OBJECTIVE
Idiopathic sudden sensorineural hearing loss may be accompanied by dizziness without true vertigo. This study used the video head impulse test to evaluate vestibular function in idiopathic sudden sensorineural hearing loss patients who described experiencing dizziness and not true vertigo.
METHODS
A prospective study was conducted of 30 consecutive patients diagnosed with idiopathic sudden sensorineural hearing loss with dizziness without true vertigo. A comparison of the video head impulse test results of the patients who complained of dizziness (symptomatic group) with a group of patients with idiopathic sudden sensorineural hearing loss and no dizziness (asymptomatic) was performed.
RESULTS
Nine patients (30 per cent) were symptomatic. Two of those patients had abnormal video head impulse test findings. Seven patients in the asymptomatic group (7 out of 21, 33 per cent) presented with abnormal video head impulse test results. No significant difference in vestibular function between the two groups was detected by the video head impulse test.
CONCLUSION
The site of insult in patients with idiopathic sudden sensorineural hearing loss without true vertigo is usually limited to the cochlea or the cochlear nerve.
目的
特发性突发性聋患者可能伴有头晕而无真性眩晕。本研究使用视频头脉冲试验评估描述头晕而无真性眩晕的特发性突发性聋患者的前庭功能。
方法
对 30 例连续诊断为特发性突发性聋伴头晕但无真性眩晕的患者进行前瞻性研究。对有头晕症状的患者（症状组）与无头晕的特发性突发性聋患者（无症状组）的视频头脉冲试验结果进行比较。
结果
9 例（30%）患者有症状。其中 2 例视频头脉冲试验结果异常。无症状组 7 例（7/21，33%）视频头脉冲试验结果异常。视频头脉冲试验未发现两组间前庭功能有显著差异。
结论
无真性眩晕的特发性突发性聋患者的损伤部位通常局限于耳蜗或听神经。
