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.

AIM

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.

CONCLUSION

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.

Core Tip: Patients with sudden sensorineural hearing loss (SSHL), whether accompanied by vertigo or not, often show impaired vestibular function. By observing the extraction rate and various parameter indicators of vestibular-evoked myogenic potentials (VEMPs) in different age groups of SSHL patients, we found that the extraction rate of VEMPs is more valuable, and the Group II (aged 41–60 years) with the highest number of SSHL cases, and patients aged 41-60 years had the highest number of profound hearing loss and the lowest cervical-VEMPs extraction rate in affected ear. The results indicates that SSHL aged 41-60 years old patients are more susceptible to damage to the inferior vestibular nerve and saccule.
