Purpose The decline of sensory systems during aging has been widely investigated and several papers have correlated the visual, hearing and vestibular systems and the consequences of their functional degeneration. Hearing loss and presbyvestibulopathy have been found to be positively correlated as is with the risk-to-fall. Material and methods The present study was therefore designed as systematic review (due to PRISMA criteria) which should correlate hearing amplification by hearing aids and/or cochlear implants with balance outcome. However, the literature review (Cochrane, PubMed) revealed ten paper (prospective, controlled trials and acute trials) with heterogenous patient popiulations and non-uniform outcome measures (i.e., gait analysis, questionnaires, postural stabilometry) so that no quantitative, statistical analysis could be performed. Results The qualitative analysis oft he identified studies showed that hearing amplification in the elderly improves spatio-temporal orientation (particularly with cochlear implants) and that the process of utilizing auditory information for balance control takes some time (i.e., the neuroplasticity-based, learning processes), usually some months in cochlear implantees. Discussion Hearing and balance function degenerate independently from each other and large interindividual differences require a separate neurotological examination of each patient. However, hearing amplification is most helpful to improve postural stability, particularly in the elderly. Future research should focus on controlled, prospective clinical trials where a standardized test battery covering the audiological and neurotological profile of each elderly patient pre/post prescription of hearing aids and/or cochlear implantation should be followed up (for at least 1 year) so that also the balance improvements and the risk-to-fall can be reliably assessed (e.g., by mobile posturography and standardized questionnaires, e.g., the DHI).

ZusammenfassungEs mehren sich zunehmend Hinweise, dass neben visuellen, vestibulären und somatosensorischen Afferenzen auch das Hören eine Rolle bei der Regulation des Gleichgewichts einnimmt. So scheint, insbesondere im Alter, ein progredienter Hörverlust auch mit einer Abnahme der Stabilität einherzugehen. Mehrere Studien untersuchten diesen Zusammenhang bei Normalhörenden, bei Patienten mit konventionellen Hörgeräten sowie nach Versorgung mit implantierbaren Hörsystemen wie auch bei Patienten mit vestibulären Störungen. Trotz der inhomogenen Datenlage und fehlenden Evidenz scheint das Hören mit dem Gleichgewichtsystem zu interagieren mit dem Potential, stabilisierend zu wirken. Es konnten darüber hinaus Erkenntnisse hinsichtlich audiovestibulärer Interaktionsmechanismen gewonnen werden, welche möglicherweise zukünftig in therapeutische Aspekte bei vestibulären Erkrankungen einfließen könnten. Es sind jedoch weitere prospektive kontrollierte Studien erforderlich, um diese Fragestellung auf evidenzbasiertes Niveau zu führen.

“…Regarding reports of pre-existing symptoms, the majority of articles did not mention them, however, about post symptoms, 17 cited vertigo as the main symptom ( 9 , 14 – 16 , 21 , 25 , 26 , 28 , 30 , 33 , 39 , 40 , 44 , 48 , 50 – 52 ), and in 5 of these ( 25 , 26 , 28 , 30 , 39 , 51 ), the round window was the surgical intervention, 5 ( 16 , 21 , 33 , 40 , 44 ) had cochleostomy, in 1 ( 25 ) both interventions were present, and the others did not mention the surgery, despite having reported the symptoms. Of all the articles eligible for this review, 44.7% ( 9 , 14 – 16 , 21 , 25 , 26 , 28 , 30 , 33 , 39 , 40 , 44 , 48 , 50 – 52 ) reported vertigo as a post-implantation symptom, followed by dizziness and imbalance ( 16 , 29 , 32 , 35 , 36 , 38 , 39 , 44 , 45 , 48 , 50 , 51 , 53 ); however, in 7.8% ( 34 , 54 , 55 ) of the studies, there were no reports or citations of any referred symptom ( Supplementary Table 1 ).…”

IssueThe findings in literature indicate inconsistency in the complications caused by the implant of electrodes in the cochlea; vestibular alterations and balance disorders are mentioned as the most likely.PurposeTo evaluate, in literature, through the results of multiple vestibular function tests, the effects of cochlear implant surgery on postural stability in adult patients and to analyze.HypothesisFrom the PICO strategy, where the Population focuses on adults, Intervention is cochlear implant surgery, Comparisons are between implanted patients, and Outcomes are the results of the assessment of cochlear function, the research question was formulated: Are there deficits in vestibular function in adults undergoing cochlear implant placement?MethodSystematic review based on cohort, case–control, and cross-sectional observational studies. Information sources: Databases between 1980 and 2021, namely, PubMed, Cinahl, Web Of Science, Cochrane, and Scopus. Search strategy using Mesh terms: “Adult,” “Cochlear Implant,” “Postural Balance,” “Posturography,” “Cochlear Implant,” “Dizziness,” “Vertigo,” “Vestibular Functional Tests,”and “Caloric Tests.” Populational inclusion criteria: studies with adult patients; intervention: cochlear implant placement surgery; comparison: analysis of a vestibular function with vestibular test results and pre- and postoperative symptoms; outcome: studies with at least one of the vestibular function tests, such as computerized vectoelectronystagmography (VENG), vestibular-evoked myogenic potentials (VEMPs), caloric test, video head impulse test (VHIT), head impulse test (HIT), videonystagmography, (VNG) and static and dynamic posturography. Exclusion criteria: studies without records of pre- and postoperative data collection and studies with populations under 18 years of age. Screening based on the reading of abstracts and titles was performed independently by two reviewers. In the end, with the intermediation of a third reviewer, manuscripts were included. Risk of bias analysis, performed by two other authors, occurred using the JBI “Critical Appraisal Checklist.”ResultsOf the 757 studies, 38 articles met the inclusion criteria. VEMP was the most commonly used test by the studies (44.7%), followed by the caloric test (36.8%) and vHIT (23.6%). Most studies performed more than one test to assess vestibular function.ConclusionAmong all vestibular tests investigated, the deleterious effects on vestibular function after cochlear implant surgery were detected with statistical significance (P < 0.05) using VEMP and caloric test. Comparing abnormal and normal results after implant surgery, the vestibular apparatus was evaluated as having abnormal results after cochlear implant surgery only in the VEMP test. The other tests analyzed maintained a percentage mostly considered normal results.Systematic review registrationidentifier: CRD42020198872.
