“…Children typically start walking around the age of 13 to 14 months (Størvold et al 2013). Reaching this milestone was especially difficult for the group of implanted children in this study, perhaps as a consequence of subtle alterations in vestibular functioning potentially caused by the CI (Tien & Linthicum 2002;Migliaccio et al 2005;Filipo et al 2006;Bonucci et al 2008;Jacot et al 2009;Licameli et al 2009;Wagner et al 2010). Table 2 indicates that only 13 of 21 children of the CI group could walk at the test moment around the age of 18 months, while 14 of 17 children of the control group could walk independently at that test moment.…”

“…A cochlear implant (CI), an accepted rehabilitation device for children with a hearing loss, entails a potential risk for additional vestibular damage (Tien & Linthicum 2002;Migliaccio et al 2005;Filipo et al 2006;Bonucci et al 2008;Jacot et al 2009;Licameli et al 2009;Wagner et al 2010).…”

“…A CI is particularly effective in young children permitting them to acquire effective communication skills (Jacot et al 2009). However, a CI is not without risk to the nearby vestibular canals and otolith organs (Tien & Linthicum 2002;Migliaccio et al 2005;Filipo et al 2006;Bonucci et al 2008;Jacot et al 2009;Licameli et al 2009;Wagner et al 2010).

“…36,NO. 3, have been addressed in the literature: direct surgical trauma to the saccular macula and/or semicircular canals, a postsurgical inflammatory process resulting in fibrosis or loss of hair cells, disruption of the inner ear fluid homeostasis, electrical stimulation of the inferior vestibular nerve, and/or the saccular macula (Tien & Linthicum 2002;Buchman et al 2004;Migliaccio et al 2005;Filipo et al 2006;Handzel et al 2006;Jin et al 2006Jin et al , 2008Bonucci et al 2008;Jacot et al 2009;Licameli et al 2009;Wagner et al 2010). The risk of a vestibular impairment after implantation is likely to be underestimated in children.…”

Examining the Impact of Cochlear Implantation on the Early Gross Motor Development of Children With a Hearing Loss

et al. 2015

View full text Add to dashboard Cite

This study shows that the trajectory of gross motor development can be changed in children with a hearing loss after a cochlear implantation. Implanted children show a drop in their gross motor performance within the age range of 6 to 18 months, at which period the majority of the implantations took place, with a tendency of recovery toward the age of 2 years. However, longer follow-up will be necessary to trace whether the implanted children catch up their motor delay in comparison with nonimplanted children with a hearing loss at later age.

“…Maybe this can be explained by the short postoperative re-test period (2 days) [8]. Unfortunally, was not possible to pool and analyze studies based on follow-up periods because several papers were not specific, either they did not specify the period [15], or provided a very wide range for it [14]. …”

ImportanceVestibular disorders have been reported following cochlear implant (CI) surgery, but the literature shows a wide discrepancy in the reported clinical impact. The aim of this meta-analysis is to quantify the effect of CI before and after surgery on the outcomes of vestibular tests, postural stability, and subjective perception of dizziness.ObjectiveTo evaluate the effects of CI surgery on vestibular function in adult patients (≥18 years) with sensorineural hearing loss who underwent unilateral or bilateral implantation.Data sourcesMEDLINE, PubMed, Web of Science and Cochrane Library from January 1, 1995, through July 12, 2016.Study selectionPublished studies of adult patients who received unilateral or bilateral CIs and whose vestibular function or postural stability was assessed before and after surgery.Data extractionFrom each study, test results before and after surgery were compared, for the following five tests: clinical head impulse test (HIT); bi-thermal caloric irrigation of the horizontal semicircular canal; vestibular evoked myogenic potential (VEMP); dizziness handicap inventory (DHI); and computerized dynamic posturography (CDP).ResultsTwenty-seven studies met all inclusion criteria. Most studies performed either bi-thermal caloric irrigation and/or VEMP, with fewer studies investigating changes in HIT, posturography or DHI. CI surgery significantly affected the results of caloric and VEMP testing. However, HIT results, posturography, and DHI, scores were not significantly affected after CI surgery.Conclusions and relevanceCI surgery has a significant negative effect on the results of caloric as well as VEMP tests. No significant effect of CI surgery was detected in HIT, posturography, or DHI scores. Overall, the clinical effect of CI surgery on the vestibular function was found to be insignificant. Nonetheless, the potential effects of surgery on the vestibular system should be discussed with CI candidates before surgery.

Meta‐analysis of subjective complaints of vertigo and vestibular tests after cochlear implantation

et al. 2018

View full text Add to dashboard Cite

Cochlear implantation has a significant impact on subjective vertigo and vestibular receptor function. This is affected by the patient's age at the time of surgery. The surgical technique (round window or cochleostomy) may influence the outcome, but this requires further investigation. Younger patients may compensate better following vestibular dysfunction. Perioperative testing is required to correlate vestibular impairment and subjective complaints. Laryngoscope, 2018 Laryngoscope, 128:2110-2123, 2018.

Vestibular function in cochlear implant users

Abstract: the study showed that cochlear implant surgeries could injure the vestibular system in both ears. However, the vestibular symptoms take place in a smaller proportion, and can improve after cochlear implant surgery.
