Summary
Sensorineural hearing loss often co-occurs with vestibular dysfunction, leading to vertigo and dizziness. Peripheral vestibular dysfunction was more frequent in patients with residual hearing or deafness.
Area of Science:
- Otorhinolaryngology
- Neurology
- Audiology
Context:
- The inner ear's proximity of auditory and vestibular structures suggests shared etiopathogenic factors for sensorineural hearing loss, vertigo, and dizziness.
- Vestibular system dysfunction is frequently observed alongside sensorineural hearing loss.
Purpose:
- To determine the prevalence of vestibular dysfunction in patients with sensorineural hearing loss.
- To analyze the relationship between hearing loss severity/type and vestibular system impairment.
Summary:
- A study of 126 sensorineural hearing loss patients revealed 50% experienced vertigo and 30% dizziness.
- Abnormal ENG results were found in 72% of patients, particularly in positional and ocular-motor tests.
- Peripheral and mixed vestibular lesions were more common in patients with vertigo, with a higher incidence of peripheral dysfunction in those with residual hearing or deafness.
Impact:
- Findings highlight the significant overlap between hearing and vestibular disorders.
- Suggests comprehensive audiological and vestibular evaluation for patients with sensorineural hearing loss.
- Identifies specific patient groups (e.g., residual hearing/deafness) at higher risk for vestibular dysfunction.
