Abstract

Carbon monoxide (CO) can cause "irreversible" severe-to-profound sensorineural hearing loss. However, there are few reports of detailed hearing test results. Here, we report a case of acute sensorineural hearing loss caused by acute CO poisoning with partial hearing recovery, evaluated by a detailed hearing examination. A 25-year-old woman was brought to the emergency department for attempted suicide. On admission, her consciousness was impaired, and she was treated for severe CO poisoning, including using hyperbaric-oxygen therapy. After regaining consciousness, symptoms of hearing loss and tinnitus were discovered, and a detailed audiological examination revealed bilateral hearing loss, suggesting cochlear damage. Steroids were systemically administered, and her hearing impairment was partially resolved. Sensorineural hearing loss caused by acute CO poisoning includes cochlear pathology and may be partially treatable. The early evaluation of hearing in patients with severe CO poisoning is advisable for early treatment.

急性一氧化碳中毒引起的感觉神经性听力损失。

一氧化碳（CO）可导致“不可逆”的严重至深度感音神经性听力损失。然而，很少有详细的听力测试结果的报告。在此，我们报告了一例由急性一氧化碳中毒引起的急性感音神经性听力损失，并通过详细的听力检查评估了部分听力恢复。一名25岁女子因自杀未遂被送往急诊室。入院时，她的意识受损，并接受了严重一氧化碳中毒的治疗，包括使用高压氧治疗。恢复意识后，发现了听力损失和耳鸣的症状，详细的听力检查显示双侧听力损失，表明耳蜗受损。类固醇被系统地给药，她的听力障碍得到了部分解决。急性一氧化碳中毒引起的感觉神经性听力损失包括耳蜗病理学，可能部分可以治疗。早期评估严重CO中毒患者的听力是早期治疗的可取方法。
