This study examined patients with normal hearing thresholds who had trouble understanding speech in noise. We used electrocochleography (ECochG) to detect and compare SP/AP amplitude area ratios, a potential indicator of cochlear synaptopathy, and investigate speech perception disorder in noise.
The study included 68 people aged between 18 and 65 years, 35 patients and 33 healthy volunteers, who applied to the otorhinolaryngology clinic between November 2023 and March 2024 with a 2-month history of difficulty understanding speech in noisy environments. Everyone was given a tiptrode electrode ECochG test, and the results were compared between groups. An ECochG test was recorded with tiptrode electrodes and was performed on all participants, and the results were compared between groups.
In the ECochG test, the summation potential/action potential (SP/AP) amplitude and area ratios of patients who had difficulty understanding speech in a noisy environment were statistically higher than those of the control group.
ECochG testing may provide additional evidence to evaluate auditory nerve pathways.
本研究对听力阈值正常但在噪声环境中难以理解言语的患者进行了检查。我们使用耳蜗电图（ECochG）来检测和比较SP/AP振幅面积比（一种潜在的耳蜗突触病变指标），并研究噪声环境中的言语感知障碍。
该研究纳入了68名年龄在18至65岁之间的人，其中35名患者和33名健康志愿者，他们在2023年11月至2024年3月期间因有2个月在嘈杂环境中难以理解言语的病史而前往耳鼻喉科诊所就诊。所有人均接受了针电极ECochG测试，并对组间结果进行了比较。使用针电极记录了ECochG测试结果，并对所有参与者进行了该测试，然后对组间结果进行了比较。
在ECochG测试中，在嘈杂环境中难以理解言语的患者的总和电位/动作电位（SP/AP）振幅和面积比在统计学上高于对照组。
ECochG测试可为评估听觉神经通路提供额外证据。
