Abstract

Purpose: The purpose of this study was to evaluate the effect of noise exposure on otolith function measures of video ocular counter roll (vOCR), ocular vestibular evoked myogenic potential (oVEMP), cervical VEMP (cVEMP), and subjective visual vertical (SVV). Additionally, this study compared the vOCR results with other otolith function measures: cVEMP, oVEMP, and SVV.

Method: This was a cross-sectional, between-group prospective study that compared otolith function tests between noise exposure groups. Thirty-three adults between the ages of 40-60 years with no middle ear pathology, history of balance disorder, neurologic pathology, systemic diseases, or receiving ototoxic medications were included in the study. Group 1 included 17 adults (34 ears) with low-risk noise exposure, and Group 2 included 16 adults (32 ears) with high-risk noise exposure. Independent samples t tests were used to assess group mean differences for dependent variables. The independent variable was group with two levels (low risk and high risk). The dependent variables were Noise Exposure Structured Interview (NESI) score, vOCR torsion, cVEMP amplitude, oVEMP amplitude, and SVV angle. Additional analyses were completed using Pearson correlation to evaluate the relationship of vOCR to the other otolith function tests and NESI score to the otolith function tests.

Results: The results indicated significantly decreased vOCR torsion, cVEMP amplitude, and oVEMP amplitude in individuals with high-risk noise exposure compared with those in the low-risk group. Significant correlations were found for NESI scores as well as vOCR and oVEMP measures.

Conclusions: This study describes the concomitant degeneration of the auditory and vestibular systems from noise exposure affecting otolith function, as measured by audiologic testing and otolith testing. vOCR appears to be sensitive to this degeneration, indicating that vOCR could be used as a vestibular screening measure for patients with noise exposure and/or suspected utricle dysfunction.

噪音暴露对视频眼球计数器滚动测量的影响。

目的：本研究旨在评估噪声暴露对视频眼球反转（vOCR）、眼前庭诱发电位（oVEMP）、颈椎 VEMP（cVEMP）和主观视觉垂直（SVV）等耳石功能测量的影响。此外，本研究还将 vOCR 结果与其他耳石功能测量方法（cVEMP、oVEMP 和 SVV）进行了比较：这是一项横断面、组间前瞻性研究，比较了不同噪声暴露组的耳石功能测试结果。研究对象包括 33 名年龄在 40-60 岁之间、无中耳病变、无平衡障碍史、无神经系统病变、无全身性疾病或正在服用耳毒性药物的成年人。第 1 组包括 17 名成人（34 耳），属于低风险噪音暴露；第 2 组包括 16 名成人（32 耳），属于高风险噪音暴露。独立样本 t 检验用于评估因变量的组均差异。自变量为两组（低风险和高风险）。因变量为噪声暴露结构化访谈（NESI）评分、vOCR 扭转、cVEMP 振幅、oVEMP 振幅和 SVV 角度。此外，还使用皮尔逊相关分析法评估了 vOCR 与其他耳石功能测试的关系，以及 NESI 评分与耳石功能测试的关系：结果：结果表明，与低风险组相比，高风险噪音暴露者的 vOCR 扭转、cVEMP 振幅和 oVEMP 振幅明显下降。NESI评分以及vOCR和oVEMP测量值之间存在明显的相关性：本研究描述了噪声暴露影响耳石功能所导致的听觉和前庭系统同时退化的情况，这可以通过听力学测试和耳石测试来测量。vOCR 似乎对这种退化很敏感，这表明 vOCR 可用作噪声暴露和/或疑似耳石功能障碍患者的前庭筛查指标。

期刊介绍： Mission: AJA publishes peer-reviewed research and other scholarly articles pertaining to clinical audiology methods and issues, and serves as an outlet for discussion of related professional and educational issues and ideas. The journal is an international outlet for research on clinical research pertaining to screening, diagnosis, management and outcomes of hearing and balance disorders as well as the etiologies and characteristics of these disorders. The clinical orientation of the journal allows for the publication of reports on audiology as implemented nationally and internationally, including novel clinical procedures, approaches, and cases. AJA seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work. Scope: The broad field of clinical audiology, including audiologic/aural rehabilitation; balance and balance disorders; cultural and linguistic diversity; detection, diagnosis, prevention, habilitation, rehabilitation, and monitoring of hearing loss; hearing aids, cochlear implants, and hearing-assistive technology; hearing disorders; lifespan perspectives on auditory function; speech perception; and tinnitus.
