The changes in the inner ear affect both the cochlea and the vestibule and these effects are observed after cochlear implantation surgery. The aim of the current study is to evaluate the effect of unilateral cochlear implant use on vestibulo-ocular reflex (VOR) in children.
In the current study, 29 cochlear implanted children, aged 7-18 years, were include as the study group and 32 children, in the same age range, were included with normal-hearing as the control group. vHIT was used to evaluate VOR and the results of unilateral CI users were compared with the control group. The study group was evaluated in two different situations: cochlear implant sound processor on (CI-ON) and cochlear implant sound processor off (CI-OFF). The data obtained in the evaluations were compared between the implanted ear and the non-implanted ear between the CI-ON and CI-OFF states within the study group and between the study group and the control group.
When the CI-ON and CI-OFF conditions in the study group were compared, no significant difference was found (p > 0.05). Similarly, no significant difference was found between the implanted ear and the non-implanted ear (p > 0.05). Also, there was no significant difference in the comparisons between the study group and the control group (p > 0.05).
vHIT is a functional test method that can be used in children to test vestibular function after cochlear implant. vHIT is a comfortable test to use after cochlear implantation to demonstrate the functionality of the vestibular system. And it provides consistent results regardless of whether the speech processor is on or off.
内耳的变化会同时影响耳蜗和前庭，这些变化在耳蜗植入手术后可以观察到。本研究的目的是评估单侧耳蜗植入对儿童前庭眼反射（VOR）的影响。
本研究纳入了 29 名年龄在 7-18 岁的单侧耳蜗植入儿童作为研究组，同时纳入了 32 名听力正常的儿童作为对照组。使用 vHIT 评估 VOR，并将单侧 CI 用户的结果与对照组进行比较。研究组在两种不同情况下进行评估：耳蜗植入声音处理器开启（CI-ON）和耳蜗植入声音处理器关闭（CI-OFF）。在研究组内，比较了植入耳和非植入耳在 CI-ON 和 CI-OFF 状态下的评估结果，并将研究组与对照组进行了比较。
当比较研究组的 CI-ON 和 CI-OFF 状态时，未发现显著差异（p>0.05）。同样，在植入耳和非植入耳之间也未发现显著差异（p>0.05）。此外，在研究组与对照组之间的比较中也未发现显著差异（p>0.05）。
vHIT 是一种可用于儿童的功能性测试方法，可用于测试耳蜗植入后前庭功能。vHIT 是一种在耳蜗植入后使用的舒适测试方法，可用于证明前庭系统的功能。并且，无论言语处理器是开启还是关闭，它都能提供一致的结果。
