Abstract

Background

Bithermal caloric irrigation, video head impulse test (vHIT), and rotational testing are commonly used to assess peripheral vestibular function, but the relative clinical utility of each test in differentiating patients with peripheral vestibulopathy is debated.

Objectives

To determine whether (1) the combination of two or more vestibular tests enhances diagnostic utility over a single test; (2) abnormal test results on vestibular tests correlate with one another.

Methods

Retrospective analysis of data collected from multidisciplinary vestibular clinics at two academic medical centers from 2016 to 2022.

Results

150 patients (54.10 ± 15.09 years, 88 females) were included. No individual test was significantly better at predicting the presence of peripheral vestibular damage (p > 0.05). vHIT test results improved significantly when combined with either the caloric test (p = 0.007) or rotary chair test (p = 0.039). Caloric and rotational testing had high sensitivity (74.65% and 76.06%, respectively) and specificity (83.54% and 78.48%, respectively). vHIT demonstrated excellent specificity (89.87%) but poor sensitivity (47.89%). Caloric, vHIT, and rotary chair tests results did not correlate with one another (p > 0.05).

Conclusions

Vestibular function tests have comparable diagnostic utility, yet each offers unique advantages. Caloric and rotational testing may be best suited for screening peripheral damage and vHIT may function ideally as a confirmatory test.

外周性和中枢性前庭功能障碍患者前庭功能测试的效用比较
背景热量灌流、视频头脉冲试验(vHIT)和旋转试验常用于评估外周前庭功能,但对于每种试验在区分外周前庭病变患者方面的相对临床效用还存在争议。方法回顾性分析两个学术医学中心多学科前庭门诊从2016年至2022年收集的数据。结果纳入150名患者(54.10 ± 15.09岁,88名女性)。在预测是否存在外周前庭损伤方面,没有任何单项测试具有明显优势(p >0.05)。vHIT测试结果在与热量测试(p = 0.007)或旋转椅测试(p = 0.039)相结合时有明显改善。热量测试和旋转测试具有较高的灵敏度(分别为 74.65% 和 76.06%)和特异性(分别为 83.54% 和 78.48%)。卡路里、vHIT 和转椅测试结果之间没有相关性(p > 0.05)。热量测试和旋转测试可能最适合用于筛查外周损伤,而 vHIT 可能是理想的确诊测试。

期刊介绍: Journal of Otology is an open access, peer-reviewed journal that publishes research findings from disciplines related to both clinical and basic science aspects of auditory and vestibular system and diseases of the ear. This journal welcomes submissions describing original experimental research that may improve our understanding of the mechanisms underlying problems of basic or clinical significance and treatment of patients with disorders of the auditory and vestibular systems. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines. Journal of Otology welcomes contributions from scholars in all countries and regions across the world.
