Abstract

Background: Sudden sensorineural hearing loss with vertigo (SHLV) and vestibular neuritis (VN) can result in prolonged dizziness.

Objectives: This study aimed to compare the video head impulse test (vHIT) of patients with SHLV and VN.

Methods: Fifteen patients with SHLV and 21 patients with VN who visited the Vertigo/Dizziness Center of our hospital between December 2016 and February 2023 were included. vHIT was performed at the time of admission, and the VOR gain and catch up saccade (CUS) in the three types of semicircular canals (SCCs) were analyzed.

Results: Pathologic vHIT results were observed most frequently in the posterior SCC (73%), followed by lateral (53%) and anterior (13%) SCCs in the SHLV group. In contrast, pathologic vHIT results were observed most frequently in the lateral SCC (100%), followed by the anterior (43%) and posterior SCC (24%) SCCs in the VN group. Pathological vHIT results in the lateral and posterior SCC showed significant differences between the two groups, but for anterior SCC, no significant differences were found.

Conclusions and significance: Comparison of the two vHIT results revealed differences in the SCC dysfunction patterns. This may be due to the different pathophysiological mechanisms of the two vestibular disorders, which may result in prolonged vertigo.

突发性感音神经性听力损失伴眩晕和前庭神经炎慢性期患者在视频头脉冲试验中的半规管功能差异。

背景：突发性感音神经性听力损失伴眩晕（SHLV）和前庭神经炎（VN）可导致长时间头晕：本研究旨在比较 SHLV 和 VN 患者的视频头脉冲试验（vHIT）：方法：纳入2016年12月至2023年2月期间在我院眩晕/头晕中心就诊的15例SHLV患者和21例VN患者，在入院时进行vHIT，并分析三种半规管（SCC）的VOR增益和追赶囊卡（CUS）：结果：在SHLV组中，病理性vHIT结果最常见于后方SCC（73%），其次是侧方SCC（53%）和前方SCC（13%）。相比之下，VN 组的病理 vHIT 结果最常见于侧部 SCC（100%），其次是前部 SCC（43%）和后部 SCC（24%）。两组侧部和后部 SCC 的病理 vHIT 结果显示有显著差异，但前部 SCC 没有发现显著差异：比较两组 vHIT 结果发现，SCC 功能障碍模式存在差异。这可能是由于两种前庭疾病的病理生理机制不同，从而可能导致长时间眩晕。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
