Abstract：
Viruses are often implicated as a cause of sensorineural hearing loss (SNHL), particularly sudden cases, including COVID-19. Determining the viral mechanism that leads to hearing loss is necessary for its future prevention and treatment. The 47-year-old woman who is the subject of this case study presented with sudden SNHL following multiple infections of COVID-19. Following a trial of a contralateral routing of sound device, she received a right cochlear implant (CI). Following a period of high performance, additional cases of COVID-19 infection and device failure issues resulted in the explant/reimplant of 1 ear and implantation of the contralateral ear. Despite extensive rehabilitation after these events, the patient continues to experience difficulties in speech understanding, not reaching her initial high levels of right ear performance. Further research is needed to determine the implications of COVID-19 as it relates to SNHL. This case study aimed to highlight the course of treatment and provide insight into the impact of COVID-19 on sudden hearing loss and its relationship to CI performance.
摘要：
病毒通常被认为是感音神经性听力损失（SNHL）的原因。特别是突发病例，包括COVID-19。确定导致听力损失的病毒机制对于其未来的预防和治疗是必要的。这项病例研究的对象是这位47岁的女性，在新冠肺炎多重感染后出现了突发性SNHL。在对声音设备的对侧路由进行试验之后，她接受了右耳蜗植入（CI）。经过一段时间的高性能，其他病例的COVID-19感染和装置故障问题导致1只耳朵的外植体/再植入和对侧耳朵的植入。尽管在这些事件之后得到了广泛的康复，患者继续在言语理解方面遇到困难，没有达到她最初的高水平的右耳表现。需要进一步的研究来确定COVID-19与SNHL相关的含义。本案例研究旨在强调治疗过程，并深入了解COVID-19对突发性听力损失的影响及其与CI表现的关系。
