Abstract：
BACKGROUND: Numerous studies have found that patients experiencing sudden sensorineural hearing loss (SSHL), with or without accompanying vertigo, often show impaired vestibular function. However, there is a dearth of studies analyzing vestibular-evoked myogenic potentials (VEMPs) in SSHL patients across various age groups.
OBJECTIVE: To investigate vestibular condition in SSHL patients across various age demographics.
METHODS: Clinical data of 84 SSHL patients were investigated retrospectively. Audiometry, cervical vestibular evoked myogenic potentials (c-VEMPs), and ocular vestibular evoked myogenic potentials (o-VEMPs) were conducted on these patients. Parameters assessed included the latencies of P1 and N1 waves, as well as the amplitudes of P1-N1 waves. Moreover, the study evaluated the influence of factors such as sex, affected side, configuration of hearing loss, and presence of accompanying vertigo.
RESULTS: Among the 84 SSHL patients, no significant differences were observed among the three groups in terms of gender, affected side, and the presence or absence of vertigo. Group II (aged 41-60 years) had the highest number of SSHL cases. The rates of absent o-VEMPs in the affected ears were 20.83%, 31.58%, and 22.72% for the three age groups, respectively, with no statistically significant difference among them. The rates of absent c-VEMPs in the affected ears were 8.3%, 34.21%, and 18.18% for the three age groups, respectively, with significant differences. In the unaffected ears, there were differences observed in the extraction rates of o-VEMPs in the unaffected ears among the age groups. In the three age groups, no significant differences were noted in the three age groups in the latencies of P1 and N1 waves or in the amplitude of N1-P1 waves for c-VEMPs and o-VEMPs, either on the affected side or on the unaffected side, across the three age groups.
CONCLUSIONS: The extraction rate of VEMPs is more valuable than parameters. Regardless of the presence of vertigo, vestibular organs are involved in SSHL. Notably, SSHL patients aged 41-60 appear more susceptible to damage to the inferior vestibular nerve and saccule.

摘要：
背景：许多研究发现，患有突发性感觉神经性听力损失（SSHL）的患者，伴有或不伴有眩晕，常显示前庭功能受损。然而,缺乏分析不同年龄段SSHL患者前庭诱发肌源性电位(VEMPs)的研究.
目的：调查不同年龄人口统计学中SSHL患者的前庭状况。
方法：对84例SSHL患者的临床资料进行回顾性分析。测听法,宫颈前庭诱发肌源性电位（c-VEMPs），并对这些患者进行了眼前庭诱发的肌源性电位（o-VEMPs）。评估的参数包括P1波和N1波的延迟，以及P1-N1波的振幅。此外，该研究评估了性别等因素的影响，患侧,听力损失的配置，并伴有眩晕。
结果：在84例SSHL患者中，三组在性别方面没有观察到显著差异，患侧,以及是否存在眩晕。II组（年龄41-60岁）的SSHL病例数最高。受影响的耳朵中o-VEMPs的缺失率为20.83％，31.58%，三个年龄组为22.72%，分别,它们之间没有统计学上的显著差异。受影响的耳朵中c-VEMPs的缺失率为8.3％，34.21%,三个年龄组为18.18%，分别,具有显著差异。在未受影响的耳朵里，在未受影响的耳中,o-VEMPs的提取率在各年龄组间存在差异.在三个年龄组中，在三个年龄组中，c-VEMP和o-VEMP的P1和N1波的潜伏期或N1-P1波的振幅没有显着差异，在受影响的一侧或未受影响的一侧，在三个年龄组。
结论：VEMPs的提取率比参数更有价值。不管是否存在眩晕,前庭器官参与SSHL。值得注意的是,41-60岁的SSHL患者似乎更容易损伤下前庭神经和球囊。
