“…Although the subjects’ biases were inevitable among different intervals, the results had definite meanings. In this report, at 1 and 3 months post-CI, the percent fail rates of cVEMP and oVEMP were higher than those of a recent report that showed that 19.2% of patients in cVEMP and 17.4% in oVEMP had post-operative function loss at 1–3 months after HP surgery ( Sosna-Duranowska et al, 2021 ). Regarding the vHIT results 4–6 months post-operatively, a similar difference was observed.…”

“…Although 23.61% of our patients used counter electrodes and four recipients implanted with the Nurotron CS-10A electrode, other protective techniques were used. Only one or two evaluation time points were analyzed in a few previous studies on vestibular function protection with soft surgery ( Guan et al, 2021 ; Sosna-Duranowska et al, 2021 ; Tsukada and Usami, 2021 ). The variation in vestibular function at different follow-ups during the first year was analyzed in this study for the first time.…”

“… Tsukada and Usami (2021) found that the risk of vestibular damage could be reduced through less traumatic surgical techniques, such as a RW approach and flexible electrodes. Sosna-Duranowska found that the RW approach in HP techniques was associated with vestibular function protection ( Sosna-Duranowska et al, 2021 ). Other studies have demonstrated that vestibular function can be seriously damaged, even with a RW approach ( Li and Gong, 2020 ; Boje Rasmussen et al, 2021 ).…”

BackgroundCochlear implantation (CI) is an effective and successful method of treating individuals with severe-to-profound sensorineural hearing loss (SNHL). Coupled with it’s great clinical effectiveness, there is a risk of vestibular damage. With recent advances in surgical approach, modified electrode arrays and other surgical techniques, the potential of hearing preservation (HP) has emerged, in order to preserve the inner ear function. These techniques may also lead to less vestibular damage. However, a systematic study on this at different follow-ups after CI surgery has not been documented before.AimsTo investigate changes of vestibular function systematically in recipients at short and long follow-ups after a minimally invasive CI surgery.MethodsIn this retrospective study, 72 patients (72 ears) with minimally invasive CI were recruited. All participants selected had bilateral SNHL and pre-operative residual hearing (RH) and underwent unilateral CI. They were treated to comprehensive care. All patients underwent vestibular function tests 5 days prior to CI. During the post-operative period, follow-up tests were performed at 1, 3, 6, 9, and 12 months. The contemporaneous results of caloric, cervical vestibular-evoked myogenic potential (cVEMP), ocular vestibular-evoked myogenic potential (oVEMP), and video head impulse (vHIT) tests were followed together longitudinally.ResultsOn the implanted side, the percent fail rate of caloric test was significantly higher than that of vHIT at 1, 3, and 9 months post-operatively (p < 0.05); the percent fail rate of oVEMP was higher than vHIT of superior semicircular canal (SSC), posterior semicircular canal (PSC), or horizontal semicircular canal (HSC) at 1, 3, and 9 months (p < 0.05); at 3 and 9 months, the percent fail rate of cVEMP was higher than that of SSC and PSC (p < 0.05). There were no significant differences in the percent fail rates among all tests at 6 and 12 months post-CI (p > 0.05). The percent fail rates showed decreased trends in caloric (p = 0.319) and HSC tested by vHIT (p = 0.328) from 1–3 to 6–12 months post-operatively. There was no significant difference in cVEMP between 1–3 and 6–12 months (p = 0.597). No significant differences on percent fail rates of cVEMP and oVEMP between short- and long-terms post-CI were found in the same subjects (p > 0.05). Before surgery, the abnormal cVEMP and oVEMP response rates were both lower in patients with enlarged vestibular aqueduct (EVA) than patients with a normal cochlea (p = 0.001, 0.018, respectively).ConclusionThe short- and long-term impacts on the vestibular function from minimally invasive CI surgery was explored. Most of the vestibular functions can be preserved with no damage discrepancy among the otolith and three semicircular canal functions at 12 months post-CI. Interestingly, a similar pattern of changes in vestibular function was found during the early and the later stages of recovery after surgery.

“…For patients who suffer from hearing loss after an episode of SSNHL, cochlear implantation may be the only opportunity, due to the possible ossification of the cochlea-especially after viral infections [20][21][22][23]. As far as diagnostics of moderate to profound sensorineural hearing loss (MPSHL), the use of cVEMPs (cervical vestibular-evoked myogenic potentials) to identify and intervene promptly in cases of vestibular disorders, which could endanger the process of integration of the critical sensory stimuli for correct posture and locomotion [24,25]. Additionally, the evidence for viral involvement in SSNHL, Ménière's disease, and vestibular neuritis is indirect and equivocal [26,27].…”

(1) Background: A retrospective clinical study was conducted to compare the effectiveness of different pharmacological and non-pharmacological regimens for treating sudden sensorineural hearing loss (SSNHL). (2) Methods: Adult patients (n = 130) diagnosed with sudden sensorineural hearing loss (SSNHL) and hospitalized between 2015 and 2020 were enrolled in this study. Depending on the treatment regimen applied, patients were divided into five groups. Inclusion criteria were as follows: (i) hearing loss of sudden onset; (ii) hearing loss of at least 30 dB at three consecutive frequencies; (iii) unilateral hearing loss; (iv) age above 18 years. Exclusion criteria were as follows: (i) no follow-up audiogram; (ii) bilateral hearing loss; (iii) recognized alternative diagnosis such as tumor, disorder of inner ear fluids, infection or inflammation, autoimmune disease, malformation, hematological disease, dialysis-dependent renal failure, postdural puncture syndrome, gene-related syndrome, mitochondrial disease; and (iv) age below 18 years. (3) Results: Complete recovery was found in 14% of patients (18/130) and marked improvement was found in 6% (8/130), giving an overall success rate of 20%. The best results were obtained in the second group (i.e., patients given intratympanic glucocorticoid + prolonged orally administered glucocorticoid) where the success rate was 28%. In general, the older the patient, the smaller the improvement in hearing, a correlation that was statistically significant. (4) Conclusions: In treating SSNHL, the highest rate of hearing recovery—28%—was in the group of patients given intratympanic corticoid plus prolonged treatment with orally administered glucocorticoid.

“…Currently, there is no definite conclusion on the time of vestibular function evaluation after cochlear implantation. In some studies on vestibular function changes after cochlear implantation, the time of vestibular function evaluation varies from 1 month to 12 months after surgery ( 18 , 94 – 96 ). Long-term follow-up is available to observe the long-term effects of cochlear implantation on vestibular function in children.…”

Vestibular function in children with cochlear implant: Impact and evaluation

et al. 2022

View full text Add to dashboard Cite

Over the last 30 years, cochlear implant (CI) has been dedicated to improving the rehabilitation of hearing impairments. However, CI has shown potential detrimental effects on vestibular function. For children, due to atypical symptoms and difficulty in cooperating with vestibular function tests, systematic and objective assessments of vestibular function with CI have been conducted sparsely. This review focuses on the impact of vestibular function in children with CI and summarized the evaluation of vestibular function in children. In addition, some recommended strategies are summarized and proposed.
