INTRODUCTION
Tinnitus is usually associated with hearing loss, and patients with tinnitus and normal hearing are unusual. Neuro-otological findings have not previously been described in tinnitus patients with normal hearing.
AIM
To analyse neuro-otological examination results from a group of tinnitus patients with normal hearing.
MATERIALS AND METHODS
Seventeen normal-hearing tinnitus patients seen over a 10-year period were retrospectively evaluated. Their results were compared with those of a control group of 17 normal subjects without tinnitus.
RESULTS
The main neuro-otological finding in the tinnitus patients was caloric test abnormality: a unilateral canal paresis was present in 15 of the 17 patients. Caloric tests were normal in 15 of the 17 control subjects.
CONCLUSION
We may infer from these results that tinnitus could be the only clinical manifestation of a cochlear - and presumably cochleo-vestibular - lesion, and that unilateral canal paresis may be the only abnormal finding on neuro-otological examination.
引言
耳鸣通常与听力损失相关，耳鸣且听力正常的患者较为少见。此前尚未有文献描述听力正常的耳鸣患者的神经耳科学检查结果。
目的
分析一组听力正常的耳鸣患者的神经耳科学检查结果。
材料与方法
回顾性评估了在10年期间接诊的17例听力正常的耳鸣患者。将他们的检查结果与17例无耳鸣的正常对照者的结果进行比较。
结果
耳鸣患者主要的神经耳科学检查结果为冷热试验异常：17例患者中有15例存在单侧半规管轻瘫。17例对照者中有15例冷热试验结果正常。
结论
从这些结果我们可以推断，耳鸣可能是耳蜗（可能还有耳蜗 - 前庭）病变的唯一临床表现，并且单侧半规管轻瘫可能是神经耳科学检查中唯一的异常发现。
