AI Article Synopsis
- The study investigates vestibular function in patients with idiopathic sudden sensorineural hearing loss who experience dizziness but not true vertigo.
- A total of 30 patients were compared based on their results from the video head impulse test, showing that 30% of symptomatic patients had abnormal findings.
- Ultimately, no significant differences in vestibular function were found between the symptomatic and asymptomatic groups, suggesting that the damage in these patients primarily affects the cochlea or cochlear nerve.
Article Abstract
Objective: Idiopathic sudden sensorineural hearing loss may be accompanied by dizziness without true vertigo. This study used the video head impulse test to evaluate vestibular function in idiopathic sudden sensorineural hearing loss patients who described experiencing dizziness and not true vertigo.
Methods: A prospective study was conducted of 30 consecutive patients diagnosed with idiopathic sudden sensorineural hearing loss with dizziness without true vertigo. A comparison of the video head impulse test results of the patients who complained of dizziness (symptomatic group) with a group of patients with idiopathic sudden sensorineural hearing loss and no dizziness (asymptomatic) was performed.
Results: Nine patients (30 per cent) were symptomatic. Two of those patients had abnormal video head impulse test findings. Seven patients in the asymptomatic group (7 out of 21, 33 per cent) presented with abnormal video head impulse test results. No significant difference in vestibular function between the two groups was detected by the video head impulse test.
Conclusion: The site of insult in patients with idiopathic sudden sensorineural hearing loss without true vertigo is usually limited to the cochlea or the cochlear nerve.
