Idiopathic sudden sensorineural hearing loss (ISSHL) is a hearing impairment greater than 30 dB at three consecutive frequencies developing in less than 3 days. The aim of this study was to evaluate VEMPs and caloric testing in patients affected by ISSHL without vertigo.
We retrospectively evaluated 35 subjects affected by ISSHL. The audio-vestibular investigation consisted of pure-tone and speech audiometry, impedance, bithermal caloric testing, oVEMPs and cVEMPs.
VEMPS were abnormal in 21 patients (60%): cVEMPs in 12 (34.2%) and oVEMPs in 19 (54.2%). 10 patients (28.5%) presented with both c-and oVEMPs altered. Subjects without vestibular involvement showed a significant lower PTA in the affected ear both at admission and at discharge. Recovery rate was significantly higher in group without vestibular involvement.
The evaluation of the vestibular system can be useful for predicting the auditory recovery in patients without vertigo also.
特发性突发性聋（ISSHL）是指在不到 3 天的时间内，连续三个频率出现大于 30dB 的听力障碍。本研究的目的是评估无眩晕 ISSHL 患者的前庭诱发肌源性电位（VEMPs）和冷热试验。
我们回顾性评估了 35 例 ISSHL 患者。听觉前庭检查包括纯音和言语测听、阻抗、双耳温差试验、oVEMP 和 cVEMP。
21 例（60%）VEMP 异常：cVEMP 异常 12 例（34.2%），oVEMP 异常 19 例（54.2%）。10 例（28.5%）患者 cVEMP 和 oVEMP 均异常。无前庭受累的患者在入院和出院时患耳的纯音听阈平均值（PTA）均显著降低。无前庭受累组的恢复率明显更高。
评估前庭系统对于预测无眩晕患者的听力恢复也可能是有用的。
