The available evidence about hearing loss in Coronavirus disease (COVID-19) patients mostly show sensorineural hearing loss, and the long-term effects of COVID-19 on auditory thresholds are unknown. This study aimed to compare the auditory threshold results in COVID-19 patients (several months after infection) with a control group.
The clinical diagnosis of COVID-19 was confirmed with positive polymerase chain reaction findings and radiology images. Hearing evaluation was performed with an audiometry test and a calibrated audiometer in a sound-treated room. The results of 177 patients were compared with those of the 589 matched control group. In both groups, subjects over 50 years old or with any history of ear disease were excluded from the study.
The time interval between infection with COVID-19 and hearing tests was 170.51±98.38 days. There was no significant difference between the auditory thresholds in different frequencies in both groups. Also, no significant difference was observed between the auditory thresholds of the two groups in the first, second, and third trimesters after being infected.
This study did not show the long-term effects of COVID-19 on auditory thresholds, and the findings do not support hearing loss as a long-term COVID symptom.
关于冠状病毒病（COVID-19）患者听力损失的现有证据大多显示为感音神经性听力损失，而COVID-19对听觉阈值的长期影响尚不清楚。本研究旨在比较COVID-19患者（感染数月后）与对照组的听觉阈值结果。
COVID-19的临床诊断通过聚合酶链反应结果阳性和放射学图像得以证实。在经过声学处理的房间内，使用听力测试和校准听力计进行听力评估。将177例患者的结果与589例匹配对照组的结果进行比较。在两组中，50岁以上或有任何耳部疾病史的受试者均被排除在研究之外。
COVID-19感染与听力测试之间的时间间隔为170.51±98.38天。两组不同频率的听觉阈值之间无显著差异。此外，在感染后的第一、第二和第三孕期，两组的听觉阈值之间也未观察到显著差异。
本研究未显示COVID-19对听觉阈值的长期影响，研究结果不支持听力损失是COVID-19的长期症状。
