“…Bonutti further explains that cochlear implant surgery can affect the vestibular system, not only in the implanted ear but also in the non-implanted ear, with post-caloric nystagmus areflexia predominating. However, vestibular symptoms occur in a smaller proportion of affected individuals, and there may even be improvement in vestibular disturbances after cochlear implant surgery ( 19 ). In Imai, CI leads to a slight deterioration of utricular function, but not enough to cause vertigo ( 27 ).…”

“…Due to the different opinions and studies, authors disagree with their findings. Between authors who describe that CI can improve body balance ( 8 , 10 – 12 ), those who believe that CI negatively interferes with vestibular function ( 9 , 13 – 19 ), and authors who maintain that CI has no effect in this regard ( 16 , 20 – 23 ), there are many different studies and evaluation methodologies.…”

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.

Vestibular dysfunction and postural balance in cochlear implant users: a narrative literature review

2018

View full text Add to dashboard Cite

Cochlear implants directly stimulate nerve fibers and ganglion cells of the auditory nerve, which transform sound energy into low levels of electrical current, stimulating the remaining fibers of the auditory nerve in patients with severe to profound hearing loss, in order to provide the significant range of auditory sensation and speech comprehension. Due to the close relationship between cochlea and vestibular receptors, some patients may present vestibular and postural balance changes concomitantly after surgery. This study aimed to perform a narrative review of the main studies that relate vestibular symptoms in patients implanted in the last six years. The research was performed through the databases: SciELO, LILACS and PubMed, using associated descriptors for "cochlear implant", "vestibular dysfunction", "vertigo" and "balance", totalizing 21 studies that fitted the inclusion criteria. The results were described in a chronological order of publication, showing the main conclusions. Of the total studies analyzed, 18 related vestibular function to cochlear implant and only 3 studies did not find such a relationship. The literature characterize the effects of the cochlear implant on the vestibular system, however, the results are contradictory.

“…Os mecanismos envolvidos na melhora da função do labirinto contralateral ainda não são claros, mas a plasticidade do sistema neural pode explicá-los (Ribari et al, 1999;. Bonucci et al (2008) (Migliaccio et al, 2005).…”

“…Podemos atribuir essa melhora ao processo de compensação vestibular, opinião também compartilhada por Buchman et al (2004), Filipo et al (2006), Bonucci et al (2008) e Krause et al (2009a). (Bittar et al, 2007).…”

professor titular do Departamento de Otorrinolaringologia do HCFMUSP, pela oportunidade de poder realizar essa pesquisa. À minha orientadora Prof. Dra. Roseli Saraiva Moreira Bittar que considero uma verdadeira mentora e um exemplo de profissionalismo. Além disso, possui a admirável capacidade de transformar a complexidade em simplicidade e tem o dom de indicar a pessoa certa para o trabalho certo. Foi um privilégio ter tido a oportunidade de estar ao seu lado e aprender sobre esse universo maravilhoso da Otoneurologia durante todos esses anos. Ao meu querido Prof. Riquelme Romero Leal Portela que com muito carinho, me ensinou os primeiros princípios em otorrinolaringologia e que sempre teve muita confiança de que eu iria muito longe nesse caminho do saber. Ao mestre Dr. Plínio Conceição dos Santos pelos seus ensinamentos em anatomia e fisiologia em otorrinolaringologia durante a residência na PUC de Sorocaba. Sempre me incentivando a fazer pesquisa e, sobretudo, a ingressar na vida acadêmica. Ao Dr. Marco Aurélio Bottino, um verdadeiro pai, com quem aprendi mais do que do que otoneurologia. Sempre me incentivando com carinho e amor a seguir em frente. Ao Dr. Luiz Ubirajara Sennes, pelo apoio e coordenação da Pósgraduação.
