We aimed to evaluate the prognostic factors for acute-onset tinnitus associated with unilateral idiopathic sudden sensorineural hearing loss (ISSNHL) and to assess the relationship between these factors and the final recovery.
A total of 770 patients with unilateral ISSNHL were enrolled retrospectively and their medical records reviewed. Patients were classified into two groups according to the presence of acute-onset tinnitus at the initial examination. Patient characteristics and the results of pure-tone audiometry were compared between the two groups initially and 3 months later.
A total of 70.9% (n = 546) of patients had tinnitus initially. There was no significant difference in the mean hearing thresholds of the affected ear irrespective of accompanying tinnitus. In contrast, patients with tinnitus in the affected ear tended to have significantly better mean hearing thresholds in the nonaffected ear (p < 0.05). The logistic regression analysis revealed that better mean hearing thresholds in the nonaffected ear were associated with tinnitus occurrence (p < 0.05). Better hearing thresholds in the nonaffected ear, younger age, absence of dizziness, low-tone hearing loss, and combined intratympanic dexamethasone injection were associated with full recovery (p < 0.05). However, tinnitus was not an independent risk factor for full recovery.
Better contralateral hearing was associated with both an increased incidence of concurrent tinnitus and a better final recovery. However, tinnitus was not related to full recovery.
我们旨在评估与单侧特发性突发性感音神经性听力损失（ISSNHL）相关的急性耳鸣的预后因素，并评估这些因素与最终恢复之间的关系。
回顾性纳入770例单侧ISSNHL患者，并对其病历进行审查。根据初次检查时是否存在急性耳鸣将患者分为两组。比较两组患者初始时和3个月后的患者特征及纯音听力测定结果。
共有70.9%（n = 546）的患者初始时有耳鸣。无论是否伴有耳鸣，患耳的平均听力阈值均无显著差异。相比之下，患耳有耳鸣的患者，其未患耳的平均听力阈值往往显著更好（p < 0.05）。逻辑回归分析显示，未患耳更好的平均听力阈值与耳鸣的发生相关（p < 0.05）。未患耳更好的听力阈值、更年轻的年龄、无头晕、低频听力损失以及鼓室内注射地塞米松联合治疗与完全恢复相关（p < 0.05）。然而，耳鸣并非完全恢复的独立危险因素。
较好的对侧听力与同时发生耳鸣的发生率增加以及更好的最终恢复均相关。然而，耳鸣与完全恢复无关。
