Abstract

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.

慢性噪声暴露对前庭系统的亚临床影响。

目的:探讨慢性噪声暴露对无前庭功能障碍临床证据和有耳蜗噪声损伤记录的受试者前庭功能的影响。对象和方法:25例无前庭不适的慢性噪声性听力损失(NIHL)患者(A组)和25例无噪声暴露的感音神经性听力损失患者(B组)进行听力学和前庭测试，包括热量和颈前庭诱发肌电位测试(cvemp)。结果:在长期暴露于噪音的受试者中，与听觉阈值相似，vemp的唤起阈值增加，具有统计学意义(结论:我们已经记录了与慢性听觉创伤相关的前庭病变以及耳蜗损伤的可能性。
