“…When outcomes of cochlear implantation in adults older than 60 years were analyzed, post-cochlear implantation hearing-in noise test (CI HINT) scores were significantly improved after the operation. Individuals with higher pre-CI HINT scores had significantly greater post-CI HINT score improvement (40-60%) than those with lower pre-CI HINT scores (<40% improvement) after adjusting for age at hearing loss onset (7). The same study also showed that the gain in speech scores was negatively affected as the time interval between the hearing loss onset and the timing of cochlear implantation.…”

“…The high rates of long-term CI use in older adults are consistent with the findings from previous studies demonstrating improved speech perception abilities and better health-related quality of life after CI in this population. 15,[19][20][21] We found that earlier age at implantation was associated with a greater rate of regular CI use. These results are consistent with earlier data from our research group demonstrating that earlier intervention was also associated with greater speech perception scores after CI in older adults.…”

INTRODUCTIONHearing loss is prevalent in one in three people over the age of 50, and two-thirds of those older than 70 years. 1 Hearing loss in older adults impairs verbal communication, contributes to social isolation, 2 and has been independently associated with poorer cognitive functioning [3][4][5] and incident dementia. [6][7] While hearing aids improve audibility for most individuals with mild to moderate hearing loss, those who suffer from severe to profound hearing loss generally may acquire greater benefit from electrical hearing provided by a cochlear implant (CI). 8 Currently, the number of older adults in the United States who would potentially meet audiologic criteria for a CI is approximately 150,000, 1 but less than 5% of these older adults are likely to have received a CI System. 9 Many factors could potentially account for the low rate of CI use in older adults, such as a general perception of hearing loss being an inconsequential part of aging and poor awareness of and access to cochlear implantation. Additionally, there are concerns about whether older adults could practically benefit from CI on a daily basis. Older adults can consistently acquire improved speech perception scores after CI in the clinical setting, 10 but patterns of CI use by older adults has received little review. Previous studies have reported results only in small cohorts of older adults with limited durations of follow-up. [11][12][13][14][15][16][17][18] The purpose of our study was to investigate long-term rates of CI use in a consecutive case series of older adults (≥60 years) who received their first CI from 1999-2011. MATERIALS AND METHODS STUDY COHORTWe queried the Johns Hopkins Listening Center database to retrieve all patients ≥ 60 years who received a first CI from 1999 to June 2011 (n = 447). The purpose of this study was to investigate rates of CI use in older adults which is generally defined by the United Nations as adults ≥ 60 years. 33 Of these patients, we were able to successfully obtain follow-up information from the patient or a proxy respondent for 397 individuals (89%) from June to August 2012, and these individuals comprise our analytic cohort. Characteristics of "responders" (n = 397) and "non-responders" (n = 50) did not differ significantly by age of implantation, onset of hearing loss, side of implantation, or manufacturer (data not shown). Non-responders were more likely to have been implanted earlier in the study time period than responders (p < .001). Of the 50 non-responders, 27 (54%) had died based on Social Security Death Index records. For these deceased non-responders, we were unable to obtain proxy information on their CI use at the time of death due to unavailable contact information for surviving family members. This study was approved by Johns Hopkins Institutional Review Board. DATA COLLECTION ON CI USEAs part of a quality assurance initiative at the Johns Hopkins Listening Center, we contacted all CI patients and their families to survey their daily CI use.

“…Individuals with higher pre-CI speech scores had significantly greater post-CI than those with lower pre-CI speech scores after adjusting for age at CI and age at hearing loss onset. In the future, research of CI in older patients should expand its evaluations to take into account the broad cognitive, social and physical outcomes that are likely detrimentally impacted by hearing loss [14].…”

Introduction: Dizziness is very prevalent and makes a great impact on people's life. Because of anatomical and functional similarities of hearing and vestibular systems, it is noted that there is a big relation between hearing loss and vestibular disorders. Depending on the age onset of hearing loss, it can cause even delay on motor development. Objective: To find literature that demonstrates the relation between hearing and balance. Confirming that hearing loss or even intervention to improve quality of hearing can interfere on vestibular system. Methodology: Revision of literature was carried out, preferring recent research only in English. Conclusion: Cochlea and vestibular systems have a close relationship; changes in one of them can cause big damage in the other. So, a complete evaluation of vestibular system is recommended before ear surgeries. Video Head Impulse Test is a new procedure able to evaluate high frequency movements of the head. It was an additional exam of vestibular status and came to help detect problems that were not diagnosed before. Efforts must be directed in order to protect the balance.
