We made hypotheses that tinnitus will appear more likely in patients with sudden deafness with superior hearing in unaffected ear or with more severe acute hearing loss.
A retrospective cohort study was performed. Five hundred forty-one patients were identified with idiopathic sudden sensorineural hearing loss (ISSHL) from January 1995 to August 2006. The exclusion criteria for this study were as follows: bilateral sudden hearing loss and Meniere disease, previous tinnitus or bilateral tinnitus at initial evaluation, and onset of hearing loss less than 7 days. The cohort enrolled 454 patients. The enrolled patients were classified into two groups: patient with acute onset tinnitus in the affected ear and patients without tinnitus at initial visit. Main outcome measures were patient age, the presence or absence of vertigo and tinnitus, audiometric patterns, the severity of hearing loss, and hearing in the unaffected ear.
Better contralateral hearing (n = 220 versus n = 72, P < 0.001) and younger age (48 versus 55 years, P < 0.001) were independently associated with the acute onset of tinnitus in patients with ISSHL. The degree of asymmetry between the ears did not differ significantly between patients with and without tinnitus. The sex, presence of vertigo, shape of audiogram, and severity of hearing loss were not correlated with tinnitus occurrence.
Tinnitus triggered by ISSHL was more frequent in patients with better contralateral hearing and of a younger age, irrespective of the severity of hearing loss on the affected side or the asymmetry between the ears.
我们提出假设，在对侧听力较好或急性听力损失更严重的单侧突发性聋患者中，耳鸣更有可能出现。
这是一项回顾性队列研究。1995 年 1 月至 2006 年 8 月，我们从 541 例特发性突发性聋（ISSHL）患者中筛选出符合条件的患者。本研究的排除标准如下：双侧突发性聋和梅尼埃病，初始评估时双侧耳鸣或双侧耳鸣，听力损失发病时间小于 7 天。该队列纳入了 454 例患者。纳入的患者被分为两组：患耳急性发作耳鸣患者和初始就诊时无耳鸣患者。主要观察指标为患者年龄、是否存在眩晕和耳鸣、听力图模式、听力损失严重程度和对侧听力。
更好的对侧听力（n=220 与 n=72，P<0.001）和更年轻的年龄（48 岁与 55 岁，P<0.001）与 ISSHL 患者耳鸣的急性发作独立相关。有耳鸣和无耳鸣患者之间的耳间不对称程度无显著差异。性别、眩晕的存在、听力图的形状和听力损失的严重程度与耳鸣的发生无关。
ISSHL 引起的耳鸣在对侧听力较好且年龄较小的患者中更为常见，而与患侧听力损失的严重程度或耳间不对称无关。
