Tinnitus is the perception of sound in the ears or head without any external or internal acoustic stimulation, and it is usually associated with hearing loss. In addition, it has been reported that there is a relationship between vestibular problems and sensorineural hearing loss. The aim of this study was to evaluate the vestibular function in patients with tinnitus without hearing loss.
A total of 32 patients who complained only of tinnitus without hearing loss and 30 control subjects without tinnitus or hearing loss were included in this study. Oculomotor and caloric tests were performed on all subjects with videonystagmography. The tinnitus handicap inventory questionnaire, side and duration of tinnitus were recorded in all patients.
The caloric test was abnormal in 13 of 32 (40.6%) patients in the tinnitus group and was normal in all of the control group. Abnormal caloric responses in patients with severe tinnitus were more frequent than in patients with mild or moderate tinnitus. There was a statistically significant difference in the optokinetic gain values between the tinnitus and control groups.
A relationship between tinnitus and abnormal caloric responses was determined. Tinnitus may be the first symptom of vestibular dysfunction.
耳鸣是在没有任何外部或内部声学刺激的情况下，耳朵或头部出现的声音感知，通常与听力损失有关。此外，据报道前庭问题与感音神经性听力损失之间存在关联。本研究的目的是评估无听力损失的耳鸣患者的前庭功能。
本研究纳入了32例仅主诉耳鸣而无听力损失的患者以及30例无耳鸣和听力损失的对照受试者。对所有受试者进行了视频眼震图检查下的动眼神经和冷热试验。记录了所有患者的耳鸣 handicap 问卷、耳鸣的侧别和持续时间。
耳鸣组32例患者中有13例（40.6%）冷热试验异常，而对照组全部正常。重度耳鸣患者的冷热反应异常比轻度或中度耳鸣患者更常见。耳鸣组和对照组之间的视动增益值存在统计学显著差异。
确定了耳鸣与异常冷热反应之间的关系。耳鸣可能是前庭功能障碍的首发症状。
