目的：噪声性听力损失（Noise-induced hearing loss，NIHL）是一种左耳较右耳严重的听力损失。本研究的目的是检查左右侧NIHL优势的利手和声反射参数的可能关联。研究设计：回顾性病例回顾和前瞻性系列。设置：三级中心。患者：研究了三个样本：1）对4,277例噪声性听力损失的军人资料进行回顾性分析，分析其患侧与年龄、性别、噪声暴露时间的关系，和听觉损伤; 2）另外119名NIHL军人被评估为利手和NIHL不对称性的可能关联; 3）51名听力正常受试者被测试为利手的听觉反射阈值和潜伏期。干预：无。主要结果测量：通过背景和噪声相关变量和利手的NIHL不对称性的差异。NIHL是更明显的左耳，无论人口特征，噪声暴露参数，声反射措施，或handedess.Conclusion：听力损失的严重程度的不对称性可能是由于皮质通路，特别是更明显的传出听觉系统的右侧，这降低了右耳耳蜗侮辱的易感性。
Objective: Noise-induced hearing loss (NIHL) is more severe in the left ear than the right ear. The aim of this study was to examine the possible association of handedness and acoustic reflex parameters on right or left NIHL predominance.Study Design: Retrospective case review and prospective series.Setting: Tertiary center.Patients: Three samples were studied: 1) the files of 4,277 army personnel with NIHL were reviewed to analyze the relation between the side affected and age, sex, duration of noise exposure, and acoustic damage; 2) an additional 119 army personnel with NIHL were evaluated for the possible association of handedness and NIHL asymmetry; and 3) fifty-one normal-hearing subjects were tested for threshold and latency of acoustic reflex by handedness.Intervention: None.Main Outcome Measure: Differences in NIHL asymmetry by background and noise-related variables and handedness.Results: NIHL was more pronounced in the left ear, regardless of demographic characteristics, noise exposure parameters, acoustic reflex measures, or handedness.Conclusion: The asymmetry in hearing loss severity may be attributed to the cortical pathways, specifically to the more pronounced efferent auditory system on the right side, which reduces the susceptibility of the right ear to cochlear insult.
