结论。在所有突发性感音神经性听力损失（SSNHL）中，“罕见耳鸣”组的听力预后比“经常耳鸣”组差，但当仅限于伴有耳鸣的 SSNHL 时，“持续时间较短”组的预后要好于“持续时间较长”组。这表明耳鸣本身可能不是听力预后不良的征兆，但可能是受损听觉系统开始修复的重要声音。目标。我们检查了 SSNHL 发病时的听力改善率 (HIR) 和耳鸣，以阐明伴随 SSNHL 的耳鸣的预后价值。患者和方法。 50 名 SSNHL 患者接受了全身类固醇治疗。通过比较治疗前后的听力水平来确定听力恢复情况。通过耳鸣评分问卷对耳鸣进行主观评价。在开始时获得主观耳鸣感觉“响度”、“持续时间”和“烦躁度”五级评价的分数。结果。在“持续时间”方面，当我们将所有病例分为“罕见耳鸣”组和“经常耳鸣”组时，“罕见耳鸣”组的 HIR 显着低于“经常耳鸣”组。当仅限于“经常耳鸣”组时，“持续时间较短”的 HIR 显着高于“持续时间较长”的 HIR。
Conclusions. The 'tinnitus-rare' group had a poorer prognosis for hearing than the 'tinnitus-often' group in all sudden sensorineural hearing loss (SSNHL), although the 'shorter duration' group had better prognosis than the 'longer duration' when restricted to SSNHL accompanied by tinnitus. This indicates that tinnitus itself may not be a sign for poor hearing prognosis but might be an essential sound for the initiation of repair of a damaged auditory system. Objectives. We examined the hearing improvement rate (HIR) and tinnitus at the onset of SSNHL to elucidate the prognostic value of tinnitus accompanying SSNHL. Patients and methods. Fifty patients with SSNHL were treated with systemic administration of steroids. Hearing recovery was determined by comparing the hearing levels before and after treatment. Tinnitus was subjectively evaluated by the tinnitus scoring questionnaire. The score for the five-step evaluation of the subjective tinnitus feelings 'loudness', 'duration' and 'annoyance' was obtained at the onset. Results. In terms of 'duration', when we divided all the cases into 'tinnitus-rare' group and 'tinnitus-often' group, HIR in the 'tinnitus-rare' group was significantly lower than that in 'tinnitus-often' group. When restricted to the 'tinnitus-often' group, HIR for 'shorter duration' was significantly higher than that for 'longer duration'.
