. There was a high correlation between the condensation and alternating polarities for absolute and interpeak latencies at 80 dBnHL. CONCLUSION: the click stimulus polarity has a significant influence on BERA. In the routine use of the TDH 39 earphone, with alternating polarity, we suggest that condensation polarity is more adequate for standardized comparison purposes, due to the higher similarity of the latencies found in this insertion earphone study.
