Abstract：
BACKGROUND: Patients with sensorineural hearing loss suffer concomitant vestibular dysfunction that is more prevalent in patients with inner ear anomaly and could be aggravated with cochlear implantation. To assess the vestibular dysfunction in patients with cochlear implantation, we compared their results with those of patients with and without inner ear anomaly.
METHODS: This is a historical cohort study lasting for 20 years on 50 patients with cochlear implantation. All patients underwent dynamic posturography and Bruininks-Oseretsky Test.
RESULTS: Twenty-two (44%) of the participants showed some types of inner ear anomaly. The frequency of abnormal Bruininks-Oseretsky Test was 45.5% and 10.7% (P = .005, odds ratio [OR] = 6.9). Abnormal composite was seen in 77.3% and 21.4%, respectively (P < .001; OR = 12.5). The mean strategy score in the fifth condition of the sensory organization test was 25.0 ± 20.4 in patients with inner ear anomaly, whereas it was 44.1 ± 18.9 in those without it (P = .001).
CONCLUSIONS: Balance capability in cochlear implantation patients with inner ear anomaly compared to those without inner ear anomaly was worse. More vestibular rehabilitation treatment plans are suggested for these patients.

摘要：
背景：感音神经性听力损失患者并发前庭功能障碍在内耳异常患者中更为普遍，并可随着人工耳蜗植入而加重。评估人工耳蜗植入术患者的前庭功能障碍。我们将他们的结果与有和没有内耳异常的患者的结果进行了比较。
方法：这是一项历时20年的历史性队列研究，研究对象为50例人工耳蜗植入患者。所有患者均接受动态姿势造影和Bruinininks-Oseretsky测试。
结果：22名（44％）的参与者表现出某些类型的内耳异常。异常的Bruinininks-Oseretsky测试的频率分别为45.5％和10.7％（P=.005，比值比[OR]=6.9）。异常复合材料分别为77.3%和21.4%，分别为(P<.001；OR=12.5)。内耳异常患者的感觉组织测试第五状态的平均策略评分为25.0±20.4，而没有它的患者为44.1±18.9（P=.001）。
结论：与没有内耳异常的人工耳蜗植入患者相比，内耳异常的平衡能力较差。建议为这些患者提供更多的前庭康复治疗计划。
