Summary
Audiovestibular tests like auditory brain stem response (ABR) and vestibular-evoked myogenic potential (VEMP) predict hearing recovery in severe sudden sensorineural hearing loss (SSHL). Vertigo indicates a worse prognosis in profound SSHL.
Area of Science:
- Neuroscience
- Audiology
- Otolaryngology
Background:
- Sudden sensorineural hearing loss (SSHL) is a complex condition with varying recovery rates.
- Predicting hearing outcomes in SSHL is crucial for patient management and treatment decisions.
- Audiovestibular function tests may offer insights into prognosis.
Purpose of the Study:
- To investigate the correlation between auditory brain stem response (ABR) and vestibular-evoked myogenic potential (VEMP) tests and hearing outcomes in severe to profound SSHL.
- To identify prognostic factors for hearing recovery in SSHL, controlling for confounding variables.
Main Methods:
- Retrospective review of 88 patients with severe to profound SSHL.
- Analysis of pretreatment hearing levels, ABR, VEMP results, and final hearing outcomes.
- Multivariate analysis using cumulative logits model and stratified analysis for severe and profound SSHL groups.
Main Results:
- Pretreatment hearing levels, vertigo, ABR, and VEMP were significant predictors in overall SSHL.
- In severe SSHL, presence of ABR and VEMP waveforms correlated with better hearing outcomes (p=0.01 and p=0.03, respectively).
- In profound SSHL, vertigo was the only significant negative prognostic factor (p=0.04).
Conclusions:
- ABR and VEMP tests are valuable in assessing severe SSHL prognosis.
- The presence of ABR and VEMP waveforms suggests favorable hearing outcomes in severe SSHL.
- Vertigo is a negative prognostic indicator for profound SSHL, and a predictive table for severe SSHL was proposed.

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
01:29The Vestibular System
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
