AIM
to investigate the effect of chronic noise exposure on vestibular function of subjects without clinical evidence of vestibular disorders and with documented cochlear damage from noise.
SUBJECTS AND METHODS
25 patients with chronic noise-induced hearing loss (NIHL) and without vestibular complaints (group A) and 25 matched controls with sensorineural hearing loss without noise exposure (group B), underwent audiological and vestibular test including caloric and cervical vestibular-evoked myogenic potentials tests (cVEMPs).
RESULTS
In subjects chronically exposed to noise, similarly to that of the auditory threshold, an increase in the evocation threshold of VEMPs has been documented, statistically significant (p<0,05) and independent of the performance of the auditory threshold. p1-n1 amplitude values showed a significant difference between group A and group B. No significant difference for p1-n1 latencies between the two groups was found.
CONCLUSION
We have documented the possibility of vestibular lesion, along with cochlear damage, related to chronic acoustic trauma.
目的
研究长期噪声暴露对无前庭疾病临床证据但有噪声所致耳蜗损伤记录的受试者前庭功能的影响。
研究对象与方法
25例慢性噪声性听力损失（NIHL）且无前庭主诉的患者（A组）和25例匹配的无噪声暴露的感音神经性听力损失对照者（B组）接受了听力学和前庭测试，包括冷热试验和颈前庭诱发肌源性电位测试（cVEMP）。
结果
在长期暴露于噪声的受试者中，与听阈类似，已记录到VEMP诱发阈值升高，具有统计学意义（p<0.05），且与听阈表现无关。p1-n1振幅值在A组和B组之间存在显著差异。两组之间p1-n1潜伏期未发现显著差异。
结论
我们已证明，除耳蜗损伤外，慢性声创伤还可能导致前庭病变。
