Objective

To provide a scoping review of the available literature for determining objectively the effect of cochlear implantation on vestibular function in children.

Methods

A literature search was performed and the following criteria were applied: vestibular tests that were performed on subjects within the range of 0–18 years old before and after cochlear implantation. The papers conducted at least one of the following tests: (video) head impulse test, caloric test, cervical and ocular vestibular evoked myogenic potentials or rotatory chair test. Included papers underwent quality assessment and this was graded by risk of bias and directness of evidence.

Results

Fourteen articles met the selection criteria. The included studies showed that cochlear implantation leads to a decrease in vestibular function in a proportion of the patient population. This loss of vestibular function can be permanent, but (partial) restoration over the course of months to years is possible. The pooling of data determined that the articles varied on multiple factors, such as time of testing pre- and post-operatively, age of implantation, etiologies of hearing loss, used surgical techniques, type of implants and the applied protocols to determine altered responses within vestibular tests. The overall quality of the included literature was deemed as high risk of bias and medium to low level of directness of evidence. Therefore, the data was considered not feasible for systematic analysis.

Conclusion

This review implicates that vestibular function is either unaffected or shows short-term or permanent deterioration after cochlear implantation in children. However, the heterogeneity of the available literature indicates the importance of standardized testing to improve our knowledge of the effect of cochlear implantation on the vestibular function and subsequent developmental consequences for the concerned children.

人工耳蜗植入对儿童前庭功能的影响:范围审查

Objective

对现有文献进行范围审查,以客观地确定人工耳蜗植入对儿童前庭功能的影响。

Methods

进行了文献检索并应用了以下标准:在人工耳蜗植入之前和之后对 0-18 岁范围内的受试者进行的前庭测试。论文至少进行了以下一项测试:(视频)头脉冲测试、热量测试、颈椎和眼前庭诱发肌源性电位或旋转椅测试。纳入的论文进行了质量评估,并根据偏倚风险和证据的直接性进行分级。

Results

十四篇文章符合选择标准。纳入的研究表明,人工耳蜗植入会导致一部分患者的前庭功能下降。这种前庭功能的丧失可能是永久性的,但在数月至数年的过程中(部分)恢复是可能的。数据汇集确定,文章因多种因素而异,例如术前和术后测试时间、植入年龄、听力损失病因、使用的手术技术、植入物类型和应用协议以确定改变的反应前庭测试。纳入文献的总体质量被认为是高偏倚风险和中等至低水平的证据直接性。因此,该数据被认为不适用于系统分析。

Conclusion

该评价表明,儿童植入人工耳蜗后,前庭功能要么不受影响,要么出现短期或永久性恶化。然而,现有文献的异质性表明标准化测试对于提高我们对人工耳蜗植入对相关儿童前庭功能的影响以及随后的发育后果的了解的重要性。
